Through "gst.vaapi.app.Display" context, users can set their own
VADisplay and native display of their backend.
So far we support only X11 display, from now we also support Wayland
display.
Attributes:
- wl-display : pointer of struct wl_display .

Instead to look for the best profile in the allowed profiles by
downstream, the encoder should look for the base profile in the
available profile in VA-API.

Instead of copying the metada in prepare_output_buffer() vmethod,
it is done in append_output_buffer_metadata() thus deinterlaced
buffers could also have the proper metas.
GstVideoCropMeta now it is copied internally and it is decided via
transform_meta() vmethod.
A new internal method, copy_metadata() was added to handle VPP
transformation where non-GstVideoVaapiMeta metas were lost.
When importing buffers to a VA-base buffer, it is required to copy
the metas in the original buffer, otherwise information will be
lost, such as GstVideoRegionOfInterestMeta.

Generate system allocated output buffers when downstream doesn't
support GstVideoMeta.
The VA buffer content is copied to the new output buffer, and it
replaces the VA buffer.
https://bugzilla.gnome.org/show_bug.cgi?id=785054
When downstream can't handle GstVideoMeta it is required to send
system allocated buffers.
The system allocated buffers are produced in prepare_output_buffer()
vmethod if downstream can't handl GstVideoMeta.
At transform() vmethod if the buffer is a system allocated buffer,
a VA buffer is instanciated and replaces the out buffer. Later
the VA buffer is copied to the system allocate buffer and it
replaces the output buffer.

This patch add the member copy_output_frame and set it TRUE when
when downstream didn't request GstVideoMeta API, the caps are raw
and the internal allocator is the VA-API one.
https://bugzilla.gnome.org/show_bug.cgi?id=785054
This function will inform the element if it shall copy the generated
buffer by the pool to a system allocated buffer before pushing it
to downstream.

VA-API based buffer might need a video meta because of different
strides. But when donwstream doesn't support video meta we need to
force the usage of video meta.
Before we changed the buffer pool configuration, but actually this
is a hack and we cannot rely on that for downstream.
This patch add a check fo raw video caps and allocator is VA-API,
then the option is enabled without changing the pool configuration.
In this case the element is responsible to copy the frame to a
simple buffer with the expected strides.

vaapsink, when used with the Intel VA-API driver, tries to display
surfaces with format NV12, which are handled correctly by
Weston. Nonetheless, COGL cannot display YUV surfaces, making fail
pipelines on mutter.
This shall be solved either by COGL or by making the driver to paint
RGB surfaces. In the meanwhile, let's just demote vaapisink as
marginal when the Wayland environment is detected, no matter if it is
Weston.

In propose_allocation() if the numer of allocation params is zero, the
system's allocator is added first, and lastly the native VA-API
allocator.
In decide_allocation(), the allocations params in query are travered,
looking for a native VA-API allocator. If it is found, it is reused as
src pad allocator. Otherwise, a new allocator is instantiated and
appended in the query.
https://bugzilla.gnome.org/show_bug.cgi?id=789476
GST_VAAPI_VIDEO_ALLOCATOR_NAME was added in commit 5b11b8332 but it
was never used, since the native VA-API allocator name has been
GST_VAAPI_VIDEO_MEMORY_NAME.
This patch removes GST_VAAPI_VIDEO_ALLOCATOR_NAME macro.

Don't subscribe to button press events when using a foreing window,
because the user created window would trap those events, preveting the
show of frames.

Check for display's color-balance properties, available by the VA-API
driver, before setting them.
Also logs an info message of those unavailable properties.

gst_vaapipostproc_ensure_filter might free the allowed_srcpad_caps
and allowed_sinkpad_caps. This can race with copying these caps in
gst_vaapipostproc_transform_caps and lead to segfaults.
The gst_vaapipostproc_transform_caps function already locks
postproc_lock before copying the caps. Make sure that calls to
gst_vaapipostproc_ensure_filter also acquire this lock.

gst.vaapi.app.Display context is made for applications that will
provide the VA display and the native display to used by the
pipeline, when are using vaapisink as overlay. There are no use
case for encoders, decoders, neither for the postprocessor.
In the case of the vaapisink, it shall query for gst.vaapi.Display
upstream first, and then, if there is no reply,
gst.vaapi.app.Display context will be posted in the bus for the
application. If the application replies, a GstVaapiDisplay object
is instantiated given the context info, otherwise a
GstVaapiDisplay is created with the normal algorithm to guess the
graphics platform. Either way, the instantiated GstVaapiDisplay
is propagated among the pipeline and the have-message bus message.
Also only vaapisink will process the gst.vaapi.app.Display, if
and only if, it doesn't have a display already set. This is
caused because if vaapisink is in a bin (playsink, for example)
the need-context is posted twice, leading to an error state.

As buffers negotiated with memory:VASurface caps feature can also be
mapped, they can also be configured to use VA derived images, in other
words "direct rendering".
Also, because of the changes in dmabuf allocator as default allocator,
the code for configuring the direct rendering was not clear.
This patch cleans up the code and enables direct rendering when the
environment variable GST_VAAPI_ENABLE_DIRECT_RENDERING is defined,
even then the memory:VASurface cap feature is negotiated.

Set if source pad can handle dmabuf only if the GstGL context comes
from downstream.
It is possible to know that at two moments:
1\ In the case of GstGLTextureUpload caps feature is negotiated and
downstream pool reports back gst.gl.GstGLContext.
2\ When GstGLContext is found as GstContext from dowstream.
https://bugzilla.gnome.org/show_bug.cgi?id=788503
In function gst_vaapi_find_gl_context() add a direction parameter to
return back the direction where the GstGL context was found.
This is going to be useful when checking if downstream can import
dmabuf-based buffers.
https://bugzilla.gnome.org/show_bug.cgi?id=788503
This patch refactors the code by adding the function
vaapi_plugin_base_set_srcpad_can_dmabuf(), it determines if the passed
GstGLContext can handle dmabuf-based buffers.
The function is exposed publicly since it is intended to be used later
at GstVaapiDisplay instantiation.

Tis patch, allows some properties that we want to be set on
runtime. (eg. bitrate)
Note that all properties are under control by num_codedbuf_queued.

VPP support is only needed for advanced deinterlacing, which is not
enabled by default either. Error out if it is selected but VPP is not
supported, and otherwise just work without VPP support.
https://bugzilla.gnome.org/show_bug.cgi?id=788758
When creating the test display for querying capabilites, it try in
certain order: DRM, Wayland and finally X11. GLX nor EGL are tried
since they are either composited with X11 or Wayland.
The reason for this is to reduce the posibility of failure that could
blacklist the plugin.
https://bugzilla.gnome.org/show_bug.cgi?id=782212
We returned FALSE from ::start() if VPP support is not available, but it
is only really needed for complex filters and during transform we check
for that. For simple deinterlacing it is not needed.
Instead of reusing a parameter variable for the return value of
gst_vaapipostproc_transform_caps(), this patch uses the function
scoped pointer. Thus, the code is cleaner.
