Enable the direct rendering with linear surfaces if the negotiated src caps
are video/x-raw without features.
Pass also the caps, since they are needed to know the requested caps features.
Just as we did in ensure_sinkpad_allocator(), let's move the error message
into the ensure_srcpad_allocator() from the caller,
gst_vaapi_plugin_base_decide_allocation()
Instead of receiving the GstVideoInfo structure as parameter, get the original
GstCaps from ensure_sinkpad_buffer_pool(), in this way we could decide better
which allocator instantiate.
If the allocator was configured to use direct upload or rendering, the
generated derived image created at mapping needs to be destroyed after
unmapping, because, in order to process the surface, it should not be marked
as "busy" by the driver.
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.

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.

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.

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

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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=766206
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

Since the driver checkup is done at registering, there is no need to do it

This patch tries to instantiate a GstVaapiDisplay when registering the plugin

There are two main external dependencies that define the feature set of this
plugin: a) the kernel and b) the VA driver
This patch tracks both dependencies, if any of them change, GStreamer will
re-inspect the plugin.
The kernel is tracked through the device files /dev/dri/card*
The VA driver is tracked through the files VA_DRIVERS_PATH/*_drv_video.so,
where VA_DRIVERS_PATH is the one defined in libva package configuration. Also,
the environment variables LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME are tracked
since they modify the driver lookup.
Additionally, the environment variable GST_VAAPI_ALL_DRIVERS is tracked too.

This is a fix for a regression of previous commit, which updates the filters
only when the property is set, because it is also required to update the
filter when the color balance interface change its values.
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed
In addition, updating filter is performed during reconfiguration, if needed.

The queue in GstVaapiDecode adds an extra reference to the frames. This patch
unref that extra reference earlier making the code simpler to follow.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling drain() vmethod means "decode any data it can at this point, but that
more data may arrive after". Hence, vaapidecode should check if there is data
in the output adapter and process them, without destroying the decoded picture
buffer (dpb).
Since this operation is done by gst_vaapidecode_internal_flush(), the operation
was refactored into a new function gst_vaapidecode_flush_output_adapter().
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling flush() vmethod means "to flush all remaining data from the decoder
without pushing it downstream".
Nonetheless flush() is calling gst_vaapidecode_internal_flush(), which calls
gst_video_decoder_have_frame() if there is still something in the input
adapter, which may push buffers to downstream by calling handle_frame().
This patch changes this behavior by calling gst_vaapidecode_purge() rather
than gst_vaapidecode_internal_flush(), which does what we want: flushes the VA
decoder and releases all the rest of decoded frames.

This patch is a fix for my bad review of commit 6d73ca8d. The element should
be able to return the available raw caps handled by the VA display, but that
only should happen when there a VA display. If there's none, the element
should use the caps template.

Though USE_{JPEG,VP8,VP9,H265}_ENCODER macros definition depend on USE_ENCODER
macro, it is clearer to nest them, showing explicitly the dependency relation.
Under certain conditions the element might receive a positive context query
but without a context instance. This situation will lead to a segmentation
fault when traversing the context list in the pipeline.

There's no need to check for the display in the plugin object when
decide_allocation() vmethod is called, because the display will created or
re-created along the method execution.
Get the pool config just before use it, to avoid a memory leak if the
allocator cannot be instantiated. Similarly, return FALSE if the configuration
cannot be set, avoid keep a not used allocator in the pool.
Instead of instantiating an allocator per vaapivideobufferpool, only one
allocator is instantiated per element's pad and shared among future pools.
If the pad's caps changes, the allocator is reset.

Originally, vaapivideobufferpool has a set of boolean variables for the
buffer configuration options.
This pach changes these boolean variables for a single bitwise, just as

Originally vaapivideobufferpool instantiates its own allocator regardless the
