690G OpenGL video playback is Green & Purple

[agd5f]

Connection is via LVDS, I can try VGA but will have to wait til after the weekend.

The output doesn't matter.

The 'application' is the python libavg framework. Renders everything using openGL sorry I'm not sure on the specific details of how it all works sorry.
using ffplay works fine I've tested two videos one is mpeg2 the other is an mpeg4 of some variation. I'll check exactly what codecs when I'm near that machine again.

If ffplay uses Xv and it works, I'm guessing it's a problem with the GL code in libavg or the r300 3D driver.

YUV decoding problem.

Sounds like a problem in the colorspace conversion. Does it happen with all videos or just certain ones?

...wait what do you mean by "video playback from within an OpenGL application"? Are you using Xv or is GL rendering the video?

Is this video playback over a normal monitor (VGA, DVI etc..) or over a TVOut (composite, S-Video, component) ?

Hi All,
Finally I have my 690G based computers up and running with open source drivers and everything is running well. Except video playback from within an OpenGL application. Everything is Green and Purple..
System is Ubuntu 8.10 alpha 5 using the radeon driver

Using the radeonhd driver the video playback is the correct colours however the performance is so terrible (about 1/10 of radeon) that it's unusable.

Anyone run into this before or have any suggestions as to how to fix it?
