Hi everybody, just wanted to note that I got the first implementation of the XvMC iDCT code working. The luma/chroma scaling and clamping still need some work, but beside from that the pure matrix multiplication seems to work fine.
At the moment it uses a quite inefficient two stage approach and on large resolutions mplayer is complaining that my system is to slow to play this (with only around 8% CPU in use). So the bottleneck is no longer the CPU and starts to be the GPU calculation. While working on the iDCT code I found a couple of bugs in the command checker, and also implemented support for signed normalized colour buffers in r600g, but I think I will spam the different mailing list with separate patches about this. Regards, Christian. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
