Implements gst_vaapi_utils_h26x_write_nal_unit(), which writes NAL
unit length and data to a bitwriter.
Note that this helper function applies EPB (Emulation Prevention
Bytes), since otherwise produced codec_data might be broken when
decoder/parser considering EPB, starts parsing.
See sections 7.3 and 7.4 of the H264 and H264 specifications, which
describes the emulation_prevention_three_byte.

From man open(2):
The O_CLOEXEC, O_DIRECTORY, and O_NOFOLLOW flags are not specified
in POSIX.1-2001, but are specified in POSIX.1-2008. Since glibc
2.12, one can obtain their definitions by defining either
_POSIX_C_SOURCE with a value greater than or equal to 200809L or
_XOPEN_SOURCE with a value greater than or equal to 700. In glibc
2.11 and earlier, one obtains the definitions by defining
_GNU_SOURCE.
And indeed, with the uClibc C library, O_CLOEXEC is not exposed if
_GNU_SOURCE is not defined. Therefore, this commit fixes the build of
gstreamer-vaapi with the uClibc C library.

The encoder should be able to change its caps even it is already
processing a stream.
This is suppose to happen after a flush so the codedbuf_queue should

This patch adds a GstMemory as a variable member of the buffer proxy,
because we will need to associate the buffer proxy with the memory
which exposes it. Later, we will know which memory, in the video buffer
pool, is attached to the processed surface.

Thus, when generating the allowed caps, the element will throw a
warning and it will use its caps template.
This behavior might be a bug in the VA driver.

When a new sink caps arrive the internal decoder state is updated
and, if it is, request a downstream renegotiation.
Previously, when new caps arrived the whole decoder where destroyed
and recreated. Now, if the caps are compatible or has the same codec,
the internal decoder is kept, but a downstream renegotiation is
requested.

Redirect libva's logs to GStreamer logging mechanism. This is
particularly useful when VA is initialized, because it always logs

In order to achieve this a new helper function was added as a wrapper

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

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

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

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.

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.
