zapping - a TV viewer for the Gnome environment

Zapping is a program to watch TV on a computer, within the Gnome environment. You can take screenshots and record video and audio. Zapping has a Teletext viewer built in and supports Closed Caption and Teletext subtitles. It is extensible through plugins. For more information open the Gnome help and choose Applications -> Sound and Video -> Zapping.

-b, --bpp NUMBER

Color depth of the X display. In TrueColor mode (24 or 32 bits per pixel) you might get a very distorted image that spreads all around the desktop. This usually means Zapping could not correctly determine the color depth, which can be given here.

-c, --command COMMAND

Execute the given command and exit. This was intended to create a sort of batch mode. Currently only one command is implemented. In the future this option will probably be replaced by a lightweight tool to control Zapping remotely. The set_channel command allows to change the channel by giving the channel name or RF channel number, for example:

zapping -c "set_channel BBC"

--console-errors

Redirect the error messages to the console, useful for bug reports.

--cpu-features

Override the CPU detection for tests. Possible features are: mmx, 3dnow, sse, sse2, altivec.

-d, --debug

Print debug messages on standard output. You should include this information when submitting a bug report, as it can help to trace the problem.

--device FILENAME

Kernel video device to use, usually /dev/video.

--dword-align

Forces doubleword alignment of the video in overlay mode. Can help when the image is distorted at certain sizes but looks fine at others.

-n, --tunerless-norm STRING

This option has no function but is recognized for compatibility with earlier versions of Zapping. It determined the video standard to be used when your TV card has no tuner, one of NTSC, PAL or SECAM.

--no-overlay, --remote

Do not overlay video. The --remote option refers to the X display. Overlay is only possible if the graphics card connects to the same bus as the TV card.

--no-plugins

Do not use any plugins, usually for testing purposes.

--no-vbi

Do not capture and decode VBI data, i.e. Teletext, Subtitles, Closed Caption and station names.

--no-xv-video

Do not use the XVideo extension for video overlay.

--no-xv-image

Do not use the XVideo extension for hardware image scaling.

-v, --no-xv

Do not use the XVideo extension for video overlay or hardware image scaling.

--xv-image-port NUMBER

Number of the XVideo port to use for hardware image scaling.

--xv-port NUMBER, --xv-video-port NUMBER

Number of the XVideo port (similar to a device) to use for video overlay.

-y, --yuv-format STRING

This option has no function but is recognized for compatibility with earlier versions of Zapping. It determined the pixel format in capture mode when XVideo hardware image scaling was available, either YUYV or YVU420.

-z, --no-zsfb

This option has no function but is recognized for compatibility with earlier versions of Zapping. It used to prevent execution of zapping_setup_fb(1) on startup.

zapping_setup_fb(1)
