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.

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.

When glimagesink negotiates the caps feature memory:DMABuf the
exported dmabufs buffers with NV12 format are not well rendered, thus
setting only planar.

Instead of using gst_vaapi_display_set_property() or
gst_vaapi_display_get_property(), this patch set replace it usage
with g_object_set() or g_object_get().
Also the internal helper cb_set_value() is removed since it is not
used anymore.

Make sure vaapisink create a va surface backed buffer pool and all
required attributes get assigned correctly for drm display type.
This is needed to make the below pipeline working:
gst-launch-1.0 filesrc location= raw_video.mov ! videoparse format=uyvy
width=320 height=240 framerate=30/1 ! vaapisink display=drm

A new FEI based encoder element for h264 is added: vaapih264feienc
FEI is a an extension to VA-API which is providing low level
advanced control over different stages of encoding.
Extending vaapih264enc with fei support is possible, but it will
make the code too much complicated and will be difficult
to debug. So adding the new encoder element, but keeping
the rank as 0 , vaapih264enc will stay as the primary
encoder for normal use cases.
The vaaih264feienc is mainly useful for customers who want to play
with MotionVectors and Macroblock Predictions. Also user can
do one stage of encoding(eg: only the Motion Vector Calculation)
in software and offload trasformation/entroy-coding etc to
Hardware (which is what PAK module is doing) using FEI element.
vaapih264feienc can work in different modes using fei-mode properoty
eg: gst-launch-1.0 videotestsrc ! vaapih264feienc fei-mode=ENC+PAK ! filesink location=sample.264
Important Note: ENC only mode won't produce any encoded data which is expected.
But ENC alwys requires the output of PAK in order to do the inter-prediction
over reconstructed frames.
Similary PAK mode alway requires MV and MBCode as input, so unless there is an
upstream element providing those buffers, PAK only won't work as expected.
In a nutshell, ENC_PAK and the ENC+PAK modes are the only options we can verify
with vaapih264feienc. But ideally, EN+PAK mode verification is enough to make sure
that ENC and PAK are working as expected since ENC+PAK mode always invoke ENC and PAK
separately in vaapih264feienc.

Instead including particular gstgl header files in a header file
that doesn't export a gstgl symbol, the main gstgl header file is
included in gstvaapipluginutil.c where the symbols are used.

Coverity scan bug:
An unsigned value can never be negative, so this test will always
evaluate the same way.
As len is guint32, there is no need to check it if it is equal or
bigger than zero.
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.
Refactor gst_vaapi_plugin_base_create_gl_context() in order to check
the return value of gst_gl_ensure_element_data(). The result is a code
bit cleaner.
The function g_bit_nth_lsf() may return -1 if the request bit position
is not avaible. Thus, this patch check if the return value is not -1
in order to continue.
Replacing GstVaapiDisplay during rendering might be hiding problems
at some cases, even though it's safe currently since we use cache
of GstVaapidisplay.
Play safe by failing if this happens.

Through "gst.vaapi.app.Display" context, users can set their own VADisplay
and native display of their backend.
Attributes:
- display : pointer of VADisplay
- x11-display : pointer of X11 display (Display *), if they're using.
This patch creates GstVaapidisplayX11 if information provided through
"gst.vaapi.app.Display"
