Currently, v4l2videodec probe for HW decoder by iterating /dev/videoN, starting
as zero. If /dev/video0 does not exist, it fails to find a decoder. This seems
like the wrong way to enumerate the devices, still need to find the right way,
if anyone have information. Is using udev might be an option ?
