6f2ab31d10 h265parser: Calculate short term RPS size in slice header
The calculated size of short_term_ref_pic_set is not a part of
HEVC syntax but the value is used by some stateless decoders
(e.g., vaapi, dxva, vdpau and nvdec) for the purpose of skipping
parsing the syntax by the accelerator.

4bc46b902d h265parse lib: fix missing condition when parse PPS
Follow h265 spec(04/2015), log2_max_transform_skip_block_size_minus2

18b54f8d34 h265parser: Skip unused SEI bits differently
3-byte emulation bytes can confuse the current code that skips
bits at the end of an SEI. Use a simpler method that's also
quicker because it skips all remaining bits in one go instead
of 1 bit at a time.

When the timeing_info is present in the VPS, vui_timing_info
, when present, shall be equal to vps_timing_info, and when
not present, is inferred to be equal to vps_timing_info.

52f2054386 h265parser: Various update of vps parsing
* Add FIXME for future correction of HRDParames parsing.
Spec. defines that the number of HRDParames could be up to
"vps_num_layer_sets_minus1 + 1" (i.e., 1024).

* Add parsing vps_base_layer_{internal,available}_flag.

* Fix possible invalid vps_extension parsing.

7d1be36561 h265parser: Stop considering 6 bytes NAL complete
This is only TRUE for EOS / EOB NALs. Before this patch, passing
any valid 6 bytes of a NAL would make the parser pretend this NAL is

d252f503fc h265parser: decouple GstH265Profile and GstH265ProfileIDC
We used to have the same enum to represent H265 profiles and idc values.
Those are no longer the same with extension profiles defined from
version 2 of the spec.
Split those enums so the semantic of each is clearer and we'll be able
to add extension profiles to GstH265Profile.

Also add gst_h265_profile_tier_level_get_profile() to retrieve the
GstH265Profile from the GstH265ProfileTierLevel. It will be used to
implement the detection of extension profiles.

c8b3d84757 codecparser: h265: initialize parsing structures
Initialize to 0 these parse structures before filling them: GstH265SEIMessage,
GstH265NalUnit, GstH265VPS, GstH265PPS, GstH265SPS and GstH265SliceHdr.

When calling the functions which fill those structures, they may fail, leaving
unitialized those structures. This situation may lead to future problems, such
as a segmentation fault when freeing, for example.

This patch initializes to zero these structures, before filling them.

fcd42b7d77 codecparsers: h265: Fix the selection of Active Ref Pic Set
If short_term_ref_pic_set_sps_flag is FALSE, the ShortTermRefPicSet
structure is supposed to derive from slice header. Which means,
CurrRpsIdx is equal to num_short_term_ref_pic_sets. But the number
of refpicsets communicated via sps header is only num_short_term_ref_pic_sets - 1.
And we are using slice_header structure to reference the last entry, which is
ShortTermRefPicSet[num_short_term_ref_pic_sets].

8a6cc4ed27 codecparsers: h265: Fix the range of delta_chroma_log2_weight_denom
ChromaLog2WeightDenom = luma_log2_weight_denom + delta_chroma_log2_weight_denom

The value of ChromaLog2WeightDenom should be in the range of 0 to 7 and
the value luma_log2_weight_denom  should be also in the range of 0 to 7.
Which means , delta_chroma_log2_weight_denom can have values in the range
between -7 and 7.
