Title
Body
An AVPlayerItem can only ever be assigned to one AVPlayer. Once an AVPlayerItem has been added to an AVPlayer, future attempts to add it to a different AVPlayer will SIGABRT the app. So, given an AVPlayerItem, how can you determine: What AVPlayer it is currently associated with? and If it has ever been inserted into an AVPlayer at any point in the past? The following code demonstrates the problem reliably: AVPlayerItem *item = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8"]]; AVPlayer *firstPlayer = [[AVPlayer alloc] init]; [firstPlayer replaceCurrentItemWithPlayerItem:item]; AVPlayer *secondPlayer = [[AVPlayer alloc] init]; [secondPlayer replaceCurrentItemWithPlayerItem:item]; And here's the error message: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'An AVPlayerItem cannot be associated with more than one instance of AVPlayer'
