Accessing URL from AVPlayer object?

avplayer, ios

Solution

An `AVPlayer` plays an `AVPlayerItem`. `AVPlayerItem`s are backed by objects of the class `AVAsset`. When you use the `playerWithURL:` method of `AVPlayer` it automatically creates the `AVPlayerItem` backed by an asset that is a subclass of `AVAsset` named `AVURLAsset`. `AVURLAsset` has a `URL` property.

So, yes, in the case you provided you can get the `NSURL` of the currently playing item fairly easily. Here's an example function of how to do this:

-(NSURL *)urlOfCurrentlyPlayingInPlayer:(AVPlayer *)player{
    // get current asset
    AVAsset *currentPlayerAsset = player.currentItem.asset;
    // make sure the current asset is an AVURLAsset
    if (![currentPlayerAsset isKindOfClass:AVURLAsset.class]) return nil;
    // return the NSURL
    return [(AVURLAsset *)currentPlayerAsset URL];
}

Not a swift expert, but it seems it can be done in swift more briefly.

func urlOfCurrentlyPlayingInPlayer(player : AVPlayer) -> URL? {
    return ((player.currentItem?.asset) as? AVURLAsset)?.url
}

Problem

Is there a way to access the URL from an AVPlayer object that has been initialized with a URL, as in: ``` NSURL *url = [NSURL URLWithString: @"http://www.example.org/audio"]; self.player = [AVPlayer playerWithURL: url]; ```
