Hi all,
a few quick questions about loop markers and such (AudioFileMarker):
what is the SMPTE time code field for? The position of the marker is
already specified in frames in mFramePosition isn't it? Is this some
kind of offset - ie. the marker position is at mFramePosition and that
position represents mSMPTETime into the file? How should a program
handle mSMPTETime's that don't agree with the marker positions if
there are more than one marker in the file? More generally, is there
any documentation on the various kCAFMarkerType's and when to use
them? Specifically, what is the difference between ProgramStart and
TrackStart, what kind of marker is kCAFMarkerType_Index, and what do
EditDestination and EditSource mean exactly?
Sorry but I couldn't find any information on these questions and I'd
like to do the right things in my program...
Thanks,
Tahome
