There is a race condition where g_drm_device_type can be left set to
DRM_DEVICE_RENDERNODES when it shouldn't.
If thread 1 comes in and falls into the last else statement setting up both
RENDERNODES and LEGACY types. And begins to process the first type (RENDERNODES),
it sets g_drm_device_type = RENDERNODES.
Now when thread 2 comes in and sees g_drm_device_type is RENDERNODES, it queues
up that type to be tried but then encounters the lock and has to wait until the
first thread finishes. Once the lock is acquired it will then proceed to ONLY try
RENDERNODES and fail it. But it doesn't try LEGACY. And from then on, all future
attempts will only try RENDERNODES.
So to avoid this situation I have simply moved the acquisition of the lock higher
up in the attached patch.

The video pool can be accessed with the display lock held, for example,
when releasing a buffer from inside vaapisink_render, but allocating
a new object can may also take the display lock. Which means a possible
deadlock.

The support for buffer exports in VA-API was added in version 0.36. These
interfaces are for interop with EGL, OpenCL, etc.
GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi
has to support VA-API versions ranging from 0.30.4, which doesn't support it.
This patch guards all the buffer exports handling (and dmabuf allocator) if
the detected VA-API version is below 0.36.

The member size in GstMpeg4Packet is gsize which is unsigned, which cannot be
less than zero. Hence this pre-condition test is a no-op. This patch removes
that code.

slice_type in slice_param is defined as (char *), but it is compared against a
signed integer. clang complains about this comparison.
This patch casts the variable.

The symbol GstVaapiCodedBuffer is already defined in
gst-libs/gst/vaapi/gstvaapicodedbuffer.h which is loaded, at the end, by
gstvaapiencoder_objects.h. Clang complains about the symbol re-definition.
This patch removes that redefinition.

The member value in frame_rate_tab is float, the result of the abs() function
should be float too. But abs() only manages integers.
This patch replaces abs() with fabsf() to handle correctly the possible floats
values.

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

This library was intended to add the base classes for video decoders which
where not included in gstreamer-0.10.
Since the support of gstreamer-0.10 is deprecated those classes are not
required, thus the whole library is removed.

This patch only removes the support of gstreamer-0.10 in the autotools
scripts. No other files are touched.
The configuration parameter --gstreamer-api was deleted since now it is always
auto-detected.
The verification of vmethod query in GstBaseSinkClass was removed since it was
added in gstreamer 0.10.35. The same case for GstVideoOverlayComposition and
its format flags.
The precious variable GST_PLUGIN_PATH was removed, while GST_PLUGIN_PATH_1_0
remained.
The automake files were changed accordingly.
Removed, in debian/control, the vaapiupload and vaapidownload descriptions.

Add support for H.264 MVC Multiview High profile encoding with
more than 2 views. All views within the same accesss unit are
provided in increasing order of view order index (VOIdx).
Upto 10 view are supported for now.
A new property "view-ids" has been provided for the plugins to
set the view ids (which is an array of guint values) to be used
for mvc encoding.

Add support for GstVideoGLTextureOrientation modes. In particular,
add orientation flags to the GstVaapiTexture wrapper and the GLX
implementations. Default mode is that texture memory is laid out
with top lines first, left row first. Flags indicate whether the
X or Y axis need to be inverted.
Add GstVaapiTextureEGL abstraction that can create its own GL texture,
or import a foreign allocated one, while still allowing updates from a
VA surface.
Add helpers to import EGLImage objects into VA surfaces. There are
two operational modes: (i) gst_vaapi_surface_new_from_egl_image(),
which allows for implicit conversion from EGLImage to a VA surface
in native video format, and (ii) gst_vaapi_surface_new_with_egl_image(),
which exactly wraps the source EGLImage, typically in RGBA format
with linear storage.
Note: in case of (i), the EGLImage can be disposed right after the
VA surface creation call, unlike in (ii) where the user shall ensure
that the EGLImage is live until the associated VA surface is no longer
needed.

Add initial support for EGL to libgstvaapi core library. The target
display server and the desired OpenGL API can be programmatically
selected at run-time.
A comprehensive set of EGL utilities are provided to support those
dynamic selection needs, but also most importantly to ensure that
the GL command stream is executed from within a single thread.

Practically we should be able to support more formats, for eg:
JPEG Encoder can support YUV422, RGBA and all.
But this is causing more issues which need proper fix here and there.
Otherwise the condition could become true before the lock
is taken and the g_cond_signal() could be called
before the g_cond_wait(), so the g_cond_wait() is never
awoken.

Add support for GEM buffer imports. This is useful for VA/EGL interop
with legacy Mesa implementations, or when it is desired or required to
support outbound textures for instance.
