[Openchrome-users] Anyone working on mpeg4, if so, I'd be happy to play 'tester'...

Hi, Chad.

It's not impossible that we can pursuade VIA to release some mpeg4 info, 
at least under NDA, but the problem is there is a lack of time among the 
developers here and also other things that might have higher priority.

When Ivor did an initial test of VIA's mpeg4 accelerated players they 
were slower playing mpeg4 than openChrome's unaccelerated players. 
Nobody has since given us hard figures showing the benefit of 
accelerated mpeg4. AFAICT the current status is that openChrome has the 
fastest mpeg4 playback you can get on VIA cpus. (Bold statement ;)).

If you have some time over to do a test with VIA's driver it would be 
really nice getting some CPU-usage figures both for HD and SD mpeg4 
compared to openChrome's. If it turns out that accelerated mpeg4 really 
makes a difference, it might jump on the priority list.

Thomas
