Added two modes(as properties) for reference picture selection:
ref-mode-0: AltRef and GoldRef pointing to the recent keyframe
and LastRef is pointing to the previous frame.
ref-mode-1: Previous frame (n) as LastRef , n-1 th frame as GoldRef
and n-2 th frame as AltRef

gst_video_info_set_format() and gst_video_info_from_caps() call, internally,
gst_video_info_init(), hence it is not required to call it before them. This
patch removes these spurious calls.
This is a workaround since vaapi-intel-driver doesn't have
support for B-frame encode when utilizing low-power-enc
hardware block.
Fixme :We should query the VAConfigAttribEncMaxRefFrames
instead of blindly disabling b-frame support and set b/p frame count,
buffer pool size etc based on the query result.

The colour depth is clamped to 24 when it is not equal {15,16,24,32}. But this
fails with the NVIDIA binary driver as it doesn't advertise a TrueColor visual

work as expected.

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.

Changes since v1:
- Reworded commit message
gst_vaapi_buffer_proxy_{acquire_handle,release_handle,finalize,class}
functions are used only when libva's API version is greater than 0.36.0
This patch guards those functions completely rather than just their
content. The patch is a continuation of commit 38f8fea4

As part of the upstreaming process of gstreamer-vaapi into the GStreamer
umbrella, we need to comply with the project's code style. This meant to
change a lot of code.
It was decided to use a single massive patch to update the code style.
I would like to apologize with the original developers of this code because of
the history breakage.

This basically reverts 62c3888b76 (wayland:
decouple wl_buffer from frame).
Otherwise the frame may be overwritten while it is still used by the
compositer:
The frame done callback (frame_done_callback()) is called, when the
compositor is done processing the frame and hands it to the hardware.
The buffer release callback (frame_release_callback()) is called when the
buffer memory is no longer used.
This can be quite some time later: E.g. if weston (with the DRM backend)
puts the buffer on a hardware plane, then then buffer release callback is
called when the kernel is done with the buffer. This is usually when the
next frame is shown, so most likely after the frame done callback for the
next frame!
Since 70eff01d36 "wayland: sync() when
destroy()" the mentioned possible leak should no longer be a problem, so
reverting this change should cause no leaking buffers.

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.
This new API gst_vaapi_surface_pool_new_with_chroma_type() is for
creating a new GstVaapiVideoPool of GstVaapiSurfaces with the specified
chroam type and dimensions. The underlying format of the surfaces is
implementation (driver) defined.
When receiving the texture from the application or the video sink, we must
know it size and border. To query the texture the API has changed according to
the OpenGL version used in the GL context of the application/vsink.
This patch checks the current context API type and queries the texture
according to this detected API.

We always set GST_VAAPI_PICTURE_FLAG_SKIPPED for DECODE_ONLY frames and the
gstvaapidecoder base calss is reponsible for handling those frames later on.
No need for explicit verification of frame header's show_frame in order to
do picture outputing.
Set crop rectange if:
There is display_width and display_height which is different from actual width/height
or
The changed resolution is less than the actual configured dimension of surfaces
Unlike other decoders, vp9 decoder doesn't need to reset the
whole context and surfaces for each resolution change. Context
reset only needed if resolution of any frame is greater than
what actullay configured. There are streams where a bigger
resolution set in ivf header or webm header but actual resolution
of all frames are less. Also it is possible to have inter-prediction
between these multi resolution frames.
clang complains about a couple variables and one label which were not
used. This patch removes them.

Since gstvaapidisplay_glx.h do not expose gl.h/glx.h structures, it is not
required to include them in the header. It is not also required to include
them in gstvaapidisplay_glx.c, since gstvaapiutils_glx.h includes them and
exposes their structures (e.g. GLXPixmap).
Nonetheless, glext.h neither glxext.h are required to include, they are

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.

When the current picture has PicOutputFlag equal to 1, for each picture in the

The default scan order of scaling lists are up-right-diagonal
as per hevc specification. Use the newly implemented
uprightdiagonal_to_raster conversion codecparser APIs to
get the the scaling_list values in raster order, which is
what the VA intel driver requires.
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
in the EBUSY case.

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
