Capturing desktop

Anikom15 · 2010-01-31 02:22:20

I need to capture the desktop into a video stream, preferably recording audio input from the mic at the same time. I know there are programs to do this, but surely there's an awesome command line way with ffmpeg or something.

man ffmpeg

Search for x11grab. FFmpeg supports both oss and alsa by default, but I'm not sure if the man page covers alsa.

Is it possible to get it straight off the graphics card, rather than X11?

Interesting question. Do you want to record from outside of X, like in the console, or directly from the video card itself?

Directly from the card.

You can capture from /dev/video{0,1,2...etc} with some sort of format like x11grab or video4linux (1 or 2), but whether or not you can grab directly from the device is beyond me.

Maybe I can trick the card into thinking it's running 2 cloned displays, when the second display is a video container. Hmm . . . maybe some gnarly C hacker could do this one.
