The VP9 spec defines the MAX_TILE_WIDTH_B64(64), which is the maximum
width of a tile in units of superblocks. So the max width of one tile
should not be larger than 64x64=4096. When the width exceeds 4k, we
need to split it into multiple tiles in columns. The current vp9 encoder
does not handle this correctly.
The command such as:
gst-launch-1.0 videotestsrc ! video/x-raw,width=7680,height=4320 ! \
vaapivp9enc ! fakesink
will crash.

Currently the default drm device is always used on a system with
multiple drm devices. This patch allows user to specify the required
drm device via GST_VAAPI_DRM_DEVICE env variable
Example:
GST_VAAPI_DRM_DEVICE=/dev/dri/renderD129 gst-launch-1.0 videotestsrc !
vaapih264enc ! fakesink

drmGetBusid() (GET_UNIQUE ioctl) won't return a valid bus id when
drmSetInterfaceVersion() (SET_VERSION ioctl) hasn't been called(see[1]),
so we can't get the right device path. Running test-display will get the
error below:
** (test-display:18630): ERROR **: 10:26:00.434: could not create Gst/VA
display
Calling drmSetInterfaceVersion() before drmGetBusid() can't fix this
issue because a special permission is required for SET_VERSION ioctl.
This patch retrieves the device path from file descriptor via
g_file_read_link()

Texture upload mechanism used by gstreamer-vaapi relies on 8 bpc.
In latest mesa versions the first fbconfig might not be 8 bit, so iterate
over it to find the correct config with supported values.
This also adds 8 bit alpha size to the framebuffer configuration which is
required to get it working properly.

The AV1 film_graim feature needs two surfaces the same time for
decoding. One is for recon surface which will be used as reference
later, and the other one is for display. The GstVaapiPicture should
contain the surface for display, while the vaBeginPicture() need
the recon surface as the target.
We add a gst_vaapi_picture_decode_with_surface_id API to handle this
kind of requirement.

gst_vaapi_encoder_h264_get_pending_reordered() does not consider the
case for HIERARCHICAL_B mode. The pipeline:
gst-launch-1.0 videotestsrc num-buffers=48 ! vaapih264enc prediction-type=2 \
keyframe-period=32 ! fakesink
get a assert:
ERROR:../gst-libs/gst/vaapi/gstvaapiencoder_h264.c:1996:reflist1_init_hierarchical_b:
assertion failed: (count != 0)
The last few B frames are not fetched in correct order when HIERARCHICAL_B
is enabled.
We also fix a latent bug for normal mode. The g_queue_pop_tail() of B frames
make the last several frames encoded in reverse order. The NAL of last few
frames come in reverse order in the bit stream, though it can still output
the correct image.

In scc mode, the I frame can ref to itself and it needs the L0 reference
list enabled. So we should set the I frame to P_SLICE type. We do not need
to change the ref_pic_list0/1 passed to VA driver, just need to enable the
VAEncPictureParameterBufferHEVC->pps_curr_pic_ref_enabled_flag to notify
the driver consider the current frame as reference. For bits conformance,
the NumRpsCurrTempList0 should be incremented by one to include the current
picture as the reference frame. We manually do it when packing the slice header.
Command line like:
gst-launch-1.0 videotestsrc num-buffers=10 ! \
capsfilter caps=video/x-raw,format=NV12, framerate=30/1,width=640,height=360 ! \
vaapih265enc ! capsfilter caps=video/x-h265,profile="{ (string)screen-extended-main }" ! \
filesink location=out.265
Can be used to specify that the encoder should use SCC profiles.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/-/merge_requests/379>
We need the allowed_profiles to store the allowed profiles in down
stream's caps.
Command line like:
vaapivp9enc ! capsfilter caps=video/x-vp9,profile="{ (string)1, \
(string)3 }"
We need to store GST_VAAPI_PROFILE_VP9_1 and GST_VAAPI_PROFILE_VP9_3
in this list.

We now use gst_h265_get_profile_from_sps() to replace the old way
of gst_h265_profile_tier_level_get_profile() to get more precise
profile. The new function consider the unstandard cases and give
a more suitable profile decision.

The removed code set all the reference frames to the current frame it is a key
one, but later, all the reference frames were rewritten with the decoded picture
buffers or VA_INVALID_SURFACE if they were not available.
Basically, all this time the first reference frame assignment has been ignored,
and it's not described by the spec, and this patch removes that code.

This code path is used when frames are rendered as textures through
GstVideoGLTextureUploadMeta with EGL, mainly under Wayland.
Originally the EGLImage was exported as GEM, which was handled by
Intel drivers, but Gallium ones cannot create VA surfaces from
GEM buffers, only DMABuf.
This patch checks the memory types supported by VA driver to choose
the render the EGLImages from GEM or DMABuf, because GEM is still
better where supported.
DMABuf is well handled either by intel-vaapi-driver and gallium.
Fixes: #137

Some buffers and the associated FrameState state may still be pending at
that point. If the wayland connection is shared, then messages for the
buffer may still arrive. However, the associated event queue is already
deleted. So the result is a crash.
With a private connection the associated memory is leaked instead.

gst_vaapi_window_wayland_set_render_rect() may be called from an arbitrary
thread. That thread may be responsible for making the window visible.
At that point another thread will block in gst_vaapi_window_wayland_sync()
because the frame callback will not be called until the window is visible.
If that happens, then acquiring the display lock in
gst_vaapi_window_wayland_set_render_rect() would result in a deadlock.
Cache the size of the opaque rectangle separately and create the opaque
region right before applying it to the surface.

Implements new vmethod gst_vaapi_window_set_render_rectangle,
which is doing set the information of the rendered rectangle set by
user.
This is necessary on wayland at least to get exact information of
external surface.
And vaapisink calls this when gst_video_overlay_set_render_rectangle is
called.

The Wayland sub-surfaces API is used to embed the video into an application
window.
See Appendix A. Wayland Protocol Specification as the following.
"""
The aim of sub-surfaces is to offload some of the compositing work
within a window from clients to the compositor. A prime example is
a video player with decorations and video in separate wl_surface
objects.
This should allow the compositor to pass YUV video buffer processing to
dedicated overlay hardware when possible.
