Javier Jardón ba3ae60613 plugins: declare _get_type() functions as const. 
Declaring a function as const enables better optimization of calls to
the function.

License
-------

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 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
  * 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 major HW video decoding solutions on Linux (AMD, Intel, NVIDIA)


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

Software requirements

  * libva-dev >= 1.0.3 (VA/GLX)
  * libgstreamer0.10-dev >= 0.10.35.1
      or with GstBaseSink::query()
  * libgstreamer-plugins-base0.10-dev >= 0.10.35
  * libgstreamer-plugins-bad0.10-dev >= 0.10.22.1
      or with GstVideoContext, GstSurfaceBuffer, codecparsers

  If codecparsers-based decoders are not used:

  * libavcodec-dev >= 0.6
      or with <libavcodec/vaapi.h>

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
