* `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4, H.264, VC-1,
|
|
|
|
|
WMV3 videos to video/x-vaapi-surfaces surfaces, depending on the
|
2010-05-04 08:59:27 +00:00
|
|
|
underlying HW capabilities.
|
|
|
|
|
|

|
|
|
* `vaapiupload' is used to convert from video/x-raw-yuv pixels to
|
2010-03-30 13:17:12 +00:00
|
|
|
video/x-vaapi-surface surfaces.

VA elements are automatically plugged into GStreamer pipelines. So,
|
2013-11-22 05:45:22 +00:00
|
|
|
using playbin (or playbin2 with GStreamer 0.10) should work as is.
|
|
|
|
|
However, here are a few alternate pipelines that could be manually
|
|
|
|
|
constructed.
