It doesn't.  mplayer calls functions in LibSDL which calls functions 
used in the proprietary CoreGraphics WindowServer (aka Quartz)

Additionally mplayer can use either LibSDL or CoreAudio (aka 
NextStepSound) for sound output.

QuickTime is only used to decode proprietary audio and video in the 
same way the WINE DLL loader does under x86 UNIX builds.
