Compiz Video Performance
Locked
 
|
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. I have a P4 3.3Ghz, 1GB RAM, with a GeForce FX Go5200 Video. I'm running OpenSolaris 2008.11 with the legacy NVidia drivers. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

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.

Having a composite manager enabled will break the vsync normally provided for Xv as the video gets rendered to an offscreen buffer, and it's the composite manager's job to actually display it. You might want to check if you can reduce tearing by enabling sync-to-vblank (ensuring that it has detected the correct refresh rate) in Compiz' settings. > > 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.

Given that this is the third such standard - Intel introduced one about 1.5 years ago, ATI introduced one a couple of fglrx releases ago - I wouldn't hold my breath. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

Regarding VDPAU, MythTV has already implemented it and it's apparently working very nicely in that program. Seeing as it creates the output path, I'd imagine that it would deal with whatever causes sync-to-vblank issues itself. For the original poster, I would hasten to say that this could not be fixed in gstreamer. The update to DRI2 will apparently make it a lot easier for sync- -to-vblank to work on a composited desktop (though having proprietary drivers implement it is the vendor's call). Is there an updated NVidia driver you can use? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |
