I've modified your included test code to use V4L2_PIX_FMT_BGR24 instead of V4L2_PIX_FMT_YUYV. Attempting to set the new pixel format with ioctl and VIDIOC_S_FMT does not cause an erroneous return value. However, subsequently calling ioct...

V4L2_PIX_FMT_SGRBG12 which strangely enough used the same fourcc, even though that fourcc made no sense for a Bayer format. In any case, you can't have duplicates, so change the fourcc of V4L2_PIX_FMT_BGRA444. Signed-off-by: Hans Verkuil <hverkuil-ci...@xs4all.nl> ...
