Re: Getting Movie Track Format info


On Jun 23, 2006, at 12:03 PM, I wrote:

QTGetTrackProperty([track quickTimeTrack], kQTPropertyClass_Audio,  

kQTAudioPropertyID_SummaryString, size, &str, nil);


That should actually be:

if (QTGetTrackPropertyInfo([track quickTimeTrack],  
kQTPropertyClass_Audio, kQTAudioPropertyID_SummaryString, nil, &size,  
nil) == noErr)
QTGetTrackProperty([track quickTimeTrack], kQTPropertyClass_Audio,  
kQTAudioPropertyID_SummaryString, size, &str, nil);


Sorry for any confusion.
