Gwenole Beauchesne 6e82da1e93 decoder: delegate surface size check to VA context reset.
Now that the surface pool is reference counted in the surface proxy wrapper,
we can safely ignore surface size checks in gst_vaapi_decoder_ensure_context().
Besides, this check is already performed in gst_vaapi_context_reset_full().

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
