I need to read an asset from a users iPod library and convert it to LPCM. I
want put up an import progress bar. Any idea how I can find the number of
bytes I need to read? PMediaItemPropertyPlaybackDuration returns the play
back duration in sec.
AVAssetReader *assetReader = [[AVAssetReader
assetReaderWithAsset:songAsset
error:&assetError]
retain];
AVAssetReaderOutput *assetReaderOutput = [[AVAssetReaderAudioMixOutput
assetReaderAudioMixOutputWithAudioTracks:songAsset.tracks
audioSettings: nil]
retain];
if (! [assetReader canAddOutput: assetReaderOutput]) {
return;
}
[assetReader addOutput: assetReaderOutput];
fileSize = [assetReader ????]
Thanks in advance
Andy
