Hi,
I have posted some patches to add VA-API support to clutter-gst:
http://bugzilla.openedhand.com/show_bug.cgi?id=2119
You need gstreamer-vaapi = 0.2.2 available at:
http://www.splitted-desktop.com/~gbeauchesne/gstreamer-vaapi/
Hardware requirements:
* AMD platforms with UVD2 (XvBA supported)
* Intel Eaglelake (G45)
* Intel Ironlake (HD Graphics)
* Intel Poulsbo (US15W)
* NVIDIA platforms with PureVideo (VDPAU supported)
Software requirements:
* Recent enough GStreamer stack
* Probably the Moorestown drivers on US15W
* GLX = 1.3 (GLX texture-from-pixmap) for Ironlake. i.e. this won't work
with Ubuntu 10.04 final, though it probably should with Fedora 13
* Any libVA would suit but it's preferable to use our variant with VA/GLX
extensions because:
- I will only build xvba-video against it
- It provides the most efficient path to avoid texture-from-pixmap
wherever possible. e.g. AMD, and NVIDIA in the future.
I have only tested H.264 decoding on AMD and NVIDIA platforms. Performance
is quite decent (in round 2): 1080p is playable with 20% CPU @ 1 GHz in
powersave mode.
There is still some work to do (in gstreamer-vaapi) but this is working
enough. If someone has HTML5 video working with clutter-mozembed /
clutter-gst, I am all ears. ;-)
Regards,
Gwenole.
