Add a "vaapidecodebin" element to vaapi plugins.
Child Elements: "vaapidecode ! queue ! vaapipostproc"
The Reasons for implementing a new bin element:
-- Help to Autoplug Hardware Accelerated Video Postprocessing element in playbin
with out any dependency to upstream gstreamer.
This is to overcome the *unacceptable* delay in upstream gstreamer to get new
features in. Eg: https://bugzilla.gnome.org/show_bug.cgi?id=687182.
Also customers using older gstreamer versions (1.2 and 1.4) will get the
benefit of autoplugging, hardware accelerated deinterlacing support etc.
-- Help to maintain a single thread implementation in vaapidecode.
This will result a dead-lock free vaapidecode in most of the cases.
More details here: https://bugzilla.gnome.org/show_bug.cgi?id=742605https://bugzilla.gnome.org/show_bug.cgi?id=745216
This is for helping decodebin to autoplug the vaapidecode element.
Decodebin is selecting decoder elements only based on rank and caps.
Without overriding the autoplug-* signals there is no way to autoplug
HW decoders inside decodebin. An easier soulution is to raise the
rank of vaapidecode, so that it gets selected first.

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)

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.
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.

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 the name of the plug-in element reported to gst-inspect-1.0. i.e. we
need an explicit definition for GStreamer >= 1.0 because the GST_PLUGIN_DEFINE
incorrectly uses #name for creating the plug-in name, instead of using macro
expansion (and let further expansion of macros) through e.g. G_STRINGIFY().
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.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.0. This
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.

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).
