If a GstVaapiDisplay is not found in the GStreamer context sharing,
then VAAPI elements look for a local GstGLContext in gst context
sharing mechanism ('gst.gl.local.context').
If this GstGLContext not found either then, only the VAAPI decoders
and the VAAPI post-processor, will try to instantiate a new
GstGLContext.
If a valid GstGLContext is received, then a new GstVaapiDisplay will
be instantiated with the platform, API and windowing specified by the
instantiated GstGLContext.

Every time a new buffer is allocated, the pool is activated. This
doesn't impact in performance since gst_buffer_pool_set_active()
checks the current state of the pool. Nonetheless it logs out a
message if the state is the same, and it floods the logging subsystem
if it is enabled.
To avoid this log flooding first the pool state is checked before
changing it.
Adds two buffers as the default value of minimum buffer.
This would be used when creating and proposing vaapi bufferpool for
sink pad, hence the upstream element will keep, at least, these two
buffers.

First, deactivate source pad pool when the out caps change, and if so,
destroy texture map, the source pad allocator and pool only if the
new caps are different from the ones already set.
This patch adds the created allocator to the allocation query either
in decide_allocation() and propose_allocation() vmehtods.
With it, there's no need to set the modified allocator's size in the
pool configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=774782
When the allocator is created, it stores the allocation caps. But sometimes
the "allocation caps" may be different from the "negotiation caps".
In this case, the allocator should store the negotiation caps since they
are the ones used for frame mapping with GstVideoMeta.
When vaapispostproc is used, this is not a problem since the element is assume
to resize. But when using a vaapi decoder only, with a software renderer, it
fails in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=773323
Since when the sink pad allocator is created, it is decided if the required
one is vaapi allocator or dmabuf allocator, there is no need to force its set
again.
When running gst-discoverer-1.0, in certain media, vaapipostroc is stopped
meanwhile it is transforming caps. The problem is that stop() calls
gst_vaapi_plugin_base_close(), which nullifies the element's va display, but
the va display is used in tranform_caps() when it is extracting the possible
format conversions. This display disappearing generates warning messages.
This patch holds a local reference of va display at ensure_allowed_raw_caps()
hence it doesn't go away meanwhile it is used, even if the
gst_vaapi_plugin_base_close() is called in other thread.

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.
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.
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.

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.

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.

Move some of the logic in gst_vaapi_plugin_base_driver_is_whitelisted() to a
new function gst_vaapi_driver_is_whitelisted(), in this way, it can be used
when registering the plugin's feature set with the test VA display.

if gst_buffer_pool_set_config returns FALSE, check the modified
config and retry set_config if the config is still acceptable.

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
it is used in pluginbase. Hence, the internal enum was moved to
vaapivideobufferpool header.
https://bugzilla.gnome.org/show_bug.cgi?id=765435
This patch refactors the code in pluginbase in order to centralize the buffer
pool instantiation. As the buffer pool config may have different options, these
are gathered using a bitwise flag.
https://bugzilla.gnome.org/show_bug.cgi?id=765435
Originally vaapivideobufferpool instantiates its own allocator regardless the
received configuration, and it relies in custom configuration options to
choose which kind of allocator instantiate.
This patch transfers the responsibility of the allocator instantiate to
vaapipluginbase and pass it to the vaapivideobufferpool through its
configuration.
* gst/vaapi/gstvaapipluginbase.c
+ set_dmabuf_allocator(): inserts a dmabuf allocator in the bufferpool
+ ensure_sinkpad_buffer_pool(): set a normal vaapi video allocator in
bufferpool configuration
+ gst_vaapi_plugin_base_propose_allocation(): call set_dmabuf_allocator() if
needed.
+ gst_vaapi_plugin_base_decide_allocation(): set a normal vaapi video
allocator in bufferpool configuration
* gst/vaapi/gstvaapivideobufferpool.c
+ gst_vaapi_video_buffer_pool_set_config(): instead of instantiate the
allocator, process the received one through its configuration.
* gst/vaapi/gstvaapivideobufferpool.h: removed
GST_BUFFER_POOL_OPTION_DMABUF_MEMORY since it is not used anymore.
* gst/vaapi/gstvaapivideomemory.c
+ gst_vaapi_is_dmabuf_allocator(): new helper function to identify a dmabuf
allocator with the vaapi qdata.

This is a helper function to improve the readability of
ensure_sinkpad_buffer_pool(). It makes clearer when the buffer pool needs to be
re-instantiated.
This buffer pool may still be processing buffers when a caps renegotiation is
done. This one-liner patch deactivates the pool to drain it before it
de-allocation.
Right now, the decoders create a buffer pool for their sink pad which is not
used at all, because the decoders have never proposed it to upstream.
This patch avoids the buffer pool instantiating when the element inherits from
the GstVideoDecoder class.
This patch is a bit of optimization, since the bufferpool configuration is get
when the pool is created. Hence, we only need to request it when the pool from
the allocation query is reused.
If the offered pool in decide_allocation() vmethod doesn't have the
VAAPI_VIDEO_META option, it is destroyed immediatly and the pointer cleared,
so it could be created later.
