[Ffmpeg-devel] question: wmv3 codec image "drifts"

Hi--

So I'm working on some mms streaming stuff.

When I stream a file from an asx file, that's not live (but streamed  
via mms), it looks great.

When I play a live stream that's been encoded by the WM9 encoder,  
there is a weird "drift" effect.  The I frames look great, and then  
after that, the changes seem to drift.  The colors then get out of  
whack slowly until the next I frame.

Has anyone seen this before (in a non-streaming solution?)?  I know  
I'm out on the bleeding edge with this, but thought someone might  
have an idea.  Are there known limitations to the wmv3 decoder  
(options that I can disable on the encoder side?)

I don't really know enough about the codec to intelligently figure  
out what it's doing.

Thanks,
-Ryan
