hi,

Nvidia has had vid accel for ages and did a pretty good job even for geforce 8600. I was stunned to see 20GB h264 file with mplayer using only 3% cpu usage.

But what about open source radeon?? Is such a waste to have a modern card one that can't handle urxvt properly and ZERO video hardware accel (and no, mpeg accel doesn't count, nobody uses it).

Prolly nouveau will get ahead of radeon on this front. Anybody know how long, or what's holding up video hardware accel on radeons??

thnks

Actually the video acceleration code is inside mesa and mostly shared between radeon and nouveau. So it is unlikely that one gets codec support long before the other.

Current video decode acceleration development can be tracked here: http://cgit.freedesktop.org/mesa/mesa/log/src/gallium/auxiliary/vl

Apparently, UVD (Radeon's video decoder) is tightly coupled with stuff required for DRM (that's Digital "Rights" Management, not Direct Rendering Manager). So it's tricky to release open source code interfacing with the UVD without compromising the DRM parts. That's why there's no support yet. So if you want UVD support, use the fglrx driver.
