Hi,
Thanks for the tip, but at first instance, doesn't works, when i try to
parse any parameter/command the video stops and image get breaked and
crappy, but no audio/sound, also, here is the list output:
$ v4lctl -c /dev/video0 list

-----------+--------+---------+---------+-------------------------------------
norm | choice | PAL-DK | PAL | PAL PAL-BG PAL-I PAL-DK NTSC SECAM
PAL-M PAL-Nc PAL-60

audio mode | choice | mono | mono | mono stereo lang1 lang2
