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.
Thanks for any replies.

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.
