[MPlayer-G2-dev] Darwin port

[Dan Christiansen]

Just wondering, is it on purpose that the darwin/big endian parts 
aren't in pre21? The pre20 patch applies fine, though, so I'm compiling 
it right now.

I'll do some testing of the accuracy of usleep(), nanosleep() and 
CFRunLoopRunInMode() later today. I'm especially interested in how 
CoreFoundation performs - using a run loop instead of blocking has some 
advantages. Which stresses the timers most? Dropping frames or playing 
smoothly?
