|
* `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.

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
