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
|
|
-----
|
|
|
|
The GStreamer pipeline currently has to be built manually.
|
|
i.e. neither decodebin{,2} nor playbin{,2} would select the VA-API
|
|
elements automatically.
|
|
|
|
* 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
