a7a9b33ad9 Implement decoder reset on flush, rather than recreating
Clear decoders out on a flush but keep the same instance,
rather than completely recreating them. That avoids
unecessarily freeing and recreating surface pools
and contexts, which can be quite expensive

d6738f3f93 libs: decoder: h264,h265 avoid uninitialized variable
Configuring GCC to verify possible usage of uninitialized variables,
shows that found_index might be used without previous assignation.

This patch assigns a initial value to found_index, also avoid a
branching when returning the result value.

d9ef88230f decoder: h265: handle the SEI NAL units included in codec_data
The prefix/suffix SEI nal units can appear in codec_data too
which weren't handled before. Parse these SEI headers to

05cf583c97 decoder: h265: fix to release all dpb pictures
Without this, all dpb pictures are not released during flush,
because we used the global dpb_count variable for checking the
dpb fullness which get decremented in dpb_remove_index()
routine during each loop iteration.

ffd5028a38 decoder: hevc: Fill dependent slice segment headers while parsing
Copy the data into the dependent slice segment header from the
corresponding independent slice segment header during parsing.

Previously the reference to the "previous" independent header was
held through the parsing phase and then dereferenced during the
decoding phase. This caused all dependent headers to be populated
with the data of the AU's last independent header instead of the
proper corresponding header.

61045041c4 Add 10 HEVC 10 bit decoding support
Only supporting vaapidecode ! vaapisink combination for now.

Missing dependencies:
1: No support for P010 video format in GStreamer
2: No support for P010 vaGetImage()/vaPutimage() in vaapi-intel-driver
3: As a result of 1&2 , we have no support for Vaapi Video memory mapping
   through GstVideoMeta.

Right now we only set chroma format (YUV420 with more than 8 bits per channel)
for surface pool and keeping GST_VIDEO_FORMAT as ENCODED. The underlying format
of the surfaces is implementation (driver) defined, which is P010.

3bd6185f9f decoder: hevc: Don't flush dpb for EOS/EOB nal

8799a8044d decoder: hevc: Fix the picture addition in dpb() based on spec H265 v3 (04/2015)
This fix is based on the V3 vesion of spec which was missing in older versions.

When the current picture has PicOutputFlag equal to 1, for each picture in the
DPB that is marked as "needed for output" and follows the current picture in output order,
the associated variable PicLatencyCount is set equal to PicLatencyCount + 1 (C.5.2.3).

95b8ca0cda decoder: hevc: Workaround to recognize wrongly encoded main profile streams
HACK: This is a work-around to identify some main profile streams having wrong profile_idc.
There are some wrongly encoded main profile streams(eg: ENTP_C_LG_3.bin) which doesn't
have any of the profile_idc values mentioned in Annex-A, instead general_profile_idc
has been set as zero and having general_profile_compatibility_flag[general_profile_idc]
is TRUE. Assuming them as MAIN profile for now.

696b446f09 decoder: hevc: Fix decoding of stream when it has temporal sublayers
We are calculating the dpb size based on max_dec_pic_buffering.
But if there are more than one temporal sublayers, we are supposed
to use the max_dec_pic_buffering[max_sub_layers_minus] for dpb
size calculation (Assuming HighestTid as max_sub_layers_minus).

Sample streams: TSCL_A_VIDYO_5.bin, TSCL_B_VIDYO_4.bin
