I think I've resolved the hang/green video corruption under xvmc decode of 1080i mpeg2 content with the AppleTV. enable Coolbit is xorg.config then; nvidia-settings -a GPUOverclockingState=1 nvidia-settings -a GPU2DClockFreqs=200,800 This underclocks the gpu and overclocks the vram for 2D which is what xvmc uses. Glitches are gone for both mplayer and myth (both of which use ffmpeg). I've had mplayer running for over 12 hours continuous doing xvmc 1080i mpeg2 decode and it's still going strong. Underclocking the gpu from 360MHz to 200MHz is primary. I've overclocked the vram from 720MHz to 800MHz as xvmc decode seems more sensitive to this parameter. I don't notice any differences in decode performance by underclocking the gpu. Scott |
