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"

So far vaapi encoder does not set profile to src caps. This patch makes it
setting profile to src caps, which is determined by itself.
In addition, if encoder chose different profile, which is not negotiated with
downstream, we should set compatible profile to make negotiation working.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
Check if the requested profile in source caps, is supported by the
VA driver. If it is not, an info log message is send saying that
another (compatible?) profile will be used.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
First check if downstream requests ANY caps. If so, byte-stream is
used and the profile will be choose by the encoder. If dowstream
requests EMPTY caps, the negotiation will fail.
Lately, byte-stream and profile are looked in the allowed caps.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
The check for avc stream format was done in the vaapi encoder's
vmethod get_caps(), but that is wrong since it has to be check
when encoder set_format().
https://bugzilla.gnome.org/show_bug.cgi?id=757941
vaapipostproc didn't negotiate the proper multiview caps losing
downstream information.
This patch enables the playing of MVC encoded stream by setting
the proper multiview mode/flags and views to src caps, according
to sink caps.

There is another regression with 7a206923 when setting the video
info for the video meta, it should be the one from the image's
allocator rather from the allocation caps.
Test pipeline:
gst-launch-1.0 filesrc location=bug766184.flv ! decodebin \
! tee ! videoconvert ! videoscale \
! video/x-raw, width=1920, height=1080 ! xvimagesink
There is a regression in 7a206923, since the buffer pool ditches all
the buffers generated by them because the pool config size is
different of the buffer's size.
Test pipeline:
gst-launch-1.0 filesrc location=big_buck_bunny_1080p_h264.mov \
! qtdemux ! vaapih264dec ! vaapipostproc ! xvimagesink \
--gst-debug=GST_PERFORMANCE:5
The allocator may update the buffer size according to the VA surface
properties. In order to do this, the video info is modified when the
allocator is created, which reports through the allocation info the
updated size, and set it to the pool config.
Refactor the set_config() virtual method considering a cleaner
approach to allocator instanciation, if it it not set or if it is
not valid for the pool.
https://bugzilla.gnome.org/show_bug.cgi?id=783599
The vaapi video decoders might have different allocation caps from
the negotiation caps, thus the GstVideoMeta shall use the negotiation
caps, not the allocation caps.
This was done before reusing gst_allocator_get_vaapi_video_info(),
storing there the negotiation caps if they differ from the allocation
ones, but this strategy felt short when the allocator had to be reset
in the vaapi buffer pool, since we need both.
This patch adds gst_allocator_set_vaapi_negotiated_video_info() and
gst_allocator_get_vaapi_negotiated_video_info() to store the
negotiated video info in the allocator, and distinguish it from
the allocation video info.

Renamed local video info structure names in set_config() vitual
method. The purpose of their renaming is to clarify the origin
of those structures, whether come from passed caps parameter
(new_allocation_vinfo) or from the configured allocator
(allocator_vinfo).
https://bugzilla.gnome.org/show_bug.cgi?id=783599
Renamed private GstVideoInfo structure video_info to allocation_vinfo
and alloc_info to negotiated_vinfo.
The purpose of these renaming is to clarify the origin and purpose of
these private variables:
video_info (now allocation_vinfo) comes from the bufferpool
configuration. It describes the physical video resolution to be
allocated by the allocator, which may be different from the
negotiated one.
alloc_info (now vmeta_vinfo) comes from the negotiated caps in
the pipeline. It represents how the frame is going to be mapped
using the video meta.
In Intel's VA-API backend, the allocation_vinfo resolution is
bigger than the negotiated_info.

When state of vaapisink is changed from PLAYING to NULL, the handle_events
flag is set to FALSE, and never recovered, and then event thread is never
going to run.
So we should allow to set the flag only when users try it.
