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
-----
* 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
