hi,

Playing anything h264 encoded, at least 1080p, results in atop 67% average cpu usage, even with playing with -lavdopts threads=N. I recall with a geforce 8600 mplayer plays at average of 3% cpu usage.

Is there a way to play h264 with gfx accel on open radeon?

thanks

No. Only mpeg2, and even that using shaders, which is very inefficient. If you want decoding using the dedicated hardware decoders, you'll need to use to proprietary fglrx driver.

Wait a minute, ATI proprietary fglrx driver can do H.264 hardware decoding? Is there any player that supports this?

If xvba-video still works, you can use vaapi players (VLC, mplayer-vaapi). Otherwise, XBMC has direct xvba support in a branch.
