[SOLVED] Video playback jittery

foxbunny · 2007-10-19 12:11:11

I'm having this issue since one of the updates. I don't know which update because I've done like 3 of them before I finally played a DVD. The video sort of hangs for a brief moment in regular intervals. Sound goes okay, but the picture acts like it's stopping to drop a few frames (fraction of a second).

How would I go about troubleshooting this?

I'm using KDEmod, the OSS ATI drivers, running the latest stable X from extra. No testing packages, the kernel is -ARCH. I have all the codecs and DVD stuff, plus a host of gstreamer codecs installed there just in case I want a GTK player (which I don't atm). I play video from kaffeine. It doesn't really matter what video format I play, they all have this issue, so I think it is X related. Will review the logs when I get home. Meanwhile, if you have any suggestions as to what else I should do...

Did KDEmod update to 3.5.8 yesterday, but the problem persists.

Maybe your xine engine is set to render via opengl ?
Try to set it to xv, maybe that will help ?

Ah, I've totally forgot to check that option. Thanks for the tip. Will try that.

Checked the xine engine options. It was already set to xv. I have never used anything but xv, so I don't know what changing this could do. Some settings don't work.

Grepping Xorg.0.log for EE gives me:

I doubt it will help. The video playback is jittery in EVERY one of the pleayers I have tried. Even the flash player.

Okay, so here's the strangest part. The video playback was not the only thing that was jittery. Everything that needed to show a continuous flow of frames, like glxgears, or full-screen games were choppy. And then I decided to trash .kde for my KDEmod, and everything works fine now... So, yeah, [solved]. Not just that, everything works MUCH faster now.

I'm wondering now, which part of .kde should really have been trashed...

Arch Linux
