Hi Pawel, Hans,
I think we talked some time ago on IRC about this patch.
If I remember correctly, the conclusion was that it would be better to use
a specific pixel formats for this kind of out codec output.
Akin to:
V4L2_PIX_FMT_H264 'H264' H264 video elementary stream
with start codes.
V4L2_PIX_FMT_H264_NO_SC 'AVC1' H264 video elementary stream without
start codes.
Could you confirm this?
Best wishes,
