Hello again,
I've found how to capture video using xawtv (or streamer), but so far it
does not works for me. For any file format xawtv says the following:
ioctl: VIDIOC_REQBUFS(count=2;type=VIDEO_CAPTURE;memory=MMAP): Invalid
argument
ioctl: VIDIOC_REQBUFS(count=1;type=VIDEO_CAPTURE;memory=MMAP): Invalid
argument
no way to get: 384x288 12 bit YUV 4:2:0 (planar)
