man xwd2raw (Commandes) - Use an X Window as a source for Raw DV images.

NAME

xwd2raw - Use an X Window as a source for Raw DV images.

xwd2raw [ options ]

xwd2raw captures an X Windows as a Raw DV stream

-n: NTSC output required (default: PAL).
-w window: Specify window to capture (default is whole screen).
-i id: X Window id to capture.
-s: Interactively select the X Window to capture.
-m: Use Image Magick tools to convert the xwd image (this may be a better option from a performance point of view and seems to work better than the xwdtopnm utility which is used by default).

Interactively select a window, and send to your cam:

xwd2raw -s |

dvconnect -s --

Interactively select a window, and play the stream:

xwd2raw -s |

playdv --
