AVAudioPlayer playing M4P, DRM, Protected AAC

YarGnawh · 07-23-2009, 11:14 AM

iTunes iMix RSS Feed has a URL to a 30 second preview in a protected AAC M4P file.

iTunes iMix - HAIRY LMFAO GAGA

If you browse to the link on Mobile Safari, it plays the 30 second preview in "Quicktime". I'm trying to play the m4p file using AVAudioPlayer, but it gives me an error.

Error Domain=NSOSStatusErrorDomain Code=2003334207 "Operation could not be completed. (OSStatus error 2003334207.)"

Anyone have any insight on this issue?

No one was interested in your post so I hope and guess you figured out the solution for yourself?
Probably you can share this here for people like me stumbling upon this thread searching for the right answer

For myself I got the following code and I guess a corrupt NSURL formatting since the AVAudioPlayer returned is nil:

Code:

NSString *dummyURLString = @"http://a825.phobos.apple.com/us/r2000/005/Music/d8/a8/d2/mzi.jelhjoev.aac.p.m4p";
NSError *error;
NSURL *url = [NSURL URLWithString:dummyURLString];	
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[player play];

And the &error shows the following:

Code:

Error Domain=NSOSStatusErrorDomain Code=-43 "Operation could not be completed. (OSStatus error -43.)"

Any suggestions???

Thanks!

Sorry dude. I was never able to get it to work. And I got no reply from the devforums at Apple. Wind up removing the feature from my app.

I still 100% sure there is a way. If iTunes and Safari are able to play it. I don't see why I can't get it to work in an app.

Hi I am facing same issue. I have tried with AvAudio player, UIWebView, AvPlayer. But at last not able to play that file. I have also posted question on developer forum but as you know no reply from them.

Do you find any solution?

Thanks,

The audio file encoded format is wrong, thats why you are getting this kind of issues.

Now I am developing an Audio Processing application for iPhone. I have faced this kind of more issues.
