In Linux, is it possible to use the command line to command one of those video capture/tuner cards to begin recording to a file? I was discussing the virtues of Linux with a friend and said that if these cards can at least be commanded to start and stop recording via the command line, all the power of at and cron are available. It would also be easier to remotely control a system if the CLI works kind of like the sound commands of aplay and arecord commands do.

Hi martin,I do this often with my pixelview. I have some scripts with the commands below, maybe they can help you. Its easy, actually.
(this is all one line command)mencoder -oac lavc -lavcopts acodec=mp3 -ovc lavc -lavcopts vbitrate=1800 -ffourcc divx -tv driver=v4l2:norm=pal-m:input=1:adevice=/dev/dsp:width=640:height=480 -vf pp=lb -o /backup/filme-`date +%H:%M-%d-%m-%Y`.avi tv://
the ffourcc thing is supposed to improve win compatibility. streamer can also be used, as already said. streamer -t 00:05:00 -s 640x480 -r 24 -o ~file.avi -f mjpeg -F stereo Search google for other examples with mencoder. Its a great software.
