'Twas brillig, and Murray Blakeman at 03/12/08 10:25 did gyre and gimble:
> I use Totem/GStreamer for viewing movie files.
> With Compiz active the picture breaks up, especially in fullscreen.
> How do I improve/fix the performance of video in Compiz.
> CPU usage doesn't go beyond 20% but the picture still breaks up (tears)
> quite often.
> When I disable Compiz I can view the movies perfectly.
> I have enabled the "Video Plugin" for Compiz but it doesn't appear to
> make a difference.
> I've seen patches for mplayer to take advantage of the "Video Plugin"
> but my preference is to continue to use GStreamer if I can.
AFAIK the video plugin defines a kind of experimental extension to XV.
The mplayer patch is the only one to take advantage of this.
I think you'd have to look at what this patch does and then port that
code to gstreamer.
I think the intention was to be a bit more "standard" about the
extension to XV so that wider adoption by other players (gstreamer, xine
etc.) is promoted. You'd be better asking on the compiz mailing list
about this tho'.
There is also nvidias VDPAU "standard" that is in beta now... no idea
what that means for compositing tho', nor how far outside of nvidia
chipsets it could spread.
