Fix generation of source tarballs when certain conditionals are not
met. e.g. always include all buildable codecparsers sources in the
distribution tarball, fix plug-in element sources set to include X11
and encoder bits.
Introduce a new GstVaapiPluginBase object that will contain all common
data structures and perform all common tasks. First step is to have a
single place to hold VA displays.
While we are at it, also make sure to store and subsequently release
the appropriate debug category for the subclasses.
Add GstVaapiEncodeMPEG2 element object. The actual plug-in element
is called "vaapiencode_mpeg2".
Valid properties:
- rate-control: rate control mode (default: cqp - constant QP)
- bitrate: desired bitrate in kbps (default: auto-calculated)
- key-period: maximal distance between two key frames (default: 30)
- max-bframes: number of B-frames between I and P (default: 2)
- quantizer: constant quantizer (default: 8)

Add GstVaapiEncodeH264 element object. The actual plug-in element
is called "vaapiencode_h264".
Valid properties:
- rate-control: rate control mode (default: none)
- bitrate: desired bitrate in kbps (default: auto-calculated)
- key-period: maximal distance between two key frames (default: 30)
- num-slices: number of slices per frame (default: 1)
- max-bframes: number of B-frames between I and P (default: 0)
- min-qp: minimal quantizer (default: 1)
- init-qp: initial quantizer (default: 26)

Fix build when Wayland headers don't live in plain system include dirs
like /usr/include but rather in /usr/include/wayland for instance.

Port vaapipostproc element to GStreamer 1.2. Support is quite minimal
right now so that to cope with auto-plugging issues/regressions. e.g.
this happens when the correct set of expected caps are being exposed.
This means that, currently, the proposed caps are not fully accurate.
If the allocation meta GST_VIDEO_GL_TEXTURE_UPLOAD_META_API_TYPE is
requested, and more specifically under a GLX configuration, then add
the GstVideoGLTextureUploadMeta to the output buffer.

Add thin compatibility layer for the deprecated GstVideoContext API.
For GStreamer API >= 1.2, this involves the following two functions:
- gst_vaapi_video_context_prepare(): queries if a context is already
set in the pipeline ;
- gst_vaapi_video_context_propagate(): propagates the newly-created
context to the rest of the pipeline.

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.

Install a new video converter that supports X11 pixmap targets for X11
backends only, or make the GLX converter creation function chain up to
the X11 converter whenever requested.
Add support for interlaced streams with GStreamer 1.0 too. Basically,
this enables vaapipostproc, though it is not auto-plugged yet. We also
make sure to reply to CAPS queries, and happily handle CAPS events.
Fix make dist to allow build for either GStreamer 0.10 or 1.0. i.e. make
sure to include all source files in either case while generating source
tarballs.
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.
Add initial support for GstVaapiVideoMemory backed buffer pool. The memory
object currently holds a reference to GstVaapiVideoMeta.

is rather minimalistic so that to test the basic functionality.
Disable vaapiupload, vaapidownload and vaapipostproc plugins. The latter
needs polishing wrt. to GStreamer 1.x functionality and the former are
totally phased out in favor of GstVaapiVideoMemory map/unmap facilities,
which are yet to be implemented.

Move GstVaapiVideoMeta from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there. Also inline reference
counting code from GstVaapiMiniObject.
Make sure libgstvaapi core decoding library doesn't include un-needed
dependencies. So, move out GstVaapiVideoConverterGLX to plugins instead.
Besides, even if the vaapisink element is not used, we are bound to have
a correctly populated GstSurfaceBuffer from vaapidecode.
Also clean-up the file along the way.
Add new GstVaapiUploader helper to upload raw YUV buffers to VA surfaces.
It is up to the caller to negotiate source caps (for images) and output
caps (for surfaces). gst_vaapi_uploader_has_direct_rendering() is available
to help decide between the creation of a GstVaapiVideoBuffer or a regular
GstBuffer on sink pads.

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.
Add vaapipostproc element for video postprocessing. So far, only basic
bob deinterlacing is implemented. Interlaced mode is automatically
detected based on sink caps ("interlaced" field).
This new interface allows for upstream and downstream display sharing
that works in both static and dynamic pipelines.
