gstreamer-vaapi
VA-API support to GStreamer
Copyright (C) 2010 Splitted-Desktop Systems

gstreamer-vaapi helper libraries are available under the terms of the
GNU Lesser General Public License v2.1+.
gstreamer-vaapi plugin elements are available under the terms of the
GNU General Public License v2+.
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.
* `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
screen.
Features
--------
* 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)
Requirements
------------
Software requirements
* libgstreamer0.10-dev >= 0.10.0
* libgstreamer-plugins-base0.10-dev >= 0.10.16
* 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 Poulsbo (US15W)
* Intel Eaglelake (G45)
* Intel Ironlake (HD Graphics)
* NVIDIA platforms with PureVideo (VDPAU supported)
Usage
-----
* 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
Caveats
-------
* No ad-hoc parser, vaapidecoder currently relies on FFmpeg
* MPEG-4 Part-2 (DivX) has decoding bugs
