Hi, I am trying to track down a problem I have with MythTv under Fedora 8 using the openchrome driver and libchromeXvMC library. MythTv has a lot of juddering and glitches even though the XvMC VLD acceleration is in use. This is also present with the stock via driver and libviaXvMC library.
Using the old mp2decoder XvMC test program I see that sending one frame at 25Hz uses about 12% CPU. If I modify mp2decoder to send two frames at 50Hz (Just calling XvMCPutSurface twice with the same frame) the CPU usage shoots up to 98%. This is equivalent to MythTv outputting in BOB de-interlace mode and appears to show the same problem I have with MythTv. I guess this could be a libchromeXvMC/libviaXvMC or DRM issue. Has anyone any idaes on this ?
