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.
Add initial API for video encoding: only basic interfaces and small
encoder objects are implemented so far.

GstBitWriter provides a bit writer that can write any number of bits
to a pre-allocated memory buffer. Helper functions are also provided
to write any number of bits from 8, 16, 32 and 64 bit variables.

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.

Fix detection of VA/JPEG decoding API with non-standard libva packages.
More precisely, some packages were shipping with a <va/va.h> header that
did not include <va/va_dec_jpeg.h>.

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.
