Hi Rodney!
Thanks for your quick answer.
I have built another system install development packages (headers gcc make
...) get latest git version. But not even worth :(
This is the command:

$ ffmpeg -v verbose -i /dev/video0 -f video4linux2 -s 640x480 -r 25
out10.avi 2>&1 | tee -a ffmpeg-grab.log

and this is the console output:
ffmpeg version N-38750-g599888a Copyright (c) 2000-2012 the FFmpeg developers
  built on Mar 12 2012 23:50:31 with gcc 4.4.5
  configuration: --enable-nonfree --enable-libv4l2
  libavutil      51. 42.100 / 51. 42.100
  libavcodec     54. 10.100 / 54. 10.100
  libavformat    54.  2.100 / 54.  2.100
  libavdevice    53.  4.100 / 53.  4.100
  libavfilter     2. 64.101 /  2. 64.101
  libswscale      2.  1.100 /  2.  1.100
  libswresample   0.  7.100 /  0.  7.100
/dev/video0: Invalid data found when processing input

What could be missed?
Sincerely
