* `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.

|
|
|
|
|
$ gst-launch-0.10 -v filesrc location=/path/to/video.mp4 ! \
|
|

Caveats
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
* No ad-hoc parser, vaapidecoder currently relies on FFmpeg
