Hi all,
I'm playing around a bit with AVFoundation and it seems to have all the audio related functionality I could possibly want (playback, metadata, mixing, etc.) but there's one thing I'm having trouble figuring out. I know how to read metadata from a file via AVAsset's -commonMetadata method, but there doesn't seen to be a convenient way to *change* the metadata of an existing file. The AVMutableMetadataItem class exists, but the only place I can really find where using it would be applicable is AVAssetWriter's metadata property. The overview of AVAssetWriter mentions that it is used for "write media data to a new file", which isn't exactly what I'm looking for.
Any suggestions are appreciated.
Thanks,
Indragie_______________________________________________
