[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemBecameCurrent:)
                                             name:@"AVPlayerItemBecameCurrentNotification"
                                           object:nil];


- (void)playerItemBecameCurrent:(NSNotification*)notification 
{
        AVPlayerItem *playerItem = [notification object];
        if(playerItem == nil) return;

        // Break down the AVPlayerItem to get to the path
        AVURLAsset *asset = (AVURLAsset*)[playerItem asset];
        NSURL *url = [asset URL]; // this is URL you need
}
