Is AVMutableVideoComposition missing the customVideoCompositor property?

Hi,


According to the documentation for the AVVideoCompositing protocol:


"When creating instances of custom video compositors, AV Foundation initializes them by calling init and then makes them available as the value of the customVideoCompositor property of the object to which it was assigned. You then can do any additional setup or configuration to the custom compositor."


AVMutableVideoComposition has a customVideoCompositorClass property, but does not have a customVideoCompositor property.


Am I misunderstanding this? I need to access the instance to set some properties on it, but I cannot.


Thanks,

Frank

Seems the only way to access it is via AVAssetExportSession, AVPlayerItem or AVAssetImageGenerator (maybe some more). Kind of a bummer :(
