Originally the drm backend only tried to open the first render node
found. But in hybrid system this first render node might not support
VA-API (propietary Nvidia driver, for example).
This patch tries all the available nodes until a finding one with a
VA-API supported driver.

In case libva-wayland has its headers not installed in default
locations (like /usr/include), the build fails to include "wayland-client.h":
CC libgstvaapi_egl_la-gstvaapiutils_egl.lo
In file included from gstvaapidisplay_wayland.h:27:0,
from gstvaapidisplay_egl.c:35:
/usr/include/va/va_wayland.h:31:28: fatal error: wayland-client.h: No such file or directory
#include <wayland-client.h>
As we already passed VA_CLAGS, /usr/include/va/va_wayland.h could be found, but it is
our fault not to instruct the system that we ALSO care for va_wayland. We correctly query
for libva-wayland.pc in configure and use this in other places as well. It is thus only
correct and consequent, to do it also at this spot.

This patch ensures to get the formats, as filter does, available in the
decoder / encoder context.
The context fills up the array as soon it is created, otherwise the pipeline
could get stalled (perhaps this is a bug in my HSW backend).

The query of all the supported formats for a VA config were only used by the
postprocessor (vaapifilter). But, in order to enable the vaapidecoder to
negotiate a suitable raw format with downstream, we need to query these
formats against the decoder's config.
This patch is the first step: moves the code in filter's ensure_image() to a
generic gst_vaapi_get_surface_formats() in vaapiutils_core, so it can be
shared later by the decoder.

When creating a GstVaapiWindowEGL, it also creates native window by its own
native display. It should pass the native display, either X11 or Wayland.

This patch is to change the inheritance of GstVaapiDisplay to GstObject,
instead of GstVaapiMiniObject. In this way we can use all the available
infrastructure for GObject/GstObject such as GstTracer, GIR, etc.
In addition, a new debug category for GstVaapiDisplay is created to make it
easier to trace debug messages. It is named "vaapidisplay" and it transverse
all the VA display backends (DRM, GLX, EGL, Wayland, ...)
This patch is a step forward to expose GstVaapiDisplay for users in a future
library.

GstVaapiDecode is a descendant of GstVaapiMiniObject, so, thought we should
use its methods, even though it doesn't change functionality.
GstVaapiPixmap, GstVaapiTexture and GstVaapiWindow are descendant of
GstVaapiObject, hence its methods shall be used.

instances when created and reuse
This patch improves performance when glimagesink uploads a GL texture.
It caches the GStVaapiTexture instances in GstVaapiDisplay{GLX,EGL}, using an
instance of GstVaapiTextureMap, so our internal texture structure can be found
by matching the GL texture id for each frame upload process, avoiding the
internal texture structure creation and its following destruction.

Implement GstVaapiTextureMap object, which caches VAAPI textures, so them can be
reused. Internally it is a hash table.
Note that it is GstObject based rather than GstVaapiObject, as part of the future
converstion to GstObject of most of the code.

We are not getting enough compression for some streams and
encoded frame end up with more size than allocated.
Assuming a compression ratio of 4, which should be good enough
for holding the frames.

While doing the mode-1 referece picture selection,
the circular buffer logic was not correctly setting the
refresh frame flags as per VP9 spec.
Make sure refresh_flag[0] get updated correclty after
each cycle of GST_VP9_REF_FRAMES.

When the format of a H.264 stream is AVC3, the SPS and PPS are inside the
stream, not in the codec_data, so the size of codec_data might be 7.
This patch reduces the minimal size of the codec_data buffer from 8 to 7.

In commit 2eb4394 the frame coding mode was verified for progressive
regardless the profile. But the FCM is only valid in the advanced
profile. This patch checks for the advanced profile before verifying FCM for
progressive.

In the earlier patch:
f31d9f3 decoder: vc1: Print error on interlaced content
Decoding would error out if the interlace flag was set in the
sequence bdu. This isn't quite right because a video can have this
flag set and yet not have any interlaced pictures.
Here instead we error out when either parsing a field bdu or
decoding a frame bdu which has fcm set to anything other than
progressive.

Validate that fps numerator is non-zero so it can be used to calculate
the duration of the B frame.
Also it gst_util_uint64_scale() is used instead of normal arithmetic in
order to aviod overflows, underflows and loss of precision.

Since the upstream of gstreamer-vaapi, the library is not a public shared
object anymore. But the EGL support depended on this dynamic library, so the
EGL support was broken.
This patch removes the dynamic library loading code and instantiates the
EGL display using either X11 or Wayland if available.

This reverts commit 1dbcc8a0e1 and commit
372a03a9e3.
While the dmabuf handle is exported, the derive image must exist, otherwise
the image's VA buffer is invalid, thus the dmabuf handle is never released,
leading into a file descriptors leak.
A planar(or some other) buffer allocation may fail on the driver, then
the wayland connection becomes invalid, not able to send request or
receive any event. So we need to set up a new wayland connection if
there's an error detected on the cached wl_display.

Change defaults for max-bframes, cabac, and dct8x8 to be enabled
by default. This will cause the default profile to be high instead
of baseline. In most situations this is the right decision, and
the profile can still be lowered in the case of caps restrictions.

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.
