I'm running myth with separate front/back end computers. The frontend is a 2.8GHz P4 with 512MB ram, trying to display 720p HD, but I'm maxing out the CPU - myth ~65+%, X around 30+%. The video is at times choppy when there's a lot of stuff changing in the frame. What can I do to reduce CPU usage?
Here's what I've done so far: -compiled myth with --enable-proc-opt (using SVN from less than a week ago) -using ratpoison for window manager -not using any deinterlacing Note: XvMC is not an option. I'm running FC4. mythfrontend -v playback reports that it's using Xvideo, format I420, using realtime priority, video timing method: RTC (glx vsync not supported in my driver). Then I get a lot of video ahead of audio dropping frames messages, and then a lot of audio ahead of video messages. /proc/meminfo says there's 100MB free while running myth, so I guess it's not swapping. What might be causing the high CPU? I've read about people with 2.4Ghz P4s not having a problem with HD, so it seems like there should be something I can do. Would compiling my own kernel help? With what options? Anything else I can try first? -Jerry _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
