Whatever, this is not a flame war. My point was that ATI is consistently the first company to innovate things and to fail since they're unable to market and use it correctly.

This "In the future there will be robots" kind of news is getting old. By the time XvBA is oficially published there would be a new X.org version and, guess what? It won't be supported by the Catalyst driver so we'll be stuck with the open source drivers.

Intel Poulsbo only supports VA-API, but it seems Intel bought that driver as closed source only it seems and I don't think there will be many updates for it. There exists a VDPAU to VA-API wrapper which was used for benchmarking too on that site and VA-API patches for mplayer. So when the xvba wrapper to VA-API would be released for everybody that should be enough for now.

When will this API/subsystem nightmare end? Please make a unified API for hardware video decoding, this is a pain in the ass...
Xv (Xvideo) is a colorspace conversion and scaling system. It is not really video playback, although it's useful for putting video frames to the screen quickly.
I am completely okay with XvMC, VDPAU, VAAPI, XvBA, and/or any other video decoding frontend in Gallium. Completely. I'm just not doing it right now.

I don't know if it materialized, but this is _really_ the way to go!
