Coverity scan bug:
The variable will contain an arbitrary value left from earlier
computations.
Variable base_only is fetched from base-only property, and it may be
not assigned. It needs to be initialized.
Clear decoders out on a flush but keep the same instance,
rather than completely recreating them. That avoids
unecessarily freeing and recreating surface pools
and contexts, which can be quite expensive

As in gstreamer-vaapi a common base class is used, the specific
default category is passed to the base-plugin initializator, thus
the log messages are categorized with the used plugin.
Nonetheless, when the gst-debug is disabled in compilation time,
it is needed to pass NULL to the base-plugin initializator. This
patch does that.

Rename to be consistent with H.264 and also H.265 encoder. The
meson build assumed this was already consistently named, and so
previously was not able to actually build the H.265 decoder.

Use new -base API gst_video_decoder_allocate_output_frame_full() to
pass the current proxy/surface to the pool.
The pool will will export thins given surface instead of exporting a
brand new surface that will never be filled in with meaningfull data.

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.

This reverts commit 3285121181.
videodecode's negotiate() vmethod is also called when events arrive,
but this would mean that the proper configuration of sink pad might
not be complete, thus we should not update the src pad.
Let's keep the old non-vmethod negotitate().
Since the differentiation of negotiation caps and allocation caps,
there is no need to add a video crop meta with the negotiation caps.
Hence, removing it.

This is related with bug 758907 when no vaapipostproc is used (no
vaapidecodebin). In order to negotiate downstream we need to destroy
the source pad allocator, otherwise the same allocated buffers are
used, failing the mapping.
The variable member allowed_sinkpad_caps is constructed querying the
current VA display. Bearing that in mind, the variable shall be freed
when the VA display changes or is removed.
This patch moves the freeing of allowed_sinkpad_caps to close(), when
the VA display is freed.
In commit 6d11a00 were introduced a regression when gstreamer-vaapi is
compiled with out EGL/GLX support: it shall not support
GST_VAAPI_MAKE_GLTEXUPLOAD_CAPS.
This patch guards the inclusion of GST_VAAPI_MAKE_GLTEXUPLOAD_CAPS in the
allowed src caps for vaapedecode if EGL/GLX.
Just as vaapipostproc, VA decoder's context can be queried to get the possible
raw formats, so, the src caps can negotiate the exact caps that the context
supports.
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.

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.

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.

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
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.
To avoid surface-exhausted situation during reverse playback,
drop frames except for key frame.
Also, to avoid the corruption of the parser state, flush() vmethod
doesn't destroy the VA decoder when playing in reverse.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
If the backend driver vendor string is not in a white-list, and the
environment variable GST_VAAPI_ALL_DRIVERS is not set either, the decoder will
change it state from NULL to READY, hence the auto-plug mechanism will look
for another decoder.
This patch assumes the GstContext has already being shared along the pipeline
and the element has a valid GstVaapiDisplay instance.
https://bugzilla.gnome.org/show_bug.cgi?id=764673
In bug 757598 was added the set_context() vmethod chain up in
GstVaapiPluginBase. But it is buggy, since the parent_class address is
assigned to the last element which called gst_vaapi_plugin_base_class_init().
No error has shown up since none of the element's base classes redefined
set_context() vmethod from GstElement, so always the correct function was
called. Still this code is wrong and this patch make it right.
Since set_context() is the same code, a macro is used to implement that code
in all the gst-vaapi elements.
