Same thing.

For video surveillance I caputure video from a camera with:

$ /usr/local/bin/mencoder tv:// -tv driver=bsdbt848:noaudio:norm=NTSC:input=1 -nosound -o 2010-02-10.20-41-18.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=400 -really-quiet

Stop the acquisition wil a kill -TERM. The file output is:

$ file 2010-02-10.20-41-18.avi
2010-02-10.20-41-18.avi: RIFF (little-endian) data, AVI, 640 x 480, ~30 fps, video: FFMpeg MPEG-4

Best regards,

Olivier
