[QUOTE="Owlsroost, post: 636312, member: 83973"] [b]Re: AW: MP1 EVR Presenter/dshowhelper community development[/b] I didn't intend to totally rework parts of the code - it just worked out that way :) It's good to get some feedback from an ION/Win7 user - especially someone willing to experiment with the code ;) I usually get about 0.02% dropped frames on my system (Vista/E4400/9500GT) - normally due to time stolen by Windows from MP i.e. 10-20ms time lost = dropped frame. As Tourettes said, the dwshowhelper code itself should use very little CPU/CPU time - it's just deciding when things happen. not actually doing the processing itself. You could try playing around with the thread priorities - the base priorities are set in StartWorkers(). In 'Scheduler.cpp' the Timer and Worker threads are under [URL="http://msdn.microsoft.com/en-us/library/ms684247(VS.85).aspx"]Multimedia Class Scheduler Service[/URL] (MMCSS) control - the SchedulerThread isn't (because it seems to have side effects sometimes) but you could try enabling it - just un-comment the code blocks at the beginnng & end of the function. You could also try commenting out: p->pPresenter->NotifyTimer(hnsTargetTime); //Wake up Timer thread and modify 'timDel + 1' to 'timDel' on the next line, so that the TimerThread timer isn't used - it will save a little bit of CPU time. In 'EVRCustomPresenter.h' if you: // uncomment the //Log to enable extra logging #define LOG_DELAYS //Log you'll get info in the log file about high internal latencies and delays which might help to see why the frames are being dropped. Have fun.... Tony [/QUOTE]
