49f200cb54 h264parse: Improved AU boundary detection
- AU boundary detection reviewed to follow more closely H.264 spec. and more
  specifically clauses 7.4.1.2.3 and 7.4.1.2.4.
- The gist of the changes is a look-a-head in then next AU required identify the
  last vcl-nal of current AU and firt vcl-nal of next AU (according to
  7.4.1.2.4) followed by the identification of the first nal of next AU
  (according to 7.4.1.2.3).
- A backlog of all nals of current AU and next AU up to the point where current
  AU can identified completed is kept.
- In NAL alignement mode vcl-nal are sent immediatly but the history is kept to
  allow AU boundary detection. Non-vcl-nal can be delayed up to the reception of
  the next vcl-nal to allow a correct AUD insertion.
- Based on this improved AU boudary detection we can avoid erronous AUD
  insertion, like the one highlighted by test
  test_parse_sliced_with_prefix_and_sei_nal_au.
- Add support for MVC AU boundary detection. (H.7.4.1.2.4)
- Explicitly report SVC not supported. We don't have the SVC NAL parsing
  required to identify boundary. (missing dependency_id and quality_id fields
  from SVC, see G.7.4.1.2.4)

b092c3f580 h264parse: adjust some logs printing level in h264parse
adjust log level from GST_ERROR to GST_WARNING when h264 caps have
codec_data but no avc format or have no codec data or stream-format.
Because theses are not real errors, it is easy to mislead if print error
logs.

9deb3d6aa4 h264parse: Stop considering NO_NAL as an error
The NO_NAL return value simply means that the buffer did not contain
enough data to identity a NAL. This should lead to waiting for more data not
considering the stream as invalid.

ad30fb87c2 h264parse: Validate VUI framerate
A few streams contain invalid/wrong framerate in VUI. Do validate
it based on the spec and ignore invalid VUI framerate values.

dae73d6686 h264parse: Add the missing timestamp when splitting a frame.
When splitting a frame, the gst_buffer_copy_region() does not copy
the timestamp correctly for sub frames when the offset is not 0.
We still need those timestamps for each output sub frame.

cb8da91f7a h264parse: Include coded-picture-structure info in caps
This reverts commit 652773de36 and
modifies it to rename the caps field name to coded-picture-structure.

It was previously removed because it confuses the decoder and we didn't
have a valid use case for including it in the encoded caps at this
stage. We now do have such a use case but still don't want to confuse
the decoder, so the field is renamed.

However, it is still not accurate without looking at the SEI picture
structure of each frame, so it was named coded-picture-structure. If its
value is "frame" it is most likely progressive, if it's "field" it is
most likely interlaced or mixed.

21d7bd09ce h264parse: Don't insert extra AUD if exists in bitstream already
AUD nalu in packetized format is completely valid and therefore we should not
assume that we should insert AUD for packetized -> bytestream
conversion.
