I have uploaded some experimental plugins with VA-API support:

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.

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

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


   * Fully Open Source solution
   * VA-API support from 0.29 to 0.31
   * OpenGL rendering through VA/GLX or GLX texture-from-pixmap + FBO
   * Support for major HW video decoding solutions on Linux (AMD, Intel, NVIDIA)


Software requirements

   * libgstreamer0.10-dev >= 0.10.0
   * libgstreamer-plugins-base0.10-dev >= 0.10.0
   * libva-dev >= 0.31.0-1+sds9 (VA/GLX)
   * libavcodec-dev >= 0.6 or with <libavcodec/vaapi.h>

Hardware requirements

   * AMD platforms with UVD2 (XvBA supported)
   * Intel Eaglelake (G45)
   * Intel Ironlake (HD Graphics)
   * Intel Poulsbo (US15W)
   * NVIDIA platforms with PureVideo (VDPAU supported)


   * No integration within decodebin2 or the playbin2 pipeline
   * No ad-hoc parser, vaapidecoder currently relies on FFmpeg
   * MPEG-4 Part-2 (DivX) has decoding bugs
