* `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.
2010-03-16 13:58:43 +00:00
* `vaapiconvert' is used to convert from video/x-raw-yuv pixels to
2010-03-30 13:17:12 +00:00
video/x-vaapi-surface surfaces.
2010-03-16 13:58:43 +00:00
* `vaapisink' is used to display video/x-vaapi-surface surfaces to
screen.

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
