4a93f6e651 h265parse: recognize more HEVC extension streams
There are streams which have the right general_profile_idc and
general_profile_compatibility_flag, but don't have the right extension
flags. We may try to use chroma_format_idc and bit_depth to
recognize these streams.

e.g.

626af12498 h265parser: select the right profile for high throughput SCC stream
Currently screen-extended-high-throughput-444 is recognized as
screen-extended-main-444, screen-extended-high-throughput-444-10 is
recognized as screen-extended-main-444-10 because they have the same
extension flags, so without this patch, it is possible that a decoder
which supports SCC but doesn't support throughput SCC will try to decode
a throughput SCC stream.

e.g.
https://www.itu.int/wftp3/av-arch/jctvc-site/bitstream_exchange/draft_conformance/SCC/HT_A_SCC_Apple_2.zip

7f10f8a93e codecs: vp9decoder: Relying on upstream vp9parse for super frame handling
By this way, we can simplify the decoding flow. Moreover, we don't
need to worry about the case where multiple visible-frames are
composed in one super-frame, since upstream vp9parse will split
them per frame unit.

6523c5bcb6 h264decoder: Add ability to lookup by system_frame_number
This is to avoid having to create a reference chain in decoders from
GstVideoCodecFrame to GstH264PIcture to implementation wrapper.

So this change introduces:

 - gst_h264_dpb_remove_outputed (dpb)
 - gst_h264_dpb_get_picture(dpb, system_frame_num)
 - gst_h264_decoder_get_picture (dec, system_frame_num)

In order to ensure that frames can be looked up during the draining
process, we now first remove all (including reference) frames that
have been outputed but are still in the DPB. Then for each remaining
buffers, we remove it from the DPB to reach reference 1 and output it.

Previously we could take all not outputed outside of the DPB which would
prevent lookup by the base class.

82fb55bdff codecs: h264decoder: Make GstVideoCodecFrame hold the last reference of the buffer
... when gst_video_decoder_finish_frame() is called.

Some subclasses attach GstBuffer to GstH264Picture as an user data
which will increase reference count of the buffer. It would result
to buffer copy per every frame.

Background here is, GstVideoDecoder wants writable output buffer for
GstMeta handling, and if the output buffer is not writable
(i.e., reference count is not one), the buffer will be copied.
Even if underlying GstMemory wouldn't be copied, buffer copy operation
will introduce extra memory allocation overhead which is not optimal.

By this modification, subclass might be able to receive the last
reference to GstH264Picture

9ff332e15d codecs: h264decoder: update max_dpb_frames only if VUI is present
There are some streams, with HRD, where the the calculated
max_dpb_frames is zero (max_dpb_mbs is less than size mb). In order to
get the dbp size it is required to rely on the VUI parameters if they
are present.

According to the spec Annex E.2.1

**max_dec_frame_buffering** specifies the required size of the HRD
decoded picture buffer (DPB) in units of frame buffers.  It is a
requirement of bitstream conformance that the coded video sequence
shall not require a decoded picture buffer with size of more than
Max(1, max_dec_frame_buffering) frame buffers to enable the output of
decoded pictures at the output times specified by dpb_output_delay of
the picture timing SEI messages. The value of max_dec_frame_buffering
shall be greater than or equal to max_num_ref_frames. An upper bound
for the value of max_dec_frame_buffering is specified by the level
limits in clauses A.3.1, A.3.2, G.10.2.1, and H.10.2.

When the max_dec_frame_buffering syntax element is not present, the
value of max_dec_frame_buffering shall be inferred as follows:

– If profile_idc is equal to 44, 86, 100, 110, 122, or 244 and
constraint_set3_flag is equal to 1, the value of
max_dec_frame_buffering shall be inferred to be equal to 0.

– Otherwise (profile_idc is not equal to 44, 86, 100, 110, 122, or 244
or constraint_set3_flag is equal to 0), the value of
max_dec_frame_buffering shall be inferred to be equal to MaxDpbFrames.
