Sreerenj Balachandran 38d84d968e plugins: initial port to GStreamer 1.0.
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.

gstreamer-vaapi helper libraries and plugin elements are available
under the terms of the GNU Lesser General Public License v2.1+

Overview
--------

gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries.

  * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4, H.264, VC-1,
    WMV3 videos to video/x-vaapi-surfaces surfaces, depending on the
    underlying HW capabilities.

  * `vaapiupload' is used to convert from video/x-raw-yuv pixels to
    video/x-vaapi-surface surfaces.

  * `vaapidownload' is used to convert from video/x-vaapi-surface
    surfaces to video/x-raw-yuv pixels.

  * `vaapipostproc' is used to postprocess video/x-vaapi-surface
    surfaces, for e.g. deinterlacing.

  * `vaapisink' is used to display video/x-vaapi-surface surfaces to
    screen.


Features
--------

  * VA-API support from 0.29 to 0.32
  * JPEG, MPEG-2, MPEG-4, H.264 and VC-1 ad-hoc decoders
  * OpenGL rendering through VA/GLX or GLX texture-from-pixmap + FBO
  * Support for the Wayland display server
  * Support for headless decode pipelines with VA/DRM
  * Support for major HW video decoding solutions on Linux (AMD, Intel, NVIDIA)


Requirements
------------

Software requirements

  * GStreamer 0.10.x:
      libglib2.0-dev (>= 2.28)
      libgstreamer0.10-dev (>= 0.10.36)
        or with GstBaseSink::query()
      libgstreamer-plugins-base0.10-dev (>= 0.10.36)
      libgstreamer-plugins-bad0.10-dev (>= 0.10.22.1)
        or with GstVideoContext, GstSurfaceBuffer, codecparsers

  * Renderers:
      DRM: libva-dev (>= 1.1.0), libdrm-dev, libudev-dev
      X11: libva-dev (>= 1.0.1)
      GLX: libva-dev (>= 1.0.3)
      Wayland: libva-dev (>= 1.1.0), libwayland-dev (>= 0.95.0)

Hardware requirements

  * AMD platforms with UVD2 (XvBA supported)
  * Intel Eaglelake (G45)
  * Intel Ironlake, Sandy Bridge and Ivy Bridge (HD Graphics)
  * Intel Poulsbo (US15W)
  * Intel Medfield or Cedar Trail
  * NVIDIA platforms with PureVideo (VDPAU supported)


Usage
-----

  VA elements are automatically plugged into GStreamer pipelines. So,
  using playbin2 should work as is. However, here are a few alternate
  pipelines constructed manually.

  * Play an H.264 video with an MP4 container in fullscreen mode
  $ gst-launch-0.10 -v filesrc location=/path/to/video.mp4 ! \
      qtdemux ! vaapidecode ! vaapisink fullscreen=true

  * Play a raw MPEG-2 interlaced stream
  $ gst-launch-0.10 -v filesrc location=/path/to/mpeg2.bits ! \
      mpegvideoparse ! vaapidecode ! vaapipostproc ! vaapisink
