!7It is possible to reduce it if you code your own playback application with QT.
!7Fixed shortdelay = 1<<16;
!7QTSPresSetInfo(myPres,kQTSAllStreams,kQTSTargetBufferDuration,&shortdelay);
As kevin has said,this code can reduce the playback buffer time.But I don't know how to get the parameter myPres,I use code as follows:
ComponentResult c;
QTSMediaPresentationParams myPres;
c = QTSMediaGetIndStreamInfo(theMediaHandler, 1,kQTSMediaPresentationInfo,
&myPres);
Fixed shortdelay = 1<<16;
OSErr theErr = QTSPresSetInfo (myPres.presentationID,
kQTSAllStreams,
kQTSTargetBufferDurationInfo,
&shortdelay );
But the return value of QTSPresSetInfo is -50.I don't know the reson.Can anyone help me?
