Support for GStreamer 1.2 is obsolete. i.e. it is no longer supported.
Our goal is to support the last two stable versions of GStreamer which
are 1.4 and 1.6 at the moment.
We still keep the 1.2 specific codes until the next gstreamer-vaapi-0.7
release and will get rid of those in 0.8.
gst_buffer_copy_deep() was added in GStreamer 1.5. If want to use it we should
add an implementation if gstreamer-vaapi is linked to previous versions.

GST_CODEC_PARSER_* variables are defined if builtin codec parsers are disabled
when running configure.
Right now, libgstcodecparsers links only to libgstvaapi, but libgstvaapi_parse
need it if builtin codec parsers are disabled.
This patch adds GST_CODEC_PARSER_* variables to libgstvaapi_parse
compilation. If builtin codec parsers are enable, this variable is null, so it
should work using libgstvaapi, as normal.

Currently the H264 and H265 parsers look for MVC and SPS respectively, and
the required symbols for those were added in GStreamer 1.5
If we try to compile in GStreamer < 1.4, without enabling the builtin codec
parsers, the compilation fails, because the lack of those symbols.
This patch verifies if the installed H264 and H265 parsers have those symbols. If
they do not, the specific built in codec parsers are enabled and used.

When the GstVaapiParserInfoH264 is allocated, the memory is not initialized,
so it contains random data.
When gst_h264_parser_parse_pps() fails, the PPS structure keeps slice_group_id
pointer uninitialized, leading to a segmentation fault when the memory is
freed.
This patch prevents this by initializing the slice_group_id before the PPS
parsing.

Explicit flushing of dpb for EOS and EOB nal decoding is wrong,
the dpb_add() itself will handle the flusing(if needed) of dpb

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).

The use of gst_caps_is_always_compatible() for this optimization may lead to

Delaying the pool re-negotiation untill we push all decoded (and queued)
frames downstream. Otherwise for the multi-resolution videos, the
GstVideoVideoMemory will be having wrong resolution and which leads
to nasty behaviours, especially when using software renderers.
sample media file: RAP_B_Bossen_1.bin
case explained:
The first SPS Nal will report resoultion of 448x256 and having crop rectangles to
get the final resoultion 416x240.
Starting from 25 th frame, the resolution will change to 416x240. But parser
elements won't report this since the effective croped resolution is same in
both cases. Here the core libgstvaapi will detect this through it's internal
parsing and do all context/pool destory/reset stuffs. Also it will notify this
change to plugins in advance. But if the plugin try to do re-negotiaion of pool
immediately, this will not sync with the resolution of already decoded and queued
frames and which will lead to failure in gst_video_frame_map() in downstream(if we use the
software renderer). So we have to delay the pool renegotiation in vaapidecode,
untill we push all decoded frames downstream.

Currently we are sharing the input GstVideoCodecState with
GstVaapiDecoder(gst-libs/gst/vaapi) by just doing ref and unref for
each caps change. This is troublesome in many cases, for eg: if
resoultion changes with in a singe stream. Because, when ever there
is a resolution change, GstVideoDecoder will first change the Codec_state->caps
fields with new resolution, but since we are using the same codecstate (ref)
in gstvaapidecode.c, the caps check for input caps change will always fail.

Setting the sink to flushing causes gst_vaapi_window_wayland_sync() to
return FALSE which makes gst_vaapi_window_wayland_render() return
FALSE which ends up posting an ERROR message in
gst_vaapisink_show_frame_unlocked(). Solution is to just return TRUE

There are sometimes that the VA-API display context is not shared among the
pipeline, but it is important to know it before going to READY state (when the
pipeline is already linked).
One instance of this case is this:
gst-launch-1.0 filesrc location=media ! decodebin ! vaapipostproc ! vaapisink
This patch adds a new function in gstvaapipluginutil called
gst_vaapi_create_test_display(). Its purpose is to create a disposable VA-API
display, which only will be used for verify if the VAEntrypointVideoProc is
available by the hardware. Afterwards, it should be unrefed.
If the vaapidecodebin is going to READY state, and the element still doesn't
know if VPP is available, the last resort is to create a new instance of the
VA-API display and test for it.

First added the function gst_vaapi_video_format_get_best_native(), which
returns the best native format that matches a particular chroma type:
YUV 4:2:0 -> NV12, YUV 4:2:2 -> YUY2, YUV 4:0:0 -> Y800
RGB32 chroma and encoded format map to NV12 too.
That format is used to configure, initially, the surface's pool for the
allocator.
