media: v4l2: Reorder field reflist

2022-05-17T08:03:11Z

As per spec, the field reflist requires interleaving top and bottom field in a specific way that does not fit inside the sort operation. The process consist of alternating references parity, starting with a reference of the same parity as the current picture. This processs is done twice, once for short term references and a second time for the long term references.

media: h264: Sort p/b reflist using frame_num

2022-05-17T08:02:29Z

In the reference list builder, frame_num refers to FrameNumWrap in the spec, which is the same as the pic_num for frame decoding. The same applies for long_term_pic_num and long_term_frame_idx. Sort all type of references by frame_num so the sort can be reused for fields reflist were the sorting is done using frame_num instead. In short, pic_num is never actually used for building reference lists. Signed-off-by: Nicolas Dufresne Reviewed-by: Sebastian Fricke Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

2022-05-17T08:01:48Z

Add debug print statements to print the content of P & B reference lists, to verify that the ordering of the generated reference lists is correct. This is especially important for the field decoding mode, where sorting is more complex.

When the current picture is a field, store each field into the unordered_list and preserve both top and bottom picture order count. Signed-off-by: Nicolas Dufresne Reviewed-by: Sebastian Fricke Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

This is to accommodate support for field decoding, which splits the top and the bottom references into the reference list. Signed-off-by: Nicolas Dufresne Reviewed-by: Sebastian Fricke Reviewed-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: h264: Use v4l2_h264_reference for reflist

2022-05-17T07:58:42Z

In preparation for adding field decoding support, convert the byte arrays for reflist into array of struct v4l2_h264_reference. That struct will allow us to mark which field of the reference picture is being referenced.

media: uapi: Add IPU3 packed Y10 format

2022-05-17T07:36:03Z

Some platforms with an Intel IPU3 have an IR sensor producing 10 bit greyscale format data that is transmitted over a CSI-2 bus to a CIO2 device - this packs the data into 32 bytes per 25 pixels. Add an entry to the uAPI header defining that format. Signed-off-by: Daniel Scally Acked-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: h264: Avoid wrapping long_term_frame_idx

2022-05-13T12:59:54Z

For long term references, frame_num is set to long_term_frame_idx which does not require wrapping. This is fixed by observation, no directly related issue have been found yet.
