A window manager is available
video /dev/video0

flags: capture
To record video, I used this scriptshell function with ffmpeg:
function record_cam () {
[ "$#" -ne 2 ] && echo "usage: ./$0 /dev/video file" && return 1
ffmpeg -vd "$1" -target svcd -s 640x480 -ad /dev/dsp -ad /dev/dsp -ac 1 "$2"
}
then specify record_cam /dev/video0 /tmp/video.avi
you can fix the framerate with -fps option and put this function in another scriptshell function that will append date and hour to the file name.
To record for one hour, use the -t duration option.
Requirements for compilations
- urpmi --fuzzy libgnomeui-2.0 # for v4l2tools, will install lib64gnomeui2_0-devel-2.16.0-3mdv2007.0.x86_64.rpm (and many other devel packages, like 60 MB :/)
- urpmi --fuzzy libSDL # for luvcview, will install many development libraries for SDL
