Okay, so I did what you said, but yet, it still won't show me the
track names. Here is my code:
Media media = [[[[[movieView movie] tracksOfMediaType:QTMediaTypeText]
objectAtIndex:0] media] quickTimeMedia];
TimeValue64 timeValue = 0;
TimeValue64 duration = 0;
GetMediaNextInterestingDecodeTime(media, nextTimeMediaSample +
nextTimeEdgeOK, timeValue, fixed1, &timeValue, &duration);
ByteCount size;
GetMediaSample2(media, NULL, 0, &size, timeValue, NULL, NULL, NULL,
nil, nil, 1, NULL, NULL);
char chars[size];
GetMediaSample2(media, &chars, size, NULL, timeValue, NULL, NULL,
NULL, nil, nil, 1, NULL, NULL);
NSString *string = [[NSString alloc] initWithBytes:chars length:size
encoding:NSUTF8StringEncoding];
NSLog(@"String: %@", string);
Thanks,
Joe

Hi Joe,
Since you didn't define "easy" or tell me what you'd tried, then
I'll have to make some assumptions about what you know. I will
assume that you have read the documentation on QT media samples.
The basic steps:
Get the text track.
Get the track media.
loop thru the media samples using a function like
GetMediaNextInterestingDecodeTime() with the parameters of your choice
Use GetMediaSample2() to get the data/length associated with the
text sample.
Create an NSString with the bytes/length returned in the previous
call
regards,
douglas

I have a QTMovie (that is valid), and it has a text track. I am
wondering if there is any easy way to get the contents of the text
track into an NSString.
Thanks,
Joe
