Gallium3D VDPAU On Radeon Starts Working

[yotambien]

VDPAU/XvMC gallium 3d acceleration is also supported on r300 hardware now (commit).

Wait, what? What does this buy us r300 users? Has somebody tested it?

Yes. See http://phoronix.com/forums/showthrea...634#post211634

EDIT: also note that r300 hardware means R300->R500.

But...this is awesome...

But this is basically MC using the VDPAU interface, right? Most of the difficult parts of H264 are still not implemented, AFAIK.

Still very important, but not quite a fully accelerated shader solution just yet.

It currently implements iDCT and MC on the shaders.

Cool, so it's missing VLC and deblocking to support everything VDPAU offers, basically.

All of this is for Mpeg2 only atm, right?

Well, here VPDAU does work with my r300, meaning that it displays video. I too would like to know what streams is meant to accelerate. I'm on the move and I only have available a couple of youtube h264 videos. Using VDPAU with mplayer appears just slightly slower than xv. It will be very nice if it improves somehow. One negative thing is that in fullscreen it scales the video without respecting the aspect ratio...

z-scan, quantification and mismatch control is also implemented and working (at least with r600g).

For r300g I have an old RV350 for testing and got z-scan, quantification, the first idct stage, mc and yuv->rgb/scaling working.
I still have problems with the second idct stage and mismatch control, those shaders uses to many alu/tex instructions.

Also the missing hardware features (instanced drawing, blender clamping control) is giving me quite an headache.

Thanks for the update. You're doing great work!

There is a patch for draw_instanced on Marek branch:

Dunno about its state.
