Comment (by holden):

 Thanks Carl.

 I only wanted to add that if llarevo wants to test again with latest git
 head, the correct command to try is not:

 {{{
 ffmpeg -loglevel debug -f v4l2 -s vga -r 25 -i /dev/video0 out-vga-2M-
 5min.mpg
 }}}

 but:

 {{{
 ffmpeg -loglevel debug -f v4l2 -video_size vga -framerate 25 -i
 /dev/video0 out-vga-2M-5min.mpg
 }}}

 Options '-s' and '-r' are not valid options for v4l2 input device. To see
 the list of options please go to: [http://ffmpeg.org/ffmpeg-devices.html
 #video4linux2_002c-v4l2]

 Also, as I said earlier, using '-framerate 25' or not should not make any
 difference, since the framerate is fixed by a particular standard (like
 PAL or NTSC) and cannot be changed usually.
