Hello.
I'm trying to retrieve information what video codec is used for a
video clip in Final Cut Pro XML project file.
When a sequence is exported, the XML contains codec information for
the sequence, but when an individual clip is exported, it doesn't
export the codec information.
However, the FCP somehow figure out what code is used for the clip.
So, what I guess is that it knows by looking at the actual video clip
file.
I could get human readable codec information by using :
NSArray *tracksArray = [movie tracks];
int i, tracks = [tracksArray count];
for( i = 0 ; < tracks; i++ )
{
QTTrack *track [tracksArray objectAtIndex:i];
NSDictionary *attribute = [track tackAttributes]
NSString *codecString = [attribue
objectForKey:QTTrackFormatSummaryAttribute];
....
However, to figure out what fourCC the human readable codec info is
meant for, I need to export clips as all types the QT supports.
So, I would like to retrieve fourCC code directly.
Is there any way to do it? I looked up the reference, but had no luck
so far.
Thank you.
