mplayer is a movie player for Linux (runs on many other platforms and CPU architectures, see the documentation). It plays most MPEG/:VOB, AVI, ASF/:WMA/:WMV, RM, QT/:MOV/:MP4, Ogg/:OGM, MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many native and binary codecs. You can watch Video CD, SVCD, DVD, 3ivx, DivX 3/:4/:5 and even WMV movies, too.

MPlayer supports a wide range of video and audio output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca, DirectFB, Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL (and all their drivers), VESA (on every VESA-compatible card, even without X11), some low-level card-specific drivers (for Matrox, 3dfx and ATI) and some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/:Hollywood+. Most of them support software or hardware scaling, so you can enjoy movies in fullscreen mode.

MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/:ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub) and DVD subtitles (SPU streams, VOBsub and Closed Captions).

mencoder (MPlayer's Movie Encoder) is a simple movie encoder, designed to encode MPlayer-playable movies (see above) to other MPlayer-playable formats (see below). It encodes to MPEG-4 (DivX/XviD), one of the libavcodec codecs and PCM/:MP3/:VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has stream copying abilities, a powerful filter system (crop, expand, flip, postprocess, rotate, scale, noise, RGB/:YUV conversion) and more.

gmplayer is MPlayer with a graphical user interface. It has the same options as MPlayer.

Usage examples to get you started quickly can be found at the end of this man page.

Also see the HTML documentation!

MPlayer has a fully configurable, command-driven control layer which allows you to control MPlayer using keyboard, mouse, joystick or remote control (with LIRC). See the -input option for ways to customize it.

keyboard control

Seek backward/:forward 10 seconds. Seek backward/:forward 1 minute. Seek backward/:forward 10 minutes. Decrease/increase current playback speed by 10%. Halve/double current playback speed. Reset playback speed to normal. Go backward/:forward in the playlist. Go forward in the playlist, even over the end. next/:previous playtree entry in the parent list next/:previous alternative source. Pause (pressing again unpauses). Step forward. Pressing once will pause movie, every consecutive press will play one frame and then go into pause mode again (any other key unpauses). Stop playing and quit. Adjust audio delay by +/:- 0.1 seconds. Decrease/:increase volume. Decrease/:increase volume. Mute sound. Cycle through the available audio tracks. Toggle fullscreen (also see -fs). Toggle stay-on-top (also see -ontop).

Select previous/:next channel. Change norm. Change channel list.

mouse control

Seek backward/:forward 1 minute. Decrease/:increase volume.

joystick control

Seek backward/:forward 10 seconds. Seek backward/:forward 1 minute. pause Toggle OSD states: none / seek / seek + timer / seek + timer + total time. Decrease/:increase volume.

Every 'flag' option has a 'noflag' counterpart, e.g. the opposite of the -fs option is -nofs.

If an option is marked as (XXX only), it will only work in combination with the XXX option or if XXX is compiled in.

NOTE: The suboption parser (used for example for -ao pcm suboptions) supports a special kind of string-escaping intended for use with external GUIs.

It has the following format:

%n%string_of_length_n

EXAMPLES:

mplayer -ao pcm:file=%10%C:test.wav test.avi

Or in a script:

mplayer -ao pcm:file=%`expr length "$NAME"`%"$NAME" test.avi

You can put all of the options in configuration files which will be read every time MPlayer/MEncoder is run. The system-wide configuration file 'mplayer.conf' is in your configuration directory (e.g. /etc/:mplayer or /usr/:local/:etc/:mplayer), the user specific one is '~/:.mplayer/:config'. The configuration file for MEncoder is 'mencoder.conf' in your configuration directory (e.g. /etc/:mplayer or /usr/:local/:etc/:mplayer), the user specific one is '~/:.mplayer/:mencoder. User specific options override system-wide options and options given on the command line override either. The syntax of the configuration files is 'option=<value>', everything after a '#' is considered a comment. Options that work without values can be enabled by setting them to 'yes' or '1' or 'true' and disabled by setting them to 'no' or '0' or 'false'. Even suboptions can be specified in this way.

EXAMPLE MPLAYER CONFIGURATION FILE:

# Use Matrox driver by default.
vo=xmga
# I love practicing handstands while watching videos.
flip=yes
# Decode/:encode multiple files from png,
# start with mf://filemask
mf=type=png:fps=25
# Eerie negative images are cool.
vf=eq2=1.0:-0.8

EXAMPLE MENCODER CONFIGURATION FILE:

# Make MEncoder output to a default filename.
o=encoded.avi
# The next 4 lines allow mencoder tv:// to start capturing immediately.
oac=pcm=yes
ovc=lavc=yes
lavcopts=vcodec=mjpeg
tv=driver=v4l2:input=1:width=768:height=576:device=/dev/video0:audiorate=48000
# more complex default encoding option set
lavcopts=vcodec=mpeg4:autoaspect=1
lameopts=aq=2:vbr=4
ovc=lavc=1
oac=lavc=1
passlogfile=pass1stats.log
noautoexpand=1
subfont-autoscale=3
subfont-osd-scale=6
subfont-text-scale=4
subalign=2
subpos=96
spuaa=20

You can also write file-specific configuration files. If you wish to have a configuration file for a file called 'movie.avi', create a file named 'movie.avi.conf' with the file-specific options in it and put it in ~/.mplayer/ or in the same directory as the file.

-codecs-file <filename> (also see -afm, -ac, -vfm, -vc)

Override the standard search path and use the specified file instead of the builtin codecs.conf.

-include <configuration file>

Specify configuration file to be parsed after the default ones.

-msglevel <all=<level>:<module>=<level>:...>

Control verbosity directly for each module. The 'all' module changes the verbosity of all the modules not explicitly specified on the command line. See '-msglevel help' for a list of all modules.

NOTE: Messages printed before the command line is loaded cannot be controlled.

Available levels: complete silence fatal messages only error messages warning messages short hints informational messages status messages (those hidden by -quiet) verbose messages debug level 2 debug level 3 debug level 4

-quiet

Make console output less verbose; in particular, prevents the status line (i.e. A: 0.7 V: 0.6 A-V: 0.068 ...) from being displayed. Particularly useful on slow terminals or broken ones which do not properly handle carriage return (i.e. \r).

-priority <prio> (Windows only)

Set process priority for MPlayer according to the predefined priorities available under Windows. Possible values of <prio>: idle|belownormal|normal|abovenormal|high|realtime WARNING: Using realtime priority can cause system lockup.

-really-quiet (also see -quiet)

Display even less output and status messages than with -quiet.

-v

Increment verbosity level, one level for each -v found on the command line.

-autoq <quality> (use with -vf [s]pp)

Dynamically changes the level of postprocessing depending on the available spare CPU time. The number you specify will be the maximum level used. Usually you can use some big number. You have to use -vf [s]pp without parameters in order for this to work.

-autosync <factor>

Gradually adjusts the A/:V sync based on audio delay measurements. Specifying -autosync 0, the default, will cause frame timing to be based entirely on audio delay measurements. Specifying -autosync 1 will do the same, but will subtly change the A/:V correction algorithm. An uneven video framerate in a movie which plays fine with -nosound can often be helped by setting this to an integer value greater than 1. The higher the value, the closer the timing will be to -nosound. Try -autosync 30 to smooth out problems with sound drivers which do not implement a perfect audio delay measurement. With this value, if large A/:V sync offsets occur, they will only take about 1 or 2 seconds to settle out. This delay in reaction time to sudden A/:V offsets should be the only side-effect of turning this option on, for all sound drivers.

-benchmark

Prints some statistics on CPU usage and dropped frames at the end of playback. Use in combination with -nosound and -vo null for benchmarking only the video codec.

NOTE: With this option MPlayer will also ignore frame duration when playing only video (you can think of that as infinite fps).

-colorkey <number>

Changes the colorkey to an RGB value of your choice. 0x000000 is black and 0xffffff is white. Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix, xover, xv (see -vo xv:ck), xvmc (see -vo xv:ck) and directx video output drivers.

-nocolorkey

Disables colorkeying. Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix, xover, xv (see -vo xv:ck), xvmc (see -vo xv:ck) and directx video output drivers.

-crash-debug (DEBUG CODE)

Automatically attaches gdb upon crash or SIGTRAP. Support must be compiled in by configuring with --enable-crash-debug or by having a .developer file in the source tree.

-edlout <filename> (EDL only)

Creates a new file and writes edit decision list (EDL) records to that file. During playback, when the user hits 'i', an entry to skip over the last two seconds of playback will be written to the file. This provides a starting point from which the user can fine-tune EDL entries later. See DOCS/:HTML/:en/:edl.html for details.

-enqueue (GUI only)

Enqueue files given on the command line in the playlist instead of playing them immediately.

-fixed-vo (BETA CODE!)

Enforces a fixed video system for multiple files (one (un)initialization for all files). Therefore only one window will be opened for all files. Currently the following drivers are fixed-vo compliant: gl, gl2, mga, svga, x11, xmga, xv, xvidix and dfbmga.

-framedrop (also see -hardframedrop)

Skip displaying some frames to maintain A/:V sync on slow systems. Video filters are not applied to such frames. For B-frames even decoding is skipped completely.

-h, -help, --help

Show short summary of options.

-hardframedrop

More intense frame dropping (breaks decoding). Leads to image distortion!

-identify

Show file parameters in an easily parseable format. Also prints more detailed information about subtitle and audio track languages and IDs. The wrapper script TOOLS/:midentify suppresses the other MPlayer output and (hopefully) shellescapes the filenames.

-idle (also see -slave)

Makes MPlayer wait idly instead of quitting when there is no file to play. Mostly useful in slave mode where MPlayer can be controlled through input commands.

-input <commands>

This option can be used to configure certain parts of the input system. Paths are relative to ~/:.mplayer/.

NOTE: Autorepeat is currently only supported by joysticks. Available commands are: Specify input configuration file other than the default ~/:.mplayer/:input.conf. ~/:.mplayer/:<filename> is assumed if no full path is given. Delay in milliseconds before we start to autorepeat a key (0 to disable). Number of key presses to generate per second on autorepeat. Prints all keys that can be bound to commands. Prints all commands that can be bound to keys. Specifies the joystick device to use (default: /dev/:input/:js0). Read commands from the given file. Mostly useful with a FIFO.

NOTE: When the given file is a FIFO MPlayer opens both ends so you can do several 'echo "seek 10" > mp_pipe' and the pipe will stay valid.

-key-fifo-size <2-65000>

Specify the size of the FIFO that buffers key events (default: 10). A FIFO of size n can buffer (n-1) events. If it is too small some events may be lost (leading to "stuck mouse buttons" and similar effects). If it is too big, MPlayer may seem to hang while it processes the buffered events. To get the same behavior as before this option was introduced, set it to 2 for Linux or 1024 for Windows.

-lircconf <filename> (LIRC only)

Specifies a configuration file for LIRC (default: ~/:.lircrc).

-list-options

Prints all available options.

-loop <number>

Loops movie playback <number> times. 0 means forever.

-menu (OSD menu only)

Turn on OSD menu support.

-menu-cfg <filename> (OSD menu only)

Use an alternative menu.conf.

-menu-root <value> (OSD menu only)

Specify the main menu.

-menu-startup (OSD menu only)

Display the main menu at MPlayer startup.

-noconsolecontrols

Prevent MPlayer from reading key events from standard input. Useful when reading data from standard input. This is automatically enabled when - is found on the command line. There are situations where you have to set it manually, e.g. if you open /dev/:stdin (or the equivalent on your system), use stdin in a playlist or intend to read from stdin later on via the loadfile or loadlist slave commands.

-nojoystick

Turns off joystick support.

-nolirc

Turns off LIRC support.

-nomouseinput (X11 only)

Disable mouse button press/:release input (mozplayerxp's context menu relies on this option).

-nortc (RTC only)

Turns off usage of the Linux RTC (realtime clock - /dev/:rtc) as timing mechanism.

-playlist <filename>

Play files according to a playlist file (ASX, Winamp, SMIL, or one-file-per-line format).

NOTE: This option is considered an entry so options found after it will apply only to the elements of this playlist.

FIXME: This needs to be clarified and documented thoroughly.

-rtc-device <device>

Use the specified device for RTC timing.

-shuffle

Play files in random order.

-skin <name> (GUI only)

Loads a skin from the directory given as parameter below the default skin directories, /usr/:local/:share/:mplayer/:Skin/: and ~/.mplayer/:Skin/. EXAMPLE: Tries /usr/:local/:share/:mplayer/:Skin/:fittyfene and afterwards ~/.mplayer/:Skin/:fittyfene.

-slave (also see -input)

Switches on slave mode, in which MPlayer works as a backend for other programs. Instead of intercepting keyboard events, MPlayer will read commands separated by a newline (\n) from stdin.

NOTE: See -input cmdlist for a list of slave commands and DOCS/tech/slave.txt for their description.

-softsleep

Use high-quality software timers instead of the RTC. As precise as the RTC without requiring special privileges. Comes at the price of higher CPU consumption.

-sstep <sec>

Skip <sec> seconds after every frame. The normal framerate of the movie is kept, so playback is accelerated. Since MPlayer can only seek to the next keyframe this may be inexact.

-a52drc <level>

Select the Dynamic Range Compression level for AC3 audio streams. <level> is a float value ranging from 0 to 1, where 0 means no compression and 1 (which is the default) means full compression (make loud passages more silent and vice versa). This option only shows an effect if the AC3 stream contains the required range compression information.

-aid <ID> (also see -alang)

Select audio channel (MPEG: 0-31, AVI/:OGM: 1-99, ASF/:RM: 0-127, VOB(AC3): 128-159, VOB(LPCM): 160-191, MPEG-TS 17-8190). MPlayer prints the available audio IDs when run in verbose (-v) mode. When playing an MPEG-TS stream, MPlayer/:MEncoder will use the first program (if present) with the chosen audio stream.

-alang <language code[,language code,...]> (also see -aid)

Specify a priority list of audio languages to use. Different container formats employ different language codes. DVDs use ISO 639-1 two letter language codes, Matroska and NUT use ISO 639-2 three letter language codes while OGM uses a free-form identifier. MPlayer prints the available languages when run in verbose (-v) mode. EXAMPLE: Chooses the Hungarian language track on a DVD and falls back on English if Hungarian is not available. Plays a Matroska file in Japanese.

-audio-demuxer <[+]name> (-audiofile only)

Force audio demuxer type for -audiofile. Use a '+' before the name to force it, this will skip some checks! Give the demuxer name as printed by -audio-demuxer help. For backward compatibility it also accepts the demuxer ID as defined in libmpdemux/:demuxer.h. -audio-demuxer audio or -audio-demuxer 17 forces MP3.

-audiofile <filename>

Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie.

-audiofile-cache <kBytes>

Enables caching for the stream used by -audiofile, using the specified amount of memory.

-bandwidth <value> (network only)

Specify the maximum bandwidth for network streaming (for servers that are able to send content in different bitrates). Useful if you want to watch live streamed media behind a slow connection. With Real RTSP streaming, it is also used to set the maximum delivery bandwidth allowing faster cache filling and stream dumping.

-cache <kBytes>

This option specifies how much memory (in kBytes) to use when precaching a file or URL. Especially useful on slow media.

-cache-min <percentage>

Playback will start when the cache has been filled up to <percentage> of the total.

-cache-seek-min <percentage>

If a seek is to be made to a position within <percentage> of the cache size from the current position, MPlayer will wait for the cache to be filled to this position rather than performing a stream seek (default: 50).

-cdda <option1:option2> (CDDA only)

This option can be used to tune the CD Audio reading feature of MPlayer. Available options are: Set CD spin speed. Set paranoia level. Values other than 0 seem to break playback of anything but the first track. 0: disable checking (default)

1: overlap checking only

2: full data correction and verification Use specified generic SCSI device. Set atomic read size. Force minimum overlap search during verification to <value> sectors. Assume that the beginning offset of track 1 as reported in the TOC will be addressed as LBA 0. Some Toshiba drives need this for getting track boundaries correct. Add <value> sectors to the values reported when addressing tracks. May be negative. (Never) accept imperfect data reconstruction.

-cdrom-device <path to device>

Specify the CD-ROM device (default: /dev/:cdrom).

-channels <number> (also see -af channels)

Request the number of playback channels (default: 2). MPlayer asks the decoder to decode the audio into as many channels as specified. Then it is up to the decoder to fulfill the requirement. This is usually only important when playing videos with AC3 audio (like DVDs). In that case liba52 does the decoding by default and correctly downmixes the audio into the requested number of channels. To directly control the number of output channels independently of how many channels are decoded, use the channels filter.

NOTE: This option is honored by codecs (AC3 only), filters (surround) and audio output drivers (OSS at least). Available options are: stereo surround full 5.1

-chapter <chapter ID>[-<end chapter ID>] (DVD only)

Specify which chapter to start playing at. Optionally specify which chapter to end playing at (default: 1).

-cookies (network only)

Send cookies when making HTTP requests.

-cookies-file <filename> (network only)

Read HTTP cookies from <filename> (default: ~/.mozilla/ and ~/.netscape/) and skip reading from default locations. The file is assumed to be in Netscape format.

-delay <sec>

audio delay in seconds (positive or negative float value)

NOTE: When used with MEncoder, this is not guaranteed to work correctly with -ovc copy.

-demuxer <[+]name>

Force demuxer type. Use a '+' before the name to force it, this will skip some checks! Give the demuxer name as printed by -demuxer help. For backward compatibility it also accepts the demuxer ID as defined in libmpdemux/:demuxer.h. -demuxer audio or -demuxer 17 forces MP3.

-dumpaudio (MPlayer only)

Dumps raw compressed audio stream to ./stream.dump (useful with MPEG/:AC3). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-dumpfile <filename> (MPlayer only)

Specify which file MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream.

-dumpstream (MPlayer only)

Dumps the raw stream to ./stream.dump. Useful when ripping from DVD or network. If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-dumpvideo (MPlayer only)

Dump raw compressed video stream to ./stream.dump (not very usable). If you give more than one of -dumpaudio, -dumpvideo, -dumpstream on the command line only the last one will work.

-dvbin <options> (DVB only)

Pass the following parameters to the DVB input module, in order to override the default ones: Specifies using card number 1-4 (default: 1). Instructs MPlayer to read the channels list from <filename>. Default is ~/.mplayer/:channels.conf.{sat,ter,cbl,atsc} (based on your card type) or ~/.mplayer/:channels.conf as a last resort.

-dvd-device <path to device> (DVD only)

Specify the DVD device (default: /dev/:dvd). You can also specify a directory that contains files previously copied directly from a DVD (with e.g. vobcopy). Note that using -dumpstream is usually a better way to copy DVD titles in the first place (see the examples).

-dvdangle <angle ID> (DVD only)

Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell MPlayer which angles to use (default: 1).

-edl <filename> (EDL only)

Enables edit decision list (EDL) actions during playback. Video will be skipped over and audio will be muted and unmuted according to the entries in the given file. See DOCS/:HTML/:en/:edl.html for details on how to use this.

-forceidx

Force index rebuilding. Useful for files with broken index (A/:V desync, etc). This will enable seeking in files where seeking was not possible. You can fix the index permanently with MEncoder (see the documentation).

NOTE: This option only works if the underlying media supports seeking (i.e. not with stdin, pipe, etc).

-fps <float value>

Override video framerate. Useful if the original value is wrong or missing.

-frames <number>

Play/:convert only first <number> frames, then quit.

-hr-mp3-seek (MP3 only)

Hi-res MP3 seeking. Enabled when playing from an external MP3 file, as we need to seek to the very exact position to keep A/:V sync. Can be slow especially when seeking backwards since it has to rewind to the beginning to find an exact frame position.

-idx (also see -forceidx)

Rebuilds index of files if no index was found, allowing seeking. Useful with broken/:incomplete downloads, or badly created files.

NOTE: This option only works if the underlying media supports seeking (i.e. not with stdin, pipe, etc).

-ipv4-only-proxy (network only)

Skip the proxy for IPv6 addresses. It will still be used for IPv4 connections.

-loadidx <index file>

The file from which to read the video index data saved by -saveidx. This index will be used for seeking, overriding any index data contained in the AVI itself. MPlayer will not prevent you from loading an index file generated from a different AVI, but this is sure to cause unfavorable results.

NOTE: This option is obsolete now that MPlayer has OpenDML support.

-mc <seconds/:frame>

maximum A-V sync correction per frame (in seconds)

-mf <option1:option2:...>

Used when decoding from multiple PNG or JPEG files. Available options are: output width (default: autodetect) output height (default: autodetect) output fps (default: 25) input file type (available: jpeg, png, tga, sgi)

-ni (AVI only)

Force usage of non-interleaved AVI parser (fixes playback of some bad AVI files).

-nobps (AVI only)

Do not use average byte/:second value for A-V sync. Helps with some AVI files with broken header.

-noextbased

Disables extension-based demuxer selection. By default, when the file type (demuxer) cannot be detected reliably (the file has no header or it is not reliable enough), the filename extension is used to select the demuxer. Always falls back on content-based demuxer selection.

-passwd <password> (also see -user) (network only)

Specify password for HTTP authentication.

-prefer-ipv4 (network only)

Use IPv4 on network connections. Falls back on IPv6 automatically.

-prefer-ipv6 (IPv6 network only)

Use IPv6 on network connections. Falls back on IPv4 automatically.

-rawaudio <option1:option2:...>

This option lets you play raw audio files. You have to use -demuxer rawaudio as well. It may also be used to play audio CDs which are not 44kHz 16-bit stereo. For playing raw AC3 streams use -rawaudio format=0x2000 -demuxer rawaudio. Available options are: number of channels rate in samples per second sample size in bytes bitrate for rawaudio files fourcc in hex

-rawvideo <option1:option2:...>

This option lets you play raw video files. You have to use -demuxer rawvideo as well. Available options are: rate in frames per second (default: 25.0) set standard image size image width in pixels image height in pixels set colorspace colorspace (fourcc) in hex frame size in Bytes EXAMPLE: Play the famous "foreman" sample video. Play a raw YUV sample.

-rtsp-stream-over-tcp (LIVE555 only)

Used with 'rtsp://' URLs to specify that the resulting incoming RTP and RTCP packets be streamed over TCP (using the same TCP connection as RTSP). This option may be useful if you have a broken internet connection that does not pass incoming UDP packets (see http://www.live555.com/:mplayer/).

-saveidx <filename>

Force index rebuilding and dump the index to <filename>. Currently this only works with AVI files.

NOTE: This option is obsolete now that MPlayer has OpenDML support.

-sb <byte position> (also see -ss)

Seek to byte position. Useful for playback from CD-ROM images or VOB files with junk at the beginning.

-speed <0.01-100>

Slow down or speed up playback by the factor given as parameter. Not guaranteed to work correctly with -oac copy.

-srate <Hz>

Selects the output sample rate to be used (of course sound cards have limits on this). If the sample frequency selected is different from that of the current media, the resample or lavcresample audio filter will be inserted into the audio filter layer to compensate for the difference. The type of resampling can be controlled by the -af-adv option. The default is fast resampling that may cause distortion.

-ss <time> (also see -sb)

Seek to given time position. EXAMPLE: Seeks to 56 seconds. Seeks to 1 hour 10 min.

-tskeepbroken

Tells MPlayer not to discard TS packets reported as broken in the stream. Sometimes needed to play corrupted MPEG-TS files.

-tsprobe <byte position>

When playing an MPEG-TS stream, this option lets you specify how many bytes in the stream you want MPlayer to search for the desired audio and video IDs.

-tsprog <1-65534>

When playing an MPEG-TS stream, you can specify with this option which program (if present) you want to play. Can be used with -vid and -aid.

-tv <option1:option2:...> (TV only)

This option tunes various properties of the TV capture module. For watching TV with MPlayer, use 'tv://' or 'tv://<channel_number>' or even 'tv://<channel_name> (see option channels for channel_name below) as a movie URL. Available options are: no sound available: dummy, v4l, v4l2, bsdbt848 Specify TV device (default: /dev/:video0). Specify input (default: 0 (TV), see console output for available inputs). Specify the frequency to set the tuner to (e.g. 511.250). Not compatible with the channels parameter. Specify the output format of the tuner with a preset value supported by the V4L driver (yv12, rgb32, rgb24, rgb16, rgb15, uyvy, yuy2, i420) or an arbitrary format given as hex value. Try outfmt=help for a list of all available formats. output window width output window height framerate at which to capture video (frames per second) maximum size of the capture buffer in megabytes (default: dynamical) For bsdbt848 and v4l, PAL, SECAM, NTSC are available. For v4l2, see the console output for a list of all available norms, also see the normid option below. Sets the TV norm to the given numeric ID. The TV norm depends on the capture card. See the console output for a list of available TV norms. Set tuner to <value> channel. available: europe-east, europe-west, us-bcast, us-cable, etc Set names for channels. Use _ for spaces in names (or play with quoting ;-). The channel names will then be written using OSD, and the slave commands tv_step_channel, tv_set_channel and tv_last_channel will be usable for a remote control (see LIRC). Not compatible with the frequency parameter.

NOTE: The channel number will then be the position in the 'channels' list, beginning with 1.

EXAMPLE: tv://1, tv://TV1, tv_set_channel 1, tv_set_channel TV1 Set the image equalizer on the card. Set audio capture bitrate. Capture audio even if there are no audio sources reported by v4l. Capture from ALSA. Choose an audio mode: 0: mono

1: stereo

2: language 1

3: language 2 By default, the count of recorded audio channels is determined automatically by querying the audio mode from the TV card. This option allows forcing stereo/:mono recording regardless of the amode option and the values returned by v4l. This can be used for troubleshooting when the TV card is unable to report the current audio mode. Set an audio device. <value> should be /dev/:xxx for OSS and a hardware ID for ALSA. You must replace any ':' by a '.' in the hardware ID for ALSA. Choose an audio output of the capture card, if it has more than one. These options set parameters of the mixer on the video capture card. They will have no effect, if your card does not have one. For v4l2 50 maps to the default value of the control, as reported by the driver. A value of 0 means capture and buffer audio and video together (default for MEncoder). A value of 1 (default for MPlayer) means to do video capture only and let the audio go through a loopback cable from the TV card to the sound card. Use hardware MJPEG compression (if the card supports it). When using this option, you do not need to specify the width and height of the output window, because MPlayer will determine it automatically from the decimation value (see below). choose the size of the picture that will be compressed by hardware MJPEG compression: 1: full size 704x576 PAL 704x480 NTSC

2: medium size 352x288 PAL 352x240 NTSC

4: small size 176x144 PAL 176x120 NTSC Choose the quality of the JPEG compression (< 60 recommended for full size).

Display DVD Closed Caption (CC) subtitles. These are not the VOB subtitles, these are special ASCII subtitles for the hearing impaired encoded in the VOB userdata stream on most region 1 DVDs. CC subtitles have not been spotted on DVDs from other regions so far.

-subcp <codepage> (iconv only)

If your system supports iconv(3), you can use this option to specify the subtitle codepage. EXAMPLE: -subcp latin2

-subcp cp1250

-subcp enca:<language>:<fallback codepage> (ENCA only)

You can specify your language using a two letter language code to make ENCA detect the codepage automatically. If unsure, enter anything and watch mplayer -v output for available languages.

Use a mixer device different from the default /dev/:mixer. For ALSA this is the mixer name.

-mixer-channel <mixer line>[,mixer index] (-ao oss and -ao alsa only)

This option will tell MPlayer to use a different channel for controlling volume than the default PCM. Options for OSS include vol, pcm, line. For a complete list of options look for SOUND_DEVICE_NAMES in /usr/:include/:linux/:soundcard.h. For ALSA you can use the names e.g. alsamixer displays, like Master, Line, PCM.

NOTE: ALSA mixer channel names followed by a number must be specified in the <name,number> format, i.e. a channel labeled 'PCM 1' in alsamixer must be converted to PCM,1.

-softvol

Force the use of the software mixer, instead of using the sound card mixer.

-softvol-max <10.0-10000.0>

Set the maximum amplification level in percent (default: 110). A value of 200 will allow you to adjust the volume up to a maximum of double the current level. With values below 100 the initial volume (which is 100%) will be above the maximum, which e.g. the OSD cannot display correctly.

-volstep <0-100>

Use the _NETWM_STATE_FULLSCREEN hint if available. Use the _WIN_LAYER hint with the default layer. Use the _WIN_LAYER hint with the given layer number. Force NETWM style. Do not set fullscreen window layer. Use _NETWM_STATE_STAYS_ON_TOP hint if available. EXAMPLE: Default order, will be used as a fallback if incorrect or unsupported modes are specified. Fixes fullscreen switching on OpenBox 1.x.

-geometry x[%][:y[%]] or [WxH][+x+y]

Adjust where the output is on the screen initially. The x and y specifications are in pixels measured from the top-left of the screen to the top-left of the image being displayed, however if a percentage sign is given after the argument it turns the value into a percentage of the screen size in that direction. It also supports the standard X11 -geometry option format. If an external window is specified using the -wid option, then the x and y coordinates are relative to the top-left corner of the window rather than the screen.

NOTE: This option is only supported by the x11, xmga, xv, xvmc, xvidix, gl, gl2, directx and tdfxfb video output drivers. EXAMPLE: Places the window at x=50, y=40.

-nograbpointer

Do not grab the mouse pointer after a video mode change (-vm). Useful for multihead setups.

-nokeepaspect

Do not keep window aspect ratio when resizing windows. Only works with the x11, xv, xmga, xvidix, directx video output drivers. Furthermore under X11 your window manager has to honor window aspect hints.

Makes the player window stay on top of other windows. Supported by video output drivers which use X11, except SDL, as well as directx, macosx, quartz, ggi and gl2.

-panscan <0.0-1.0>

Enables pan-and-scan functionality (cropping the sides of e.g. a 16:9 movie to make it fit a 4:3 display without black bands). The range controls how much of the image is cropped. Only works with the xv, xmga, mga, gl, gl2, quartz, macosx and xvidix video output drivers.

-panscanrange <-19.0-99.0> (experimental)

Change the range of the pan-and-scan functionality (default: 1). Positive values mean multiples of the default range. Negative numbers mean you can zoom in up to a factor of -panscanrange+1. E.g. -panscanrange -3 allows a zoom factor of up to 4. This feature is experimental. Do not report bugs unless you are using -vo gl.

-refreshrate <Hz>

Set the monitor refreshrate in Hz. Currently only supported by -vo directx combined with the -vm option.

-rootwin

Play movie in the root window (desktop background). Desktop background images may cover the movie window, though. Only works with the x11, xv, xmga, xvidix, quartz, macosx and directx video output drivers.

-saturation <-100-100>

Adjust the saturation of the video signal (default: 0). You can get grayscale output with this option. Not supported by all video output drivers.

-screenh <pixels>

Specify the vertical screen resolution for video output drivers which do not know the screen resolution like fbdev, x11 and TVout.

-screenw <pixels>

Specify the horizontal screen resolution for video output drivers which do not know the screen resolution like fbdev, x11 and TVout.

-stop-xscreensaver (X11 only)

Turns off xscreensaver at startup and turns it on again on exit.

-vm

Try to change to a different video mode. Supported by the dga, x11, xv, sdl and directx video output drivers. If used with the directx video output driver the -screenw, -screenh, -bpp and -refreshrate options can be used to set the new display mode.

-vsync

Enables VBI for the vesa, dfbmga and svga video output drivers.

-wid <window ID> (also see -guiwid) (X11, OpenGL and DirectX only)

This tells MPlayer to attach to an existing window. Useful to embed MPlayer in a browser (e.g. the plugger extension).

-xineramascreen <0-...>

In Xinerama configurations (i.e. a single desktop that spans across multiple displays) this option tells MPlayer which screen to display the movie on.

-zrbw (-vo zr only)

-zrcrop <[width]x[height]+[x offset]+[y offset]> (-vo zr only)

Select a part of the input image to display, multiple occurrences of this option switch on cinerama mode. In cinerama mode the movie is distributed over more than one TV (or beamer) to create a larger image. Options appearing after the n-th -zrcrop apply to the n-th MJPEG card, each card should at least have a -zrdev in addition to the -zrcrop. For examples, see the output of -zrhelp and the Zr section of the documentation.

-zrdev <device> (-vo zr only)

Specify the device special file that belongs to your MJPEG card, by default the zr video output driver takes the first v4l device it can find.

-zrfd (-vo zr only)

If the movie is smaller than the TV screen, this option specifies the x offset from the upper-left corner of the TV screen (default: centered).

-zrydoff <y display offset> (-vo zr only)

If the movie is smaller than the TV screen, this option specifies the y offset from the upper-left corner of the TV screen (default: centered).

Video output drivers are interfaces to different video output facilities. The syntax is:

-vo <driver1[:suboption1[=value]:...],driver2,...[,]>

Specify a priority list of video output drivers to be used.

If the list has a trailing ',' MPlayer will fall back on drivers not contained in the list. Suboptions are optional and can mostly be omitted.

NOTE: See -vo help for a list of compiled-in video output drivers. EXAMPLE: Try the Matrox X11 driver, then the Xv driver, then others. Uses the DirectX driver with acceleration features turned off. Available video output drivers are:

xv (X11 only)

Uses the XVideo extension of XFree86 4.x to enable hardware accelerated playback. If you cannot use a hardware specific driver, this is probably the best option. For information about what colorkey is used and how it is drawn run MPlayer with -v option and look out for the lines tagged with [xv common] at the beginning. Select a specific XVideo port. Select the source from which the colorkey is taken (default: cur). The default takes the colorkey currently set in Xv. Use but do not set the colorkey from MPlayer (use -colorkey option to change it). Same as use but also sets the supplied colorkey. Sets the colorkey drawing method (default: man). Draw the colorkey manually (reduces flicker in some cases). Set the colorkey as window background. Let Xv draw the colorkey.

x11 (X11 only)

Shared memory video output driver without hardware acceleration that works whenever X11 is present.

xover (X11 only)

Adds X11 support to all overlay based video output drivers. Currently only supported by tdfx_vid. Select the driver to use as source to overlay on top of X11.

xvmc (X11 with -vc ffmpeg12mc only)

Video output driver that uses the XvMC (X Video Motion Compensation) extension of XFree86 4.x to speed up MPEG-1/2 and VCR2 decoding. Select a specific XVideo port. Disables image display. Necessary for proper benchmarking of drivers that change image buffers on monitor retrace only (nVidia). Default is not to disable image display (nobenchmark). Queue frames for display to allow more parallel work of the video hardware. May add a small (not noticeable) constant A/:V desync (default: noqueue). Use sleep function while waiting for rendering to finish (not recommended on Linux) (default: nosleep). Same as -vo xv:ck (see -vo xv). Same as -vo xv:ck-method (see -vo xv).

dga (X11 only)

Play video through the XFree86 Direct Graphics Access extension. Considered obsolete.

sdl (SDL only)

Highly platform independent SDL (Simple Directmedia Layer) library video output driver. Since SDL uses its own X11 layer, MPlayer X11 options do not have any effect on SDL. Explicitly choose the SDL driver to use. Use XVideo through the sdl video output driver (default: forcexv). Use hardware accelerated scaler (default: hwaccel).

vidix

VIDIX (VIDeo Interface for *niX) is an interface to the video acceleration features of different graphics cards. Very fast video output driver on cards that support it. Explicitly choose the VIDIX subdevice driver to use. Available subdevice drivers are cyberblade_vid.so, mach64_vid.so, mga_crtc2_vid.so, mga_vid.so, nvidia_vid.so, pm3_vid.so, radeon_vid.so, rage128_vid.so, sis_vid.so and unichrome_vid.so.

xvidix (X11 only)

X11 frontend for VIDIX same as vidix

cvidix

Generic and platform independent VIDIX frontend, can even run in a text console with nVidia cards. same as vidix

winvidix (Windows only)

Windows frontend for VIDIX same as vidix

directx (Windows only)

Video output driver that uses the DirectX interface. Turns off hardware acceleration. Try this option if you have display problems.

quartz (Mac OS X only)

Mac OS X Quartz video output driver. Under some circumstances, it might be more efficient to force a packed YUV output format, with e.g. -vf format=yuy2. Choose the display device to use in fullscreen. Specify the fullscreen resolution (useful on slow systems).

macosx (Mac OS X 10.4 or 10.3.9 with QuickTime 7)

Mac OS X CoreVideo video output driver Choose the display device to use in fullscreen.

fbdev (Linux only)

Uses the kernel framebuffer to play video. Explicitly choose the fbdev device name to use (e.g. /dev/:fb0) or the name of the VIDIX subdevice if the device name starts with 'vidix' (e.g. 'vidixsis_vid' for the sis driver).

fbdev2 (Linux only)

Uses the kernel framebuffer to play video, alternative implementation. Explicitly choose the fbdev device name to use (default: /dev/:fb0).

vesa

Very general video output driver that should work on any VESA VBE 2.0 compatible card. Turns on DGA mode. Turns off DGA mode. Activate the NeoMagic TV out and set it to PAL norm. Activate the NeoMagic TV out and set it to NTSC norm. Use the VIDIX driver. Activate the Linux Video Overlay on top of VESA mode.

svga

Play video using the SVGA library. Specify video mode to use. The mode can be given in a <width>x<height>x<colors> format, e.g. 640x480x16M or be a graphics mode number, e.g. 84. Draw OSD into black bands below the movie (slower). Use only native drawing functions. This avoids direct rendering, OSD and hardware acceleration. Force frame switch on vertical retrace. Usable only with -double. It has the same effect as the -vsync option. Try to select a video mode with square pixels. Use svga with VIDIX.

gl

OpenGL video output driver, simple version. Video size must be smaller than the maximum texture size of your OpenGL implementation. Intended to work even with the most basic OpenGL implementations, but also makes use of newer extensions, which allow support for more colorspaces and direct rendering. Please use -dr if it works with your OpenGL implementation, since for higher resolutions this provides a big speedup. The code performs very few checks, so if a feature does not work, this might be because it is not supported by your card/OpenGL implementation even if you do not get any error message. Use glxinfo or a similar tool to display the supported OpenGL extensions. Enables support for more (RGB and BGR) color formats (default: enabled). Needs OpenGL version >= 1.2. Number of lines copied to texture in one piece (default: 4). 0 for whole image.

NOTE: If YUV colorspace is used (see yuv suboption), special rules apply: If the decoder uses slice rendering (see -noslices), this setting has no effect, the size of the slices as provided by the decoder is used.

If the decoder does not use slice rendering, the default is 16. Enable or disable support for OSD rendering via OpenGL (default: enabled). This option is for testing; to disable the OSD use -osdlevel 0 instead. Changes the way the OSD behaves when the size of the window changes (default: disabled). When enabled behaves more like the other video output drivers, which is better for fixed-size fonts. Disabled looks much better with FreeType fonts and uses the borders in fullscreen mode. Enable or disable aspect scaling and pan-and-scan support (default: enabled). Disabling might increase speed. Select usage of rectangular textures which saves video RAM, but often is slower (default: 0). 0: Use power-of-two textures (default).

1: Use the GL_ARB_texture_rectangle extension.

2: Use the GL_ARB_texture_non_power_of_two extension. In some cases only supported in software and thus very slow. Call glFinish() before swapping buffers. Slower but in some cases more correct output (default: disabled). Minimum interval between two buffer swaps, counted in displayed frames (default: 1). 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC. Values below 0 will leave it at the system default. This limits the framerate to (horizontal refresh rate / n). Requires GLX_SGI_swap_control support to work. With some (most/all?) implementations this only works in fullscreen mode. Select the type of YUV to RGB conversion. 0: Use software conversion (default). Compatible with all OpenGL versions. Provides brightness, contrast and saturation control.

1: Use register combiners. This uses an nVidia-specific extension (GL_NV_register_combiners). At least three texture units are needed. Provides saturation and hue control.

2: Use a fragment program. Needs the GL_ARB_fragment_program extension and at least three texture units. Provides brightness, contrast, saturation and hue control.

3: Use a fragment program using the POW instruction. Needs the GL_ARB_fragment_program extension and at least three texture units. Provides brightness, contrast, saturation, hue and gamma control. Gamma can also be set independently for red, green and blue. Method 4 is usually faster.

4: Use a fragment program with additional lookup. Needs the GL_ARB_fragment_program extension and at least four texture units. Provides brightness, contrast, saturation, hue and gamma control. Gamma can also be set independently for red, green and blue.

5: Use ATI-specific method (for older cards). This uses an ATI-specific extension (GL_ATI_fragment_shader - not GL_ARB_fragment_shader!). At least three texture units are needed. Provides saturation and hue control. Load a custom fragment program from <filename>. See TOOLS/edgedect.fp for an example. Load a custom "gamma ramp" texture from <filename>. This can be used in combination with yuv=4 or with the customprog option.

gl2

OpenGL video output driver, second generation. Supports OSD and videos larger than the maximum texture size. same as gl (default: enabled) Select the type of YUV to RGB conversion. If set to anything except 0 OSD will be disabled and brightness, contrast and gamma setting is only available via the global X server settings. Apart from this the values have the same meaning as for -vo gl.

null

aa

ASCII art video output driver that works on a text console. You can get a list and an explanation of available suboptions executing mplayer -vo aa:help

caca

Color ASCII art video output driver that works on a text console.

bl

ggi

GGI graphics system video output driver Explicitly choose the GGI driver to use. Replace any ',' that would appear in the driver string by a '.'.

directfb

Play video using the DirectFB library. Use the DirectFB instead of the MPlayer keyboard code (default: enabled). Double and triple buffering give best results if you want to avoid tearing issues. Triple buffering is more efficient than double buffering as it does not block MPlayer while waiting for the vertical retrace. Single buffering should be avoided (default: single). Control the output order for interlaced frames (default: disabled). Valid values are top = top fields first, bottom = bottom fields first. This option does not have any effect on progressive film material like most MPEG movies are. You need to enable this option if you have tearing issues/:unsmooth motions watching interlaced film material. Will force layer with ID N for playback (default: -1 - auto). Specify a parameter list for DirectFB.

dfbmga

Matrox G400/:G450/:G550 specific video output driver that uses the DirectFB library to make use of special hardware features. Enables CRTC2 (second head), displaying video independently of the first head. same as directfb (default: disabled) same as directfb (default: triple) same as directfb Enable the use of the Matrox BES (backend scaler) (default: disabled). Gives very good results concerning speed and output quality as interpolated picture processing is done in hardware. Works only on the primary head. Make use of the Matrox sub picture layer to display the OSD (default: enabled). Turn on TV-out on the second head (default: enabled). The output quality is amazing as it is a full interlaced picture with proper sync to every odd/:even field. Will set the TV norm of the Matrox card without the need for modifying /etc/:directfbrc (default: disabled). Valid norms are pal = PAL, ntsc = NTSC. Special norm is auto (auto-adjust using PAL/:NTSC) because it decides which norm to use by looking at the framerate of the movie.

mga (Linux only)

Matrox specific video output driver that makes use of the YUV back end scaler on Gxxx cards through a kernel module. If you have a Matrox card, this is the fastest option. Explicitly choose the Matrox device name to use (default: /dev/:mga_vid).

This driver employs the tdfx framebuffer driver to play movies with YUV acceleration on 3dfx cards. FIXME: It' ok the difference between 3dfx, tdfxfb and tdfx_vid? Explicitly choose the fbdev device name to use (default: /dev/:fb0).

tdfx_vid (Linux only)

3dfx specific video output driver. This driver directly uses the tdfx_vid kernel module. FIXME: It' ok the difference between 3dfx, tdfxfb and tdfx_vid? Explicitly choose the device name to use (default: /dev/:tdfx_vid).

2: Auto-adjust using PAL/:PAL-60.

3: PAL

4: PAL-60

5: NTSC Specifies the device number to use if you have more than one em8300 card.

yuv4mpeg

Transforms the video stream into a sequence of uncompressed YUV 4:2:0 images and stores it in a file (default: ./stream.yuv). The format is the same as the one employed by mjpegtools, so this is useful if you want to process the video with the mjpegtools suite. It supports the YV12, RGB (24 bpp) and BGR (24 bpp) format. You can combine it with the -fixed-vo option to concatenate files with the same dimensions and fps value. Write the output as interlaced frames, top field first. Write the output as interlaced frames, bottom field first. Write the output to <filename> instead of the default stream.yuv. NOTE: If you do not specify any option the output is progressive (i.e. not interlaced).

gif89a

Output each frame into a single animated GIF file in the current directory. It supports only RGB format with 24 bpp and the output is converted to 256 colors. Float value to specify framerate (default: 5.0). Specify the output filename (default: ./out.gif). NOTE: You must specify the framerate before the filename or the framerate will be part of the filename. EXAMPLE: mplayer video.nut -vo gif89a:fps=15.0:filename=test.gif

Also see pnm(5), ppm(5) and pgm(5). Write PPM files (default). Write PGM files. Write PGMYUV files. PGMYUV is like PGM, but it also contains the U and V plane, appended at the bottom of the picture. Write PNM files in raw mode (default). Write PNM files in ASCII mode. Specify the directory to save the PNM files to (default: ./). Create numbered subdirectories with the specified prefix to save the files in instead of the current directory. Maximum number of files to be saved per subdirectory. Must be equal to or larger than 1 (default: 1000).

tga

Output each frame into a Targa file in the current directory. Each file takes the frame number padded with leading zeros as name. The purpose of this video output driver is to have a simple lossless image writer to use without any external library. It supports the BGR[A] color format, with 15, 24 and 32 bpp. You can force a particular format with the format video filter. EXAMPLE: mplayer video.nut -vf format=bgr15 -vo tga

-ac <[-|+]codec1,[-|+]codec2,...[,]>

Specify a priority list of audio codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. Use a '+' before the codec name to force it, this will likely crash! If the list has a trailing ',' MPlayer will fall back on codecs not contained in the list.

NOTE: See -ac help for a full list of available codecs. EXAMPLE: Force the l3codeca.acm MP3 codec. Try libmad first, then fall back on others. Try hardware AC3 passthrough, software AC3, then others. Skip FFmpeg's MP3 decoder.

-af-adv <force=(0-7):list=(filters)> (also see -af)

Specify advanced audio filter options: Forces the insertion of audio filters to one of the following: 0: Use completely automatic filter insertion.

1: Optimize for accuracy (default).

2: Optimize for speed. Warning: Some features in the audio filters may silently fail, and the sound quality may drop.

6: Use automatic insertion of filters according to 2 above, but use floating point processing when possible.

7: Use no automatic insertion of filters according to 3 above, and use floating point processing when possible. Same as -af.

-afm <driver1,driver2,...>

Specify a priority list of audio codec families to be used, according to their codec name in codecs.conf. Falls back on the default codecs if none of the given codec families work.

NOTE: See -afm help for a full list of available codec families. EXAMPLE: Try FFmpeg's libavcodec codecs first. Try Win32 codecs first.

-aspect <ratio> (also see -zoom)

Override movie aspect ratio, in case aspect information is incorrect or missing in the file being played. EXAMPLE: -aspect 4:3 or -aspect 1.3333

-aspect 16:9 or -aspect 1.7777

-noaspect

Disable automatic movie aspect ratio compensation.

-flip

Flip image upside-down.

-lavdopts <option1:option2:...> (DEBUG CODE)

Specify libavcodec decoding parameters. EXAMPLE: -lavdopts bug=1 Available options are: Only use bit-exact algorithms in all decoding steps (for codec testing). Manually work around encoder bugs. 0: nothing

2 (msmpeg4v3): some old lavc generated msmpeg4v3 files (no autodetection)

4 (mpeg4): XviD interlacing bug (autodetected if fourcc==XVIX)

8 (mpeg4): UMP4 (autodetected if fourcc==UMP4)

512 (mpeg4): direct-qpel-blocksize bug (autodetected per fourcc/:version)

1024 (mpeg4): edge padding bug (autodetected per fourcc/:version) Display debugging information.

0: disabled

1: picture info

2: rate control

4: bitstream

8: macroblock (MB) type

16: per-block quantization parameter (QP)

32: motion vector

0x0040: motion vector visualization (use -noslices)

0x0080: macroblock (MB) skip

0x0100: startcode

0x0200: PTS

0x0400: error resilience

0x0800: memory management control operations (H.264)

0x1000: bugs

0x2000: Visualize quantization parameter (QP), lower QP are tinted greener.

0x4000: Visualize block types. Set error concealment strategy. 1: Use strong deblock filter for damaged MBs.

2: iterative motion vector (MV) search (slow)

3: all (default) Set error resilience strategy.

0: disabled

1: careful (Should work with broken encoders.)

2: normal (default) (Works with compliant encoders.)

3: aggressive (More checks, but might cause problems even for valid bitstreams.)

4: very aggressive Enable optimizations which do not comply to the specification and might potentially cause problems, like simpler dequantization, assuming use of the default quantization matrix, assuming YUV 4:2:0 and skipping a few checks to detect damaged bitstreams. grayscale only decoding (a bit faster than with color) For best decoding quality use the same IDCT algorithm for decoding and encoding. This may come at a price in accuracy, though. Decode at lower resolutions. Low resolution decoding is not supported by all codecs, and it will often result in ugly artifacts. This is not a bug, but a side effect of not decoding at full resolution.

0: disabled

1: 1/2 resolution

2: 1/4 resolution

3: 1/8 resolution If <w> is specified lowres decoding will be used only if the width of the video is major than or equal to <w>. Skip the given number of macroblock rows at the bottom. Skip the given number of macroblock rows at the top. Skips the loop filter (AKA deblocking) during H.264 decoding. Since the filtered frame is supposed to be used as reference for decoding dependant frames this has a worse effect on quality than not doing deblocking on e.g. MPEG-2 video. But at least for high bitrate HDTV this provides a big speedup with no visible quality loss. <skipvalue> can be either one of the following:

none: Never skip.

default: Skip useless processing steps (e.g. 0 size packets in AVI).

nonref: Skip frames that are not referenced (i.e. not used for decoding other frames, the error cannot "build up").

bidir: Skip B-Frames.

nonkey: Skip all frames except keyframes.

all: Skip all frames. Skips the IDCT step. This degrades quality a lot of in almost all cases (see skiploopfilter for available skip values). Skips decoding of frames completely. Big speedup, but jerky motion and sometimes bad artifacts (see skiploopfilter for available skip values). number of threads to use for decoding (default: 1) Visualize motion vectors.

0: disabled

1: Visualize forward predicted MVs of P-frames.

2: Visualize forward predicted MVs of B-frames.

4: Visualize backward predicted MVs of B-frames. Prints some statistics and stores them in ./vstats_*.log.

-noslices

Disable drawing video by 16-pixel height slices/:bands, instead draws the whole frame in a single run. May be faster or slower, depending on card/:cache. It has effect only with libmpeg2 and libavcodec codecs.

-nosound

Do not play/:encode sound. Useful for benchmarking.

-novideo

Do not play/:encode video. In many cases this will not work, use -vc null -vo null instead.

-oldpp <quality> (OpenDivX only) (OBSOLETE)

Use the OpenDivX postprocessing code instead of the internal one. Superseded by -pp, the internal postprocessing offers better quality and performance. The valid range of -oldpp values varies by codec, it is mostly 0-6, where 0=disable, 6=slowest/:best.

-pp <quality> (also see -vf pp)

Set the DLL postprocess level. This option is no longer usable with -vf pp. It only works with Win32 DirectShow DLLs with internal postprocessing routines. The valid range of -pp values varies by codec, it is mostly 0-6, where 0=disable, 6=slowest/:best.

-pphelp (also see -vf pp)

Show a summary about the available postprocess filters and their usage.

-ssf <mode>

Specifies software scaler parameters. EXAMPLE: -vf scale -ssf lgb=3.0 gaussian blur filter (luma) gaussian blur filter (chroma) sharpen filter (luma) sharpen filter (chroma) chroma horizontal shifting chroma vertical shifting

-stereo <mode>

Select type of MP2/:MP3 stereo output. stereo left channel right channel

-sws <software scaler type> (also see -vf scale and -zoom)

Specify the software scaler algorithm to be used with the -zoom option. This affects video output drivers which lack hardware acceleration, e.g. x11. Available types are: fast bilinear bilinear bicubic (good quality) (default) experimental nearest neighbor (bad quality) area luma bicubic / chroma bilinear gauss sincR lanczos natural bicubic spline NOTE: Some -sws options are tunable. The description of the scale video filter has further information.

-vc <[-|+]codec1,[-|+]codec2,...[,]>

Specify a priority list of video codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. Use a '+' before the codec name to force it, this will likely crash! If the list has a trailing ',' MPlayer will fall back on codecs not contained in the list.

NOTE: See -vc help for a full list of available codecs. EXAMPLE: Force Win32/:VfW DivX codec, no fallback. Try divx4linux codec first, then fall back on others. Skip Win32 DivX codecs. Try libavcodec's MPEG-1/2 codec, then libmpeg2, then others.

-vfm <driver1,driver2,...>

Specify a priority list of video codec families to be used, according to their names in codecs.conf. Falls back on the default codecs if none of the given codec families work.

NOTE: See -vfm help for a full list of available codec families. EXAMPLE: Try the libavcodec, then Directshow, then VfW codecs and fall back on others, if they do not work. Try XAnim codecs first.

-x <x> (also see -zoom) (MPlayer only)

Scale image to width <x> (if software/:hardware scaling is available). Disables aspect calculations.

-xvidopts <option1:option2:...>

Specify additional parameters when decoding with XviD.

NOTE: Since libavcodec is faster than XviD you might want to use the libavcodec postprocessing filter (-vf pp) and decoder (-vfm ffmpeg) instead. XviD's internal postprocessing filters: chroma deblock filter luma deblock filter luma deringing filter chroma deringing filter Adds artificial film grain to the video. May increase perceived quality, while lowering true quality. rendering methods: Activate direct rendering method 2. Deactivate direct rendering method 2.

-xy <value> (also see -zoom)

Scale image by factor <value>. Set width to value and calculate height to keep correct aspect ratio.

-y <y> (also see -zoom) (MPlayer only)

Scale image to height <y> (if software/:hardware scaling is available). Disables aspect calculations.

-zoom

Allow software scaling, where available. This will allow scaling with output drivers (like x11, fbdev) that do not support hardware scaling where MPlayer disables scaling by default for performance reasons.

Audio filters allow you to modify the audio stream and its properties. The syntax is:

-af <filter1[=parameter1:parameter2:...],filter2,...>

Setup a chain of audio filters.

NOTE: To get a full list of available audio filters, see -af help.

Available filters are:

resample[=srate[:sloppy[:type]]]

Changes the sample rate of the audio stream. Can be used if you have a fixed frequency sound card or if you are stuck with an old sound card that is only capable of max 44.1kHz. This filter is automatically enabled if necessary. It only supports 16-bit integer and float in native-endian format as input.

NOTE: With MEncoder, you need to also use -srate <srate>. output sample frequency in Hz. The valid range for this parameter is 8000 to 192000. If the input and output sample frequency are the same or if this parameter is omitted the filter is automatically unloaded. A high sample frequency normally improves the audio quality, especially when used in combination with other filters. Allow (1) or disallow (0) the output frequency to differ slightly from the frequency given by <srate> (default: 1). Can be used if the startup of the playback is extremely slow. Selects which resampling method to use. 0: linear interpolation (fast, poor quality especially when upsampling)

1: polyphase filterbank and integer processing

2: polyphase filterbank and floating point processing (slow, best quality) EXAMPLE: would set the output frequency of the resample filter to 44100Hz using exact output frequency scaling and linear interpolation.

lavcresample[=srate[:length[:linear[:count[:cutoff]]]]]

Changes the sample rate of the audio stream to an integer <srate> in Hz. It only supports the 16-bit native-endian format.

NOTE: With MEncoder, you need to also use -srate <srate>. the output sample rate length of the filter with respect to the lower sampling rate (default: 16) if 1 then filters will be linearly interpolated between polyphase entries log2 of the number of polyphase entries (..., 10->1024, 11->2048, 12->4096, ...) (default: 10->1024) cutoff frequency (0.0-1.0), default set depending upon filter length

sweep[=speed]

Produces a sine sweep. Sine function delta, use very low values to hear the sweep.

hrtf[=flag]

Head-related transfer function: Converts multichannel audio to 2 channel output for headphones, preserving the spatiality of the sound.

equalizer=[g1:g2:g3:...:g10]

10 octave band graphic equalizer, implemented using 10 IIR band pass filters. This means that it works regardless of what type of audio is being played back. The center frequencies for the 10 bands are: If the sample rate of the sound being played is lower than the center frequency for a frequency band, then that band will be disabled. A known bug with this filter is that the characteristics for the uppermost band are not completely symmetric if the sample rate is close to the center frequency of that band. This problem can be worked around by upsampling the sound using the resample filter before it reaches this filter. floating point numbers representing the gain in dB for each frequency band (-12-12) EXAMPLE: Would amplify the sound in the upper and lower frequency region while canceling it almost completely around 1kHz.

channels=nch[:nr:from1:to1:from2:to2:from3:to3:...]

Can be used for adding, removing, routing and copying audio channels. If only <nch> is given the default routing is used, it works as follows: If the number of output channels is bigger than the number of input channels empty channels are inserted (except mixing from mono to stereo, then the mono channel is repeated in both of the output channels). If the number of output channels is smaller than the number of input channels the exceeding channels are truncated. number of output channels (1-6) number of routes (1-6) Pairs of numbers between 0 and 5 that define where to route each channel. EXAMPLE: Would change the number of channels to 4 and set up 4 routes that swap channel 0 and channel 1 and leave channel 2 and 3 intact. Observe that if media containing two channels was played back, channels 2 and 3 would contain silence but 0 and 1 would still be swapped. Would change the number of channels to 6 and set up 4 routes that copy channel 0 to channels 0 to 3. Channel 4 and 5 will contain silence.

format[=format] (also see -format)

Convert between different sample formats. Automatically enabled when needed by the sound card or another filter. Sets the desired format. The general form is 'sbe', where 's' denotes the sign (either 's' for signed or 'u' for unsigned), 'b' denotes the number of bits per sample (16, 24 or 32) and 'e' denotes the endianness ('le' means little-endian, 'be' big-endian and 'ne' the endianness of the computer MPlayer is running on). Valid values (amongst others) are: 's16le', 'u32be' and 'u24ne'. Exceptions to this rule that are also valid format specifiers: u8, s8, floatle, floatbe, floatne, mulaw, alaw, mpeg2, ac3 and imaadpcm.

volume[=v[:sc]]

Implements software volume control. Use this filter with caution since it can reduce the signal to noise ratio of the sound. In most cases it is best to set the level for the PCM sound to max, leave this filter out and control the output level to your speakers with the master volume control of the mixer. In case your sound card has a digital PCM mixer instead of an analog one, and you hear distortion, use the MASTER mixer instead. If there is an external amplifier connected to the computer (this is almost always the case), the noise level can be minimized by adjusting the master level and the volume knob on the amplifier until the hissing noise in the background is gone.

This filter has a second feature: It measures the overall maximum sound level and prints out that level when MPlayer exits. This volume estimate can be used for setting the sound level in MEncoder such that the maximum dynamic range is utilized.

NOTE: This filter is not reentrant and can therefore only be enabled once for every audio stream. Sets the desired gain in dB for all channels in the stream from -200dB to +60dB, where -200dB mutes the sound completely and +60dB equals a gain of 1000 (default: 0). Turns soft clipping on (1) or off (0). Soft-clipping can make the sound more smooth if very high volume levels are used. Enable this option if the dynamic range of the loudspeakers is very low.

WARNING: This feature creates distortion and should be considered a last resort. EXAMPLE: Would amplify the sound by 10.1dB and hard-clip if the sound level is too high.

pan=n[:l01:l02:...l10:l11:l12:...ln0:ln1:ln2:...]

Mixes channels arbitrarily. Basically a combination of the volume and the channels filter that can be used to down-mix many channels to only a few, e.g. stereo to mono or vary the "width" of the center speaker in a surround sound system. This filter is hard to use, and will require some tinkering before the desired result is obtained. The number of options for this filter depends on the number of output channels. An example how to downmix a six-channel file to two channels with this filter can be found in the examples section near the end. number of output channels (1-6) How much of input channel i is mixed into output channel j (0-1). So in principle you first have n numbers saying what to do with the first input channel, then n numbers that act on the second input channel etc. If you do not specify any numbers for some input channels, 0 is assumed. EXAMPLE: Would down-mix from stereo to mono. Would give 3 channel output leaving channels 0 and 1 intact, and mix channels 0 and 1 into output channel 2 (which could be sent to a subwoofer for example).

sub[=fc:ch]

Adds a subwoofer channel to the audio stream. The audio data used for creating the subwoofer channel is an average of the sound in channel 0 and channel 1. The resulting sound is then low-pass filtered by a 4th order Butterworth filter with a default cutoff frequency of 60Hz and added to a separate channel in the audio stream.

Warning: Disable this filter when you are playing DVDs with Dolby Digital 5.1 sound, otherwise this filter will disrupt the sound to the subwoofer. cutoff frequency in Hz for the low-pass filter (20Hz to 300Hz) (default: 60Hz) For the best result try setting the cutoff frequency as low as possible. This will improve the stereo or surround sound experience. Determines the channel number in which to insert the sub-channel audio. Channel number can be between 0 and 5 (default: 5). Observe that the number of channels will automatically be increased to <ch> if necessary. EXAMPLE: Would add a sub-woofer channel with a cutoff frequency of 100Hz to output channel 4.

center

Creates a center channel from the front channels. May currently be low quality as it does not implement a high-pass filter for proper extraction yet, but averages and halves the channels instead. Determines the channel number in which to insert the center channel. Channel number can be between 0 and 5 (default: 5). Observe that the number of channels will automatically be increased to <ch> if necessary.

surround[=delay]

Decoder for matrix encoded surround sound like Dolby Surround. Many files with 2 channel audio actually contain matrixed surround sound. Requires a sound card supporting at least 4 channels. delay time in ms for the rear speakers (0 to 1000) (default: 20) This delay should be set as follows: If d1 is the distance from the listening position to the front speakers and d2 is the distance from the listening position to the rear speakers, then the delay should be set to 15ms if d1 <= d2 and to 15 + 5*(d1-d2) if d1 > d2. EXAMPLE: Would add surround sound decoding with 15ms delay for the sound to the rear speakers.

delay[=ch1:ch2:...]

Delays the sound to the loudspeakers such that the sound from the different channels arrives at the listening position simultaneously. It is only useful if you have more than 2 loudspeakers. The delay in ms that should be imposed on each channel (floating point number between 0 and 1000). To calculate the required delay for the different channels do as follows:

1.

Measure the distance to the loudspeakers in meters in relation to your listening position, giving you the distances s1 to s5 (for a 5.1 system). There is no point in compensating for the subwoofer (you will not hear the difference anyway).

2.

Subtract the distances s1 to s5 from the maximum distance, i.e. s[i] = max(s) - s[i]; i = 1...5.

3.

Calculate the required delays in ms as d[i] = 1000*s[i]/342; i = 1...5. EXAMPLE: Would delay front left and right by 10.5ms, the two rear channels and the sub by 0ms and the center channel by 7ms.

export[=mmapped_file[:nsamples]]

Exports the incoming signal to other processes using memory mapping (mmap()). Memory mapped areas contain a header:

int nch                      /*number of channels*/
int size                     /*buffer size*/
unsigned long long counter   /*Used to keep sync, updated every
                               time new data is exported.*/

The rest is payload (non-interleaved) 16 bit data. file to map data to (default: ~/.mplayer/:mplayer-af_export) number of samples per channel (default: 512) EXAMPLE: Would export 1024 samples per channel to '/tmp/mplayer-af_export'.

extrastereo[=mul]

(Linearly) increases the difference between left and right channels which adds some sort of "live" effect to playback. Sets the difference coefficient (default: 2.5). 0.0 means mono sound (average of both channels), with 1.0 sound will be unchanged, with -1.0 left and right channels will be swapped.

volnorm[=method:target]

Maximizes the volume without distorting the sound. Sets the used method. 1: Use a single sample to smooth the variations via the standard weighted mean over past samples (default).

2: Use several samples to smooth the variations via the standard weighted mean over past samples. Sets the target amplitude as a fraction of the maximum for the sample type (default: 0.25).

ladspa=file:label[:controls...]

Load a LADSPA (Linux Audio Developer's Simple Plugin API) plugin. This filter is reentrant, so multiple LADSPA plugins can be used at once. Specifies the LADSPA plugin library file. If LADSPA_PATH is set, it searches for the specified file. If it is not set, you must supply a fully specified pathname. Specifies the filter within the library. Some libraries contain only one filter, but others contain many of them. Entering 'help' here, will list all available filters within the specified library, which eliminates the use of 'listplugins' from the LADSPA SDK. Controls are zero or more floating point values that determine the behavior of the loaded plugin (for example delay, threshold or gain). In verbose mode (add -v to the MPlayer command line), all available controls and their valid ranges are printed. This eliminates the use of 'analyseplugin' from the LADSPA SDK.

comp

Compressor/expander filter usable for microphone input. Prevents artifacts on very loud sound and raises the volume on very low sound. This filter is untested, maybe even unusable.

gate

Noise gate filter similar to the comp audio filter. This filter is untested, maybe even unusable.

Video filters allow you to modify the video stream and its properties. The syntax is:

-vf <filter1[=parameter1:parameter2:...],filter2,...>

-vop <...,filter2[=parameter1:parameter2:...],filter1> (OBSOLETE)

Setup a chain of video filters, to be applied in reverse order. Deprecated in favor of -vf.

Many parameters are optional and set to default values if omitted. To explicitly use a default value set a parameter to '-1'. Parameters w:h means width x height in pixels, x:y means x;y position counted from the upper left corner of the bigger image.

NOTE: To get a full list of available video filters, see -vf help. Video filters are managed in lists. There are a few commands to manage the filter list.

-vf-add <filter1[,filter2,...]>

-vf <filter>=help

Prints the parameter names and parameter value ranges for a particular filter.

-vf <filter=named_parameter1=value1[:named_parameter2=value2:...]>

Sets a named parameter to the given value. Use on and off or yes and no to set flag parameters.

Available filters are:

crop[=w:h:x:y]

Crops the given part of the image and discards the rest. Useful to remove black bands from widescreen movies. Cropped width and height, defaults to original width and height. Position of the cropped picture, defaults to center.

rectangle[=w:h:x:y]

The plugin responds to the input.conf directive 'change_rectangle' that takes two parameters. width and height (default: -1, maximum possible width where boundaries are still visible.) top left corner position (default: -1, uppermost leftmost)

expand[=w:h:x:y:o:a:r]

Expands (not scales) movie resolution to the given value and places the unscaled original at coordinates x, y. Can be used for placing subtitles/:OSD in the resulting black bands. Expanded width,height (default: original width,height). Negative values for w and h are treated as offsets to the original size. EXAMPLE:

expand=0:-50:0:0

Adds a 50 pixel border to the bottom of the picture. position of original image on the expanded image (default: center) OSD/:subtitle rendering 0: disable (default)

1: enable Expands to fit an aspect instead of a resolution (default: 0). EXAMPLE:

-1: original width/:height

-2: Calculate w/:h using the other dimension and the prescaled aspect ratio.

-3: Calculate w/:h using the other dimension and the original aspect ratio.

spal: 768x576 (square pixel PAL)

dsize[=aspect|w:h:aspect-method:r]

Changes the intended display size/:aspect at an arbitrary point in the filter chain. Aspect can be given as a fraction (4/:3) or floating point number (1.33). Alternatively, you may specify the exact display width and height desired. Note that this filter does not do any scaling itself; it just affects what later scalers (software or hardware) will do when auto-scaling to correct aspect. New display width and height. Can also be these special values: 0: original display width and height

-1: original video width:/height (default)

-2: Calculate w/:h using the other dimension and the original display aspect ratio.

-3: Calculate w/:h using the other dimension and the original video aspect ratio. EXAMPLE:

dsize=800:-2

Specifies a display resolution of 800x600 for a 4/3 aspect video, or 800x450 for a 16/9 aspect video. Modifies width and height according to original aspect ratios. -1: Ignore original aspect ratio (default).

0: Keep display aspect ratio by using <w> and <h> as maximum resolution.

1: Keep display aspect ratio by using <w> and <h> as minimum resolution.

2: Keep video aspect ratio by using <w> and <h> as maximum resolution.

3: Keep video aspect ratio by using <w> and <h> as minimum resolution. EXAMPLE:

Specifies a display resolution of at most 800x600, or smaller, in order to keep aspect. Rounds up to make both width and height divisible by <r> (default: 1).

yuy2

Forces software YV12/:I420/:422P to YUY2 conversion. Useful for video cards/:drivers with slow YV12 but fast YUY2 support.

noformat[=fourcc]

Restricts the colorspace for the next filter without doing any conversion. Unlike the format filter, this will allow any colorspace except the one you specify.

NOTE: For a list of available formats see noformat=fmt=help. format name like rgb15, bgr24, yv12, etc (default: yv12)

pp[=filter1[:option1[:option2...]]/:[-]filter2...] (also see -pphelp)

Enables the specified chain of postprocessing subfilters. Subfilters must be separated by '/' and can be disabled by prepending a '-'. Each subfilter and some options have a short and a long name that can be used interchangeably, i.e. dr/dering are the same. All subfilters share common options to determine their scope: Automatically switch the subfilter off if the CPU is too slow. Do chrominance filtering, too (default). Do luminance filtering only (no chrominance). Do chrominance filtering only (no luminance).

NOTE: -pphelp shows a list of available subfilters. Available subfilters are horizontal deblocking filter <difference>: Difference factor where higher values mean more deblocking (default: 32).

<flatness>: Flatness threshold where lower values mean more deblocking (default: 39). vertical deblocking filter <difference>: Difference factor where higher values mean more deblocking (default: 32).

<flatness>: Flatness threshold where lower values mean more deblocking (default: 39). accurate vertical deblocking filter <difference>: Difference factor where higher values mean more deblocking (default: 32).

<flatness>: Flatness threshold where lower values mean more deblocking (default: 39). The horizontal and vertical deblocking filters share the difference and flatness values so you cannot set different horizontal and vertical thresholds. experimental horizontal deblocking filter experimental vertical deblocking filter deringing filter temporal noise reducer <threshold1>: larger -> stronger filtering

<threshold2>: larger -> stronger filtering

<threshold3>: larger -> stronger filtering automatic brightness / contrast correction f/fullyrange: Stretch luminance to (0-255).

spp[=quality[:qp[:mode]]]

Simple postprocessing filter that compresses and decompresses the image at several (or - in the case of quality level 6 - all) shifts and averages the results. 0-6 (default: 3) Force quantization parameter (default: 0, use QP from video). 0: hard thresholding (default)

1: soft thresholding (better deringing, but blurrier)

4: like 0, but also use B-frames' QP (may cause flicker)

5: like 1, but also use B-frames' QP (may cause flicker)

uspp[=quality[:qp]]

Ultra simple & slow postprocessing filter that compresses and decompresses the image at several (or - in the case of quality level 8 - all) shifts and averages the results. The way this differs from the behavior of spp is that uspp actually encodes & decodes each case with libavcodec MPEG-4, whereas spp uses a simplified intra only 8x8 DCT similar to MJPEG. 0-8 (default: 3) Force quantization parameter (default: 0, use QP from video).

fspp[=quality[:qp[:strength[:bframes]]]]

faster version of the simple postprocessing filter 4-5 (equivalent to spp; default: 4) Force quantization parameter (default: 0, use QP from video). Filter strength, lower values mean more details but also more artifacts, while higher values make the image smoother but also blurrier (default: 0 - PSNR optimal). 0: do not use QP from B-frames (default)

1: use QP from B-frames too (may cause flicker)

pp7[=qp[:mode]]

Variant of the spp filter, similar to spp=6 with 7 point DCT where only the center sample is used after IDCT. Force quantization parameter (default: 0, use QP from video). 0: hard thresholding

1: soft thresholding (better deringing, but blurrier)

2: medium thresholding (default, good results)

qp=equation

quantization parameter (QP) change filter some equation like "2+2*sin(PI*qp)"

test

Generate various test patterns.

rgbtest

Generate an RGB test pattern useful for detecting RGB vs BGR issues. You should see a red, green and blue stripe from top to bottom.

lavc[=quality:fps]

Fast software YV12 to MPEG-1 conversion with libavcodec for use with DVB/:DXR3. Faster and of better quality than -vf fame. 1-31: fixed qscale

32-: fixed bitrate in kbits force output fps (float value) (default: 0, autodetect based on height)

fame

Fast software YV12 to MPEG-1 conversion with libfame for use with DVB/:DXR3.

dvbscale[=aspect]

Set up optimal scaling for DVB cards, scaling the x axis in hardware and calculating the y axis scaling in software to keep aspect. Only useful together with expand and scale. Control aspect ratio, calculate as DVB_HEIGHT*ASPECTRATIO (default: 576*4/:3=768), set it to 576*(16/:9)=1024 for a 16:9 TV. EXAMPLE: FIXME: Explain what this does.

noise[=luma[u][t|a][h][p]:chroma[u][t|a][h][p]]

Adds noise. luma noise chroma noise uniform noise (gaussian otherwise) temporal noise (noise pattern changes between frames) averaged temporal noise (smoother, but a lot slower) high quality (slightly better looking, slightly slower) mix random noise with a (semi)regular pattern

denoise3d[=luma:chroma:time]

This filter aims to reduce image noise producing smooth images and making still images really still (This should enhance compressibility.). spatial luma strength (default: 4) spatial chroma strength (default: 3) temporal strength (default: 6)

hqdn3d[=luma:chroma:time]

High precision/:quality version of the denoise3d filter. Parameters and usage are the same.

eq[=brightness:contrast] (OBSOLETE)

Software equalizer with interactive controls just like the hardware equalizer, for cards/:drivers that do not support brightness and contrast controls in hardware. Might also be useful with MEncoder, either for fixing poorly captured movies, or for slightly reducing contrast to mask artifacts and get by with lower bitrates. initial brightness initial contrast

eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]

Alternative software equalizer that uses lookup tables (very slow), allowing gamma correction in addition to simple brightness and contrast adjustment. Note that it uses the same MMX optimized code as -vf eq if all gamma values are 1.0. The parameters are given as floating point values. initial gamma value (default: 1.0) initial contrast, where negative values result in a negative image (default: 1.0) initial brightness (default: 0.0) initial saturation (default: 1.0) gamma value for the red component (default: 1.0) gamma value for the green component (default: 1.0) gamma value for the blue component (default: 1.0) The weight parameter can be used to reduce the effect of a high gamma value on bright image areas, e.g. keep them from getting overamplified and just plain white. A value of 0.0 turns the gamma correction all the way down while 1.0 leaves it at its full strength (default: 1.0).

hue[=hue:saturation]

Software equalizer with interactive controls just like the hardware equalizer, for cards/:drivers that do not support hue and saturation controls in hardware. initial hue (default: 0.0) initial saturation, where negative values result in a negative chroma (default: 1.0)

halfpack[=f]

Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but keeping all chroma samples. Useful for output to low-resolution display devices when hardware downscaling is poor quality or is not available. Can also be used as a primitive luma-only deinterlacer with very low CPU usage. By default, halfpack averages pairs of lines when downsampling. Any value different from 0 or 1 gives the default (averaging) behavior. 0: Only use even lines when downsampling.

1: Only use odd lines when downsampling.

ilpack[=mode]

When interlaced video is stored in YUV 4:2:0 formats, chroma interlacing does not line up properly due to vertical downsampling of the chroma channels. This filter packs the planar 4:2:0 data into YUY2 (4:2:2) format with the chroma lines in their proper locations, so that in any given scanline, the luma and chroma data both come from the same field. Select the sampling mode. 0: nearest-neighbor sampling, fast but incorrect

1: linear interpolation (default)

harddup

Only useful with MEncoder. If harddup is used when encoding, it will force duplicate frames to be encoded in the output. This uses slightly more space, but is necessary for output to MPEG files or if you plan to demux and remux the video stream after encoding. Should be placed at or near the end of the filter chain unless you have a good reason to do otherwise.

softskip

Only useful with MEncoder. Softskip moves the frame skipping (dropping) step of encoding from before the filter chain to some point during the filter chain. This allows filters which need to see all frames (inverse telecine, temporal denoising, etc.) to function properly. Should be placed after the filters which need to see all frames and before any subsequent filters that are CPU-intensive.

decimate[=max:hi:lo:frac]

Drops frames that do not differ greatly from the previous frame in order to reduce framerate. The main use of this filter is for very-low-bitrate encoding (e.g. streaming over dialup modem), but it could in theory be used for fixing movies that were inverse-telecined incorrectly. Sets the maximum number of consecutive frames which can be dropped (if positive), or the minimum interval between dropped frames (if negative). A frame is a candidate for dropping if no 8x8 region differs by more than a threshold of <hi>, and if not more than <frac> portion (1 meaning the whole image) differs by more than a threshold of <lo>. Values of <hi> and <lo> are for 8x8 pixel blocks and represent actual pixel value differences, so a threshold of 64 corresponds to 1 unit of difference for each pixel, or the same spread out differently over the block.

dint[=sense:level]

The drop-deinterlace (dint) filter detects and drops the first from a set of interlaced video frames. relative difference between neighboring pixels (default: 0.1) What part of the image has to be detected as interlaced to drop the frame (default: 0.15).

lavcdeint (OBSOLETE)

FFmpeg deinterlacing filter, same as -vf pp=fd

kerndeint[=thresh[:map[:order[:sharp[:twoway]]]]]

Donald Graft's adaptive kernel deinterlacer. Deinterlaces parts of a video if a configurable threshold is exceeded. threshold (default: 10) 0: Ignore pixels exceeding the threshold (default).

1: Paint pixels exceeding the threshold white. 0: Leave fields alone (default).

1: Swap fields. 0: Disable additional sharpening (default).

1: Enable additional sharpening. 0: Disable twoway sharpening (default).

1: Enable twoway sharpening.

unsharp[=l|cWxH:amount[:l|cWxH:amount]]

unsharp mask / gaussian blur Apply effect on luma component. Apply effect on chroma components. width and height of the matrix, odd sized in both directions (min = 3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7) Relative amount of sharpness/:blur to add to the image (a sane range should be -1.5-1.5). <0: blur

>0: sharpen

swapuv

Swap U & V plane.

il[=d|i][s][:[d|i][s]]

(De)interleaves lines. The goal of this filter is to add the ability to process interlaced images pre-field without deinterlacing them. You can filter your interlaced DVD and play it on a TV without breaking the interlacing. While deinterlacing (with the postprocessing filter) removes interlacing permanently (by smoothing, averaging, etc) deinterleaving splits the frame into 2 fields (so called half pictures), so you can process (filter) them independently and then re-interleave them. deinterleave (placing one above the other) interleave swap fields (exchange even & odd lines)

fil[=i|d]

(De)interleaves lines. This filter is very similar to the il filter but much faster, the main disadvantage is that it does not always work. Especially if combined with other filters it may produce randomly messed up images, so be happy if it works but do not complain if it does not for your combination of filters. Deinterleave fields, placing them side by side. Interleave fields again (reversing the effect of fil=d).

field[=n]

Extracts a single field from an interlaced image using stride arithmetic to avoid wasting CPU time. The optional argument n specifies whether to extract the even or the odd field (depending on whether n is even or odd).

detc[=var1=value1:var2=value2:...]

Attempts to reverse the 'telecine' process to recover a clean, non-interlaced stream at film framerate. This was the first and most primitive inverse telecine filter to be added to MPlayer/:MEncoder. It works by latching onto the telecine 3:2 pattern and following it as long as possible. This makes it suitable for perfectly-telecined material, even in the presence of a fair degree of noise, but it will fail in the presence of complex post-telecine edits. Development on this filter is no longer taking place, as ivtc, pullup, and filmdint are better for most applications. The following arguments (see syntax above) may be used to control detc's behavior: Set the frame dropping mode. 0: Do not drop frames to maintain fixed output framerate (default).

1: Always drop a frame when there have been no drops or telecine merges in the past 5 frames.

2: Always maintain exact 5:4 input to output frame ratio.

NOTE: Use mode 1 or 2 with MEncoder. Analysis mode. 0: Fixed pattern with initial frame number specified by <fr>.

1: aggressive search for telecine pattern (default) Set initial frame number in sequence. 0-2 are the three clean progressive frames; 3 and 4 are the two interlaced frames. The default, -1, means 'not in telecine sequence'. The number specified here is the type for the imaginary previous frame before the movie starts. Threshold values to be used in certain modes.

ivtc[=1]

Experimental 'stateless' inverse telecine filter. Rather than trying to lock on to a pattern like the detc filter does, ivtc makes its decisions independently for each frame. This will give much better results for material that has undergone heavy editing after telecine was applied, but as a result it is not as forgiving of noisy input, for example TV capture. The optional parameter (ivtc=1) corresponds to the dr=1 option for the detc filter, and should be used with MEncoder but not with MPlayer. As with detc, you must specify the correct output framerate (-ofps 24000/1001) when using MEncoder. Further development on ivtc has stopped, as the pullup and filmdint filters appear to be much more accurate.

pullup[=jl:jr:jt:jb:sb:mp]

Third-generation pulldown reversal (inverse telecine) filter, capable of handling mixed hard-telecine, 24000/1001 fps progressive, and 30000/1001 fps progressive content. The pullup filter is designed to be much more robust than detc or ivtc, by taking advantage of future context in making its decisions. Like ivtc, pullup is stateless in the sense that it does not lock onto a pattern to follow, but it instead looks forward to the following fields in order to identify matches and rebuild progressive frames. It is still under development, but believed to be quite accurate. The jl, jr, jt, and jb options set the amount of "junk" to ignore at the left, right, top, and bottom of the image, respectively. Left/:right are in units of 8 pixels, while top/:bottom are in units of 2 lines. The default is 8 pixels on each side. Setting the sb (strict breaks) option to 1 will reduce the chances of pullup generating an occasional mismatched frame, but it may also cause an excessive number of frames to be dropped during high motion sequences. Conversely, setting it to -1 will make pullup match fields more easily. This may help processing of video where there is slight blurring between the fields, but may also cause there to be interlaced frames in the output. The mp (metric plane) option may be set to 1 or 2 to use a chroma plane instead of the luma plane for doing pullup's computations. This may improve accuracy on very clean source material, but more likely will decrease accuracy, especially if there is chroma noise (rainbow effect) or any grayscale video. The main purpose of setting mp to a chroma plane is to reduce CPU load and make pullup usable in realtime on slow machines.

NOTE: Always follow pullup with the softskip filter when encoding to ensure that pullup is able to see each frame. Failure to do so will lead to incorrect output and will usually crash, due to design limitations in the codec/:filter layer.

filmdint[=options]

Inverse telecine filter, similar to the pullup filter above. It is designed to handle any pulldown pattern, including mixed soft and hard telecine and limited support for movies that are slowed down or sped up from their original framerate for TV. Only the luma plane is used to find the frame breaks. If a field has no match, it is deinterlaced with simple linear approximation. If the source is MPEG-2, this must be the first filter to allow access to the field-flags set by the MPEG-2 decoder. Depending on the source MPEG, you may be fine ignoring this advice, as long as you do not see lots of "Bottom-first field" warnings. With no options it does normal inverse telecine, and should be used together with mencoder -fps 30000/1001 -ofps 24000/1001. When this filter is used with mplayer, it will result in an uneven framerate during playback, but it is still generally better than using pp=lb or no deinterlacing at all. Multiple options can be specified separated by /. Just like the crop filter, but faster, and works on mixed hard and soft telecined content as well as when y is not a multiple of 4. If x or y would require cropping fractional pixels from the chroma planes, the crop area is extended. This usually means that x and y must be even. For each ifps input frames the filter will output ofps frames. The ratio of ifps/:ofps should match the -fps/-ofps ratio. This could be used to filter movies that are broadcast on TV at a frame rate different from their original framerate. If n is nonzero, the chroma plane is copied unchanged. This is useful for YV12 sampled TV, which discards one of the chroma fields. On x86, if n=1, use MMX2 optimized functions, if n=2, use 3DNow! optimized functions, otherwise, use plain C. If this option is not specified, MMX2 and 3DNow! are auto-detected, use this option to override auto-detection. The larger n will speed up the filter at the expense of accuracy. The default value is n=3. If n is odd, a frame immediately following a frame marked with the REPEAT_FIRST_FIELD MPEG flag is assumed to be progressive, thus filter will not spend any time on soft-telecined MPEG-2 content. This is the only effect of this flag if MMX2 or 3DNow! is available. Without MMX2 and 3DNow, if n=0 or 1, the same calculations will be used as with n=2 or 3. If n=2 or 3, the number of luma levels used to find the frame breaks is reduced from 256 to 128, which results in a faster filter without losing much accuracy. If n=4 or 5, a faster, but much less accurate metric will be used to find the frame breaks, which is more likely to misdetect high vertical detail as interlaced content. If n is nonzero, print the detailed metrics for each frame. Useful for debugging. Deinterlace threshold. Used during de-interlacing of unmatched frames. Larger value means less deinterlacing, use n=256 to completely turn off deinterlacing. Default is n=8. Threshold for comparing a top and bottom fields. Defaults to 128. Threshold to detect temporal change of a field. Default is 128. Sum of Absolute Difference threshold, default is 64.

softpulldown

This filter works only correct with MEncoder and acts on the MPEG-2 flags used for soft 3:2 pulldown (soft telecine). If you want to use the ivtc or detc filter on movies that are partly soft telecined, inserting this filter before them should make them more reliable.

divtc[=options]

Inverse telecine for deinterlaced video. If 3:2-pulldown telecined video has lost one of the fields or is deinterlaced using a method that keeps one field and interpolates the other, the result is a juddering video that has every fourth frame duplicated. This filter is intended to find and drop those duplicates and restore the original film framerate. When using this filter, you must specify -ofps that is 4/:5 of the fps of the input file and place the softskip later in the filter chain to make sure that divtc sees all the frames. Two different modes are available: One pass mode is the default and is straightforward to use, but has the disadvantage that any changes in the telecine phase (lost frames or bad edits) cause momentary judder until the filter can resync again. Two pass mode avoids this by analyzing the whole video beforehand so it will have forward knowledge about the phase changes and can resync at the exact spot. These passes do not correspond to pass one and two of the encoding process. You must run an extra pass using divtc pass one before the actual encoding throwing the resulting video away. Use -nosound -ovc raw -o /dev/null to avoid wasting CPU power for this pass. You may add something like crop=2:2:0:0 after divtc to speed things up even more. Then use divtc pass two for the actual encoding. If you use multiple encoder passes, use divtc pass two for all of them. The options are: Use two pass mode. Set the two pass log filename (default: "framediff.log"). Set the minimum strength the telecine pattern must have for the filter to believe in it (default: 0.5). This is used to avoid recognizing false pattern from the parts of the video that are very dark or very still. Set the number of past frames to look at when searching for pattern (default: 30). Longer window improves the reliability of the pattern search, but shorter window improves the reaction time to the changes in the telecine phase. This only affects the one pass mode. The two pass mode currently uses fixed window that extends to both future and past. Sets the initial telecine phase for one pass mode (default: 0). The two pass mode can see the future, so it is able to use the correct phase from the beginning, but one pass mode can only guess. It catches the correct phase when it finds it, but this option can be used to fix the possible juddering at the beginning. The first pass of the two pass mode also uses this, so if you save the output from the first pass, you get constant phase result. Set the deghosting threshold (0-255 for one pass mode, -255-255 for two pass mode, default 0). If nonzero, deghosting mode is used. This is for video that has been deinterlaced by blending the fields together instead of dropping one of the fields. Deghosting amplifies any compression artifacts in the blended frames, so the parameter value is used as a threshold to exclude those pixels from deghosting that differ from the previous frame less than specified value. If two pass mode is used, then negative value can be used to make the filter analyze the whole video in the beginning of pass-2 to determine whether it needs deghosting or not and then select either zero or the absolute value of the parameter. Specify this option for pass-2, it makes no difference on pass-1.

phase[=t|b|p|a|u|T|B|A|U][:v]

Delay interlaced video by one field time so that the field order changes. The intended use is to fix PAL movies that have been captured with the opposite field order to the film-to-video transfer. The options are: Capture field order top-first, transfer bottom-first. Filter will delay the bottom field. Capture bottom-first, transfer top-first. Filter will delay the top field. Capture and transfer with the same field order. This mode only exists for the documentation of the other options to refer to, but if you actually select it, the filter will faithfully do nothing ;-) Capture field order determined automatically by field flags, transfer opposite. Filter selects among t and b modes on a frame by frame basis using field flags. If no field information is available, then this works just like u. Capture unknown or varying, transfer opposite. Filter selects among t and b on a frame by frame basis by analyzing the images and selecting the alternative that produces best match between the fields. Capture top-first, transfer unknown or varying. Filter selects among t and p using image analysis. Capture bottom-first, transfer unknown or varying. Filter selects among b and p using image analysis. Capture determined by field flags, transfer unknown or varying. Filter selects among t, b and p using field flags and image analysis. If no field information is available, then this works just like U. This is the default mode. Both capture and transfer unknown or varying. Filter selects among t, b and p using image analysis only. Verbose operation. Prints the selected mode for each frame and the average squared difference between fields for t, b, and p alternatives.

telecine[=start]

Apply 3:2 'telecine' process to increase framerate by 20%. This most likely will not work correctly with MPlayer, but it can be used with 'mencoder -fps 30000/1001 -ofps 30000/1001 -vf telecine'. Both fps options are essential! (A/:V sync will break if they are wrong.) The optional start parameter tells the filter where in the telecine pattern to start (0-3).

tinterlace[=mode]

Temporal field interlacing - merge pairs of frames into an interlaced frame, halving the framerate. Even frames are moved into the upper field, odd frames to the lower field. This can be used to fully reverse the effect of the tfields filter (in mode 0). Available modes are: Move odd frames into the upper field, even into the lower field, generating a full-height frame at half framerate. Only output odd frames, even frames are dropped; height unchanged. Only output even frames, odd frames are dropped; height unchanged. Expand each frame to full height, but pad alternate lines with black; framerate unchanged.

tfields[=mode[:field_dominance]]

Temporal field separation - split fields into frames, doubling the output framerate. Like the telecine filter, tfields will only work properly with MEncoder, and only if both -fps and -ofps are set to the desired (double) framerate! Available modes are: Leave fields unchanged. (This will jump/:flicker.) Interpolate missing lines. (The algorithm used might not be so good.) Translate fields by 1/4 pixel with linear interpolation (no jump). Translate fields by 1/4 pixel with 4tap filter (higher quality). (default) Available field dominances are: auto (default) Only works if the decoder exports the appropriate information and no other filters which discard that information come before tfields in the filter chain, otherwise it falls back to 0 (top field first). top-first bottom-first

boxblur=radius:power[:radius:power]

box blur blur filter strength number of filter applications

sab=radius:pf:colorDiff[:radius:pf:colorDiff]

shape adaptive blur blur filter strength (~0.1-4.0) (slower if larger) prefilter strength (~0.1-2.0) maximum difference between pixels to still be considered (~0.1-100.0)

smartblur=radius:strength:threshold[:radius:strength:threshold]

smart blur blur filter strength (~0.1-5.0) (slower if larger) blur (0.0-1.0) or sharpen (-1.0-0.0) filter all (0), filter flat areas (0-30) or filter edges (-30-0)

perspective=x0:y0:x1:y1:x2:y2:x3:y3:t

Correct the perspective of movies not filmed perpendicular to the screen. coordinates of the top left, top right, bottom left, bottom right corners linear (0) or cubic resampling (1)

2xsai

Scale and smooth the image with the 2x scale and interpolate algorithm.

1bpp

1bpp bitmap to YUV/:BGR 8/:15/:16/:32 conversion

down3dright[=lines]

Reposition and resize stereoscopic images. Extracts both stereo fields and places them side by side, resizing them to maintain the original movie aspect. number of lines to select from the middle of the image (default: 12)

bmovl=hidden:opaque:fifo

The bitmap overlay filter reads bitmaps from a FIFO and displays them on top of the movie, allowing some transformations on the image. Also see TOOLS/bmovl-test.c for a small bmovl test program. Set the default value of the 'hidden' flag (0=visible, 1=hidden). Set the default value of the 'opaque' flag (0=transparent, 1=opaque). path/:filename for the FIFO (named pipe connecting 'mplayer -vf bmovl' to the controlling application) FIFO commands are: followed by width*height*4 Bytes of raw RGBA32 data. followed by width*height*4 Bytes of raw ABGR32 data. followed by width*height*3 Bytes of raw RGB24 data. followed by width*height*3 Bytes of raw BGR24 data. Change alpha transparency of the specified area. Clear area. Disable all alpha transparency. Send "ALPHA 0 0 0 0 0" to enable it again. Hide bitmap. Show bitmap. Arguments are: image/area size Start blitting at position x/y. Set alpha difference. If you set this to -255 you can then send a sequence of ALPHA-commands to set the area to -225, -200, -175 etc for a nice fade-in-effect! ;) 0: same as original

255: Make everything opaque.

-255: Make everything transparent. Clear the framebuffer before blitting. 0: The image will just be blitted on top of the old one, so you do not need to send 1.8MB of RGBA32 data every time a small part of the screen is updated.

1: clear

framestep=I|[i]step

Renders only every nth frame or every intra frame (keyframe). If you call the filter with I (uppercase) as the parameter, then only keyframes are rendered. For DVDs it generally means one in every 15/:12 frames (IBBPBBPBBPBBPBB), for AVI it means every scene change or every keyint value (see -lavcopts keyint= value if you use MEncoder to encode the video). When a keyframe is found, an 'I!' string followed by a newline character is printed, leaving the current line of MPlayer/:MEncoder output on the screen, because it contains the time (in seconds) and frame number of the keyframe (You can use this information to split the AVI.). If you call the filter with a numeric parameter 'step' then only one in every 'step' frames is rendered. If you put an 'i' (lowercase) before the number then an 'I!' is printed (like the I parameter). If you give only the i then nothing is done to the frames, only I! is printed.

tile=xtiles:ytiles:output:start:delta

Tile a series of images into a single, bigger image. If you omit a parameter or use a value less than 0, then the default value is used. You can also stop when you are satisfied (... -vf tile=10:5 ...). It is probably a good idea to put the scale filter before the tile :-) The parameters are: number of tiles on the x axis (default: 5) number of tiles on the y axis (default: 5) Render the tile when 'output' number of frames are reached, where 'output' should be a number less than xtile * ytile. Missing tiles are left blank. You could, for example, write an 8 * 7 tile every 50 frames to have one image every 2 seconds @ 25 fps. outer border thickness in pixels (default: 2) inner border thickness in pixels (default: 4)

delogo[=x:y:w:h:t]

Suppresses a TV station logo by a simple interpolation of the surrounding pixels. Just set a rectangle covering the logo and watch it disappear (and sometimes something even uglier appear - your mileage may vary). top left corner of the logo width and height of the cleared rectangle Thickness of the fuzzy edge of the rectangle (added to w and h). When set to -1, a green rectangle is drawn on the screen to simplify finding the right x,y,w,h parameters.

remove-logo=/path/to/logo_bitmap_file_name.pgm

Suppresses a TV station logo, using a PGM or PPM image file to determine which pixels comprise the logo. The width and height of the image file must match those of the video stream being processed. Uses the filter image and a circular blur algorithm to remove the logo. [path] + filename of the filter image.

zrmjpeg[=options]

Software YV12 to MJPEG encoder for use with the zr2 video output device. These options set the maximum width and height the zr card can handle (the MPlayer filter layer currently cannot query those). Use these options to set maxwidth and maxheight automatically to the values known for card/:mode combo. For example, valid options are: dc10-PAL and buz-NTSC (default: dc10+PAL) Select color or black and white encoding. Black and white encoding is faster. Color is the default. Horizontal decimation 1, 2 or 4. Vertical decimation 1, 2 or 4. Set JPEG compression quality [BEST] 1 - 20 [VERY BAD]. By default, decimation is only performed if the Zoran hardware can upscale the resulting MJPEG images to the original size. The option fd instructs the filter to always perform the requested decimation (ugly).

screenshot

Allows acquiring screenshots of the movie using the screenshot command (bound to the 's' key by default). Files named 'shotNNNN.png' will be saved in the working directory, using the first available number - no files will be overwritten. The filter has no overhead when not used and accepts an arbitrary colorspace, so it is safe to add it to the configuration file.

-audio-delay <0.0-...>

Sets the audio delay field in the header. Default is 0.0, negative values do not work. This does not delay the audio while encoding, but the player will see the default audio delay, sparing you the use of the -delay option.

-audio-density <1-50>

Number of audio chunks per second (default is 2 for 0.5s long audio chunks).

NOTE: CBR only, VBR ignores this as it puts each packet in a new chunk.

-audio-preload <0.0-2.0>

Sets up the audio buffering time interval (default: 0.5s).

-endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (also see -ss and -sb)

Stop encoding at the given time or byte position.

NOTE: Byte position will not be accurate, as it can only stop at a frame boundary. EXAMPLE: Encode only 56 seconds. Encode only 1 hour 10 minutes. Encode only 100 MB.

-fafmttag <format>

Can be used to override the audio format tag of the output file. EXAMPLE: Will have the output file contain 0x55 (mp3) as audio format tag.

-ffourcc <fourcc>

Can be used to override the video fourcc of the output file. EXAMPLE: Will have the output file contain 'div3' as video fourcc.

-force-avi-aspect <0.2-3.0>

Override the aspect stored in the AVI OpenDML vprp header. This can be used to change the aspect ratio with '-ovc copy'.

-frameno-file <filename> (DEPRECATED)

Specify the name of the audio file with framenumber mappings created in the first (audio only) pass of a special three pass encoding mode.

NOTE: Using this mode will most likely give you A-V desync. Do not use it. It is kept for backwards compatibility only and will possibly be removed in a future version.

-hr-edl-seek (EDL only)

Use a more precise, but much slower method for skipping areas. Areas marked for skipping are not seeked over, instead all frames are decoded, but only the necessary frames are encoded. This allows starting at non-keyframe boundaries.

NOTE: Not guaranteed to work right with '-ovc copy'.

-info <option1:option2:...> (AVI only)

Specify the info header of the resulting AVI file. Available options are: Show this description. title of the work artist or author of the work original work category contents of the work copyright information original format of the digitized material general comments about the work

-noautoexpand

Do not automatically insert the expand filter into the MEncoder filter chain. Useful to control at which point of the filter chain subtitles are rendered when hardcoding subtitles onto a movie.

-noencodedups

Do not attempt to encode duplicate frames in duplicate; always output zero-byte frames to indicate duplicates. Zero-byte frames will be written anyway unless a filter or encoder capable of doing duplicate encoding is loaded. Currently the only such filter is harddup.

-noodml (-of avi only)

Do not write OpenDML index for AVI files >1GB.

-noskip

Do not skip frames.

-o <filename>

Outputs to the given filename.

If you want a default output filename, you can put this option in the MEncoder config file.

-oac <codec name>

Encode with the given audio codec (no default set).

NOTE: Use -oac help to get a list of available audio codecs. EXAMPLE: no encoding, just streamcopy Encode to uncompressed PCM. Encode to MP3 (using LAME). Encode with a libavcodec codec.

-of <format> (BETA CODE!)

Encode to the specified container format (default: AVI).

NOTE: Use -of help to get a list of available container formats. EXAMPLE: Encode to AVI. Encode to MPEG (also see -mpegopts). Encode with libavformat muxers (also see -lavfopts). raw video stream (no muxing - one video stream only) raw audio stream (no muxing - one audio stream only)

-ofps <fps>

Specify a frames per second (fps) value for the output file, which can be different from that of the source material. Must be set for variable fps (ASF, some MOV) and progressive (30000/1001 fps telecined MPEG) files.

-ovc <codec name>

Encode with the given video codec (no default set).

NOTE: Use -ovc help to get a list of available video codecs. EXAMPLE: no encoding, just streamcopy Encode to DivX4/:DivX5. Encode to an arbitrary uncompressed format (use '-vf format' to select). Encode with a libavcodec codec.

-passlogfile <filename>

Dump first pass information to <filename> instead of the default divx2pass.log in two pass encoding mode.

-skiplimit <value>

Specify the maximum number of frames that may be skipped after encoding one frame (-noskiplimit for unlimited).

-vobsubout <basename>

Specify the basename for the output .idx and .sub files. This turns off subtitle rendering in the encoded movie and diverts it to VOBsub subtitle files.

-vobsuboutid <langid>

Specify the language two letter code for the subtitles. This overrides what is read from the DVD or the .ifo file.

-vobsuboutindex <index>

Specify the index of the subtitles in the output files (default: 0).

You can specify codec specific encoding parameters using the following syntax:

-<codec>opts <option1[=value],option2,...>

Where <codec> may be: lavc, xvidenc, divx4, lame, toolame, twolame, nuv, vfw, faac, x264enc, mpeg, lavf.

divx4 (-divx4opts)

lame (-lameopts)

toolame and twolame (-toolameopts and -twolameopts respectively)

faac (-faacopts)

lavc (-lavcopts)

nuv (-nuvopts)

xvidenc (-xvidencopts)

x264enc (-x264encopts)

MPEG muxer (-mpegopts)

FFmpeg libavformat muxers (-lavfopts) (also see -of lavf)
