I was wondering how to access an MPMediaItem's raw data.
Any ideas?
you can obtain the media item's data in such way:
-(void)mediaItemToData
{
// Implement in your project the media item picker
MPMediaItem *curItem = musicPlayer.nowPlayingItem;
NSURL *url = [curItem valueForProperty: MPMediaItemPropertyAssetURL];
AVURLAsset *songAsset = [AVURLAsset URLAssetWithURL: url options:nil];
AVAssetExportSession *exporter = [[AVAssetExportSession alloc] initWithAsset: songAsset
presetName: AVAssetExportPresetPassthrough];
exporter.outputFileType = @"public.mpeg-4";
NSString *exportFile = [[self myDocumentsDirectory] stringByAppendingPathComponent:
@"exported.mp4"];
NSURL *exportURL = [[NSURL fileURLWithPath:exportFile] retain];
exporter.outputURL = exportURL;
// do the export
// (completion handler block omitted)
[exporter exportAsynchronouslyWithCompletionHandler:
^{
NSData *data = [NSData dataWithContentsOfFile: [[self myDocumentsDirectory]
stringByAppendingPathComponent: @"exported.mp4"]];
// Do with data something
}];
}
This code will work only on ios 4.0 and later
Good luck!
