Currently the H264 and H265 parsers look for MVC and SPS respectively, and
the required symbols for those were added in GStreamer 1.5
If we try to compile in GStreamer < 1.4, without enabling the builtin codec
parsers, the compilation fails, because the lack of those symbols.
This patch verifies if the installed H264 and H265 parsers have those symbols. If
they do not, the specific built in codec parsers are enabled and used.

wl_display_dispatch_queue() might prevent the pipeline from shutting
down. This can happen e.g. if the wayland compositor exits while the
pipeline is running.
This patch replaces it with these steps:
- With wl_display_prepare_read() all threads announce their intention
to read.
- wl_display_read_events() is thread save. On threads reads, the other
wait for it to finish.
- With wl_display_dispatch_queue_pending() each thread dispatches its
own events.
wl_display_dispatch_queue_pending() was defined since wayland 1.0.2

The VA/GLX interfaces are obsolete. They used to exist for XvBA, and
ease of use, but they had other caveats to deal with. It's now better
to move on to legacy mode, whereby VA/GLX interop is two be provided
through (i) X11 Pixmap, and (ii) other modern means of buffer sharing.

Fix arguments to XkbKeycodeToKeysym() for converting an X11 keycode
to a KeySym. In particular, there is no such Window argument. Also
make sure to check for, and use, the correct <X11/XKBlib.h> header
where that new function is defined. Otherwise, default to the older
XKeycodeToKeysym() function.
Supporting anything thing below GStreamer 1.2 is asking for trouble
for keeping up with the required facilities to make efficient pipelines.
Users are invited to upgrade to the very latest GStreamer 1.2.x release,
at the minimum.
Support for GStreamer 0.10 is obsolete. i.e. it is no longer supported
and may actually be removed altogether for a future release. There is
no real point to maintain a build for such an ancient GStreamer version
that is not even supported upstream.
The built-in video parsers elements are built into a single DSO named
libgstvaapi_parse.so. The various video parsers could be accessed as
vaapiparse_CODEC.
For now, this only includes a modified version of h264parse so that to
support H.264 MVC encoded streams.
The built-in libvpx serves multiple purposes, among which the most
important ones could be: track the most up-to-date, and optimized,
range decoder; allow for future hybrid implementations (non-VLD);
and have a completely independent range decoder implementation.
Add libvpx submodule that tracks the upstream version 1.3.0. This is
needed to build a libgstcodecparsers_vpx.so library with all symbols
placed into the GSTREAMER namespace.
It turns out it is more convenient to have only pkgconfig files named
after the installed GStreamer API version (1.0) instead of using all
possible subsequent names from that (1.0, 1.2, 1.4). i.e. they conflict
altogether anyway, so align pkgconfig file names to that.
Bump the library major version due to API/ABI changes that occurred in
the imaging API. In particular, GstVaapiDisplay interfaces no longer
expose any GstCaps but provide GArray based ones e.g. to determine the
set of supported decode/encode profiles.
Fix the pluginsdir and includedir variables in the generated pkgconfig
(.pc) files. The location needs to be built with the PKG version in
mind instead of the API version.
While we are at it, also fix the PKG version for GStreamer >= 1.3.

GStreamer 0.10.36 is the latest and ultimate version to be released
from the GStreamer 0.10 branch. i.e. no further releases are to be
made. So, we can safely enable the built-in videoutils replacement
now that they are in sync with the 0.10 branch.

Automatically detect GStreamer API version. The --with-gstreamer-api
configure option now defaults to "autodetect" and configure then tries
to derive the GStreamer API version from the highest version based on
what pkg-config --modversion would report.

The GStreamer 1.2.x packages sticked to the naming convention for 1.0.x
packages, i.e. -1.0 suffix. However, for gstreamer-vaapi packaging
purposes, update the versioning to -1.2 suffix instead.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.2. This
is rather minimalistic so that to test the basic functionality.
Disable vaapipostproc plugin for now as further polishing is needed.
Also disable GstVideoContext interface support since this API is now
gone in 1.2.x. This is preparatory work for GstContext support.

Use hardware accelerated XRenderComposite() function, from the RENDER
extension, to blit a pixmap to screen. Besides, this can also support
cropping and scaling.
Bump the library major version due to API/ABI changes that occurred in
the imaging API. In particular, GstVaapiImageFormat type was replaced
with the standard GstVideoFormat type. All dependent APIs were updated
to match this change.
Add flag to have all codecparsers built-in, thus ensuring that the
resulting binaries have all the necessary bug fixes and this is what
the QA has been testing anyway.
Of course, for a completely up-to-date Linux distribution, you could
also opt for --disable-builtin-codecparsers and use the system ones.
Though, some core fixes could be missing, and those cannot be tested
for with API checks.
The whole libgstvaapi libraries got a major refresh to get rid of GObject.
This is a fundamental change that requires a new SONAME. More changes are
underway to streamline the core libraries.
So far, the net result is a reduction of .text size (code) by 32KB, i.e. -10%.
On one particular test (sintel HD trailer), the total number of executed
instruction was reduced by 8%.
Ensure libgstvaapi-glx*.so builds against libdl since dlsym() is used
to resolve glXGetProcAddress() from GLX libraries. This fix builds on
Fedora 17.

Bump library major version, while preserving a major version of 0 for
GStreamer 1.0 based libraries, and a major version of 2 for GStreamer
0.10 based librarieS.
Introduce a new configure option --with-gstreamer-api that determines
the desired GStreamer API to use. By default, GStreamer 1.0 is selected.
Also integrate more compatibility glue into gstcompat.h and plugins.
This integrates support for GStreamer API >= 1.0 only in the libgstvaapi
core decoding library. The changes are kept rather minimal here so that
the library retains as little dependency as possible on core GStreamer
functionality.

vaapisink is now built with support for multiple display types, whenever
they are enabled. The new "display" attribute is used to select a particular
renderer.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
GStreamer -base plugins >= 0.10.31 are now required, so the checks for
new APIs like GstXOverlay::set_window_handle() and ::set_render_rectangle()
are no longer necessary.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
Also do not generate tamplate files as all the documentation is inline.
