Hi guys,
just wanted to give a little status update for the xvmc state tracker
for r600 hardware. I think I found most of the bugs related to
progressive video playback and it now seems to work 100%.
All the old compliance progressive streams (ones ending 015.m2v, 015

Testing interlaced on 600g, I notice that (like most -vo) chroma is
getting treated as progressive when displayed as weaved, so the teeth
may look twice as bad on saturated colours.
Maybe this is already on your radar, just

Review:
A call to radeon_prepare_render() at the beginning of draw
operations was placed too deep in the call chain,
inside r300RunRenderPrimitive(), instead of
r300DrawPrims() where it belongs. This leads to
emission of stale target color renderbuffer into the cs if
bufferswaps via page-flipping are
Alex Deucher is currently preparing patches for page-flipped
bufferswaps on radeon hardware. Testing these on a RV530 gpu
with the R300 classic driver exposed a bug - We call
radeon_prepare_render() too late. This causes massive
visual corruption and eventually graphics hangs.
The following patch
