Xcode AVPlayer crash iPhone 5 - Titanium iOS Module - objective-c

Question

i have written an Titanium iOS Module for streaming audio.
On iPhone 5s and above the app and the module is running great.
The problem is every time the stopStream function is called in my app on an iPhone 5 or lower the app crashes.
I think there is a memory leak or something but i doesnt find the solution for that problem.
Here is my module code:
//THIS FUNCTION THET STARTS THE STREAM. THERE IS NO PROBLEM ON THE IPHONE 5
-(id)startStream:(id)args
{
ENSURE_SINGLE_ARG(args,NSString);
NSURL *url = [NSURL URLWithString:args];
playerItem = [AVPlayerItem playerItemWithURL:url];
[playerItem addObserver:self forKeyPath:#"timedMetadata" options:NSKeyValueObservingOptionNew context:nil];
player = [[AVPlayer playerWithPlayerItem:playerItem] retain];
[player addObserver:self forKeyPath:#"status" options:0 context:nil];
[player play];
[self fireEvent:#"START" withObject:nil];
NSLog(#"[INFO] player item error : %#", playerItem.error.description);
NSLog(#"[INFO] player error : %#", player.error.description);
return args;
}
//THIS IS THE FUNCTION WHERE MY APP CRASH ON IPHONE 5
-(id)stopStream:(id)args
{
NSLog(#"[INFO]AVPlayer STOP");
[player pause];
[playerItem removeObserver:self forKeyPath:#"timedMetadata" context:nil];
[player removeObserver:self forKeyPath:#"status" context:nil];
player=nil;
}
Here an part of the device log.

Answer 1

i found the solution for my problem.
i must add an return in the function.
Now it is working for iPhone5 and lower
-(id)stopStream:(id)args
{
NSLog(#"[INFO]AVPlayer STOP");
[player pause];
[playerItem removeObserver:self forKeyPath:#"timedMetadata" context:nil];
[player removeObserver:self forKeyPath:#"status" context:nil];
return args;
}

Answer 2

You're also over retaining the player. You should [player release]; in your stopStream, or in startStream, only instantiate a new player if one does not already exist.
