b93315fa6c codecparsers: Exclude the size of obu_size when identify OBU.
obu->obu_size does not contain the bytes of obu_size itself, we need
to exclude it when doing the saint check.

33fcb0faf0 codecparsers: av1: add the set_operating_point() API.
The av1 can support multi layers when scalability is enabled. We
need an API to set the operating point and filter the OBUs just
belonging to some layers(the layers are specified by the operating
point).

c4aaeb0509 codecparsers: av1: Add an API to reset the annex_b state only.
In practice, we encounter streams that have one or more temporal units
error. When that kind of error temporal units is in annex b format, the
whole temporal unit should be discarded.
But the temporal units before it are correct and can be used. More
important, because of the error temporal unit, the parser is in a wrong
state and all later temporal unit are also parsed uncorrectly.
We need to add this API to reset the annex_b state only when we meet
some temporal unit error.

a4f459fe21 codecparsers: av1: clean the seen_frame_header in parse_tile_group().
The current seen_frame_header is not cleaned correctly. According
to the spec, it should be cleaned when tiles are parsed completely.
Also delete a verbose seen_frame_header init in reset_state().

227d7a9327 codecparsers: av1: Do not assert in identify_one_obu when check annex b size.
Some buggy stream just writes the wrong temporal unit and frame size in
the stream. We should return failure rather than assert to abort.

0d4982a3d5 codecparsers: av1: Improve the parse_tile_info.
1. store more tile info when parse tile group.
   The column, row, tile offset and tile data size are all useful for
   decoder process, especially for HW kind decoder such as VAAPI dec.
   Also fix the tile group skip size for each tile data.
2. No min_inner_tile_width requirement in newest spec.
3. Calculate the sbs of each tile for both uniform tile and non-uniformi
   tile.

2fd1da60ea codecparsers: av1: add valid check for global motion params.
The global motion params and its matrix values need to be verified
before we use them. If it is invalid, we should notify the decoder
that it should not be used.

fce380ec40 codecparsers: av1: Improve the loop filter setting.
1. loop_filter_ref_deltas should be int because it needs to compare
   with 0.
2. Move the loop filter init logic to setup_past_independence() and
   load_previous(), which make it more precise with the spec.

f20798a1db codecparsers: av1: Fix a error report for metadata obu.
The metadata OBUs, for example, ITUT_T35 has an undefined payload such
as itu_t_t35_payload_bytes field in AV1 spec, which may cause the failure
of parsing the trailings bits. We can give a warning and ignore this kind
of errors.

algorithm. We also need to init them to -1.

13d55627f0 libs: parser: Adds AV1 parser.
This is the first version of AV1 parser implementation in GStreamer.

A test file is also provied with several test cases. It contains a
test sequence taken from the aom testdata set, with one key and one
inter-frame. The same test sequence has been reencoded to annexb.

testdata is taken from aom testdata (and reencoded for annexb) as well
as handcrafted testcases. Once reference testdata is available, the
testing could be imporved aswell.
