The way to experiment with the direct rendering is through and internal
compiler pre-processor flag.
The current change set enables a way to specified at run-time, as a flag
passed to the allocator at instanciation time.
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.

Since vaapipostproc is only registered if the driver supports it, all the
support for dynamic loading were removed. Though some leftovers remained.

In the spirit of the codec split, this patch removes the documentation of
vaapidecode and adds a page per each possible decoder.
Nonetheless, only those available in the compilation system are going to be
instrospected, because the rest are not registered.
vaapidecode has a member named allowed_caps, but this name is not enough
explicit. This patch renames allowed_caps to allowed_sinkpad_caps.
No functional changes were included.

In order to clarify the use of flag as input parameter, it is renamed to
surface_alloc_flag, since it is used when creating a VA surface with certain
properties.

When caps reconfiguration is called, the new downstream frame size might be
different. Thus, if the downstream caps change,the display's texture map is
reset.
In addition, during pipeline shutdown, textures in texture map have to be
released, since each one have a reference to the GstVaapiDisplay object, which
is a dangerous circular reference.

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.

set_format() is called by upstream when the stream capabilites has changed.
Before, if the new stream is compatible with the old one the VA decoder was
not destroyed. Nonetheless, with this behavoir, the VA decoder ignores
when the upstreamer parsers gets more details of the stream, such as the
framerate. Hence, when the src caps are negotiates, the further sink caps
updates are ignored.
This patch forces the VA decoder destroying and recreation when set_format()
is called.

When calling gst_video_frame_map() with GST_MAP_WRITE flag, it doesn't call
ensure_image_is_current(), which means it doesn't guarentee VAImage is valid
in this case.

In a multiple video cards system, a X11 environment may have different VA
capabilities. This patch tracks the DISPLAY environment variable to
invalidates the GStreamer features cache. Also tracks WAYLAND_DISPLAY.

Encoders claim to support a whole bunch of input formats but then
just error out if the format is not actually supported, even if
there's a converter in front. This means they're not fit for
autoplugging in encodebin or camerabin yet and therefore should
not have a rank. People can still use them in custom pipelines.

Check earlier if upstream video source has activated the dmabuf-import
io-mode (hack to disappear soon), thus we can avoid the re-assignation of a
new allocator.
Add the method gst_allocator_get_vaapi_image_size() for the
GstVaapiVideoAllocator, which gets the size of the allocated images with the
current video info.
This method replaces the direct call to the allocator's image info when the
pool is configured.
Depends on media, video size is sometimes updated with new allocator.
It leads to dismatch between bufferpool's set size and real allocated buffer size.
In this case, it causes every buffer is freed during release in bufferpool,
which should be reused. This affects performance.

In order to register only the available decoders, this patch queries the
created test VA display, which uses the currently used back-end (X11, Wayland,
DRM, …) on the used display device.

Split the vaapidecode to all the supported codecs with the format
vaapi{codec}dec.
vaapidecode is stil registered as a GObject type, but not as a
GStreamer feature, so it can be used internally by vaapidecodebin without
changing its code too much.

Since the elements dependant of the VA video processor are now only registered
if it is available, vaapidecodebin code can be simplified a lot, removing all
the code required to check if the VA video processor was available.

Delay the GstVaapiDisplay instantiating until when changing the state from
READY to PAUSE. In this way the element has more chances to find an already
created GstVaapiDisplay, or a GL context, in the pipeline.

The function gst_vaapi_create_display_from_gl_context() cretes a
GstVaapiDisplay given a GstGLContext. But it didn't created a GLX VA display
when the GL platform was GLX, but a plain X11 VA display.
This patch fixes that, by querying the GL platform earlier.

Using the GstContext mechanism, it is possible to find if the pipeline
shares a GstGLContext, even if we are not to negotiating GLTextureUpload
meta. This is interesting because we could negotiate system memory caps
feature, but enable DMABuf if the GstGLContext is EGL with some extensions.

Since the driver checkup is done at registering, there is no need to do it
when changing the element state from NULL to READY. This patch remove this
vmethod from vaapidecode.
Query the GstVaapiDisplay to know if the driver supports video
postprocessing. If does, then register vaapipostproc and vaapidecodebin
elements.
This patch will simplify the design of vaapidecodebin.
