May I ask for one more trace ? I'd like to see the sequence number when it
works (in 1.2). I'd like to see the sequence number, it's in a trace that
starts with "dequeued buffer".

Yes, it's something that I'll address in GStreamer. I don't know why you have a
corrupted buffer, but we should recover as state by the spec:

"When this flag is set, the buffer has been dequeued successfully, although the
data might have been corrupted. This is recoverable, streaming may continue as
normal and the buffer may be reused normally. Drivers set this flag when the
VIDIOC_DQBUF ioctl is called."
