CachingPlayerItem crashes on iOS 14

[MrdotSpock]

Hi,

Whenever I initialize CachingPlayerItem the app crashes because alsooverride init(asset: AVAsset, automaticallyLoadedAssetKeys: [String]?) is called multiple times. But this initializer is not implemented. I tried to implement it myself but it creates a huge delay before the playing starts and I don't know which track I should play anyway.

This happens only on iOS 14. I've checked multiple times that I do not call the initializer myself and I really don't understand why it is happening. It seems like multiple instances of CachingPlayerItem are being created. (One with correct initializer and the rest with this one) Does anyone else also encounter this issue? Did anyone find a solution?

Thanks

This issue still persists on iOS 14.7 as well.

If I setup a playerItem -> CachingPlayerItem, and set it to some AVPlayer or AVQueuePlayer it plays fine.

but when I try to launch it for next cells/items in my pagerViewCotroller, it does not start download automatically and when user scrolls to next page or cell/item -> it crashes with fatalError breakpoint on line

override init(asset: AVAsset, automaticallyLoadedAssetKeys: [String]?) { fatalError("not implemented") }

Can we have a quick look into this.

+1 this is still broken.

It appears AVQueuePlayer and AVPlayerLooper are not compatible with this project

I was able to solve this issue by adding override of the init it is complaining about:

override init(asset: AVAsset, automaticallyLoadedAssetKeys: [String]?) {
   self.url = URL(fileURLWithPath: "")
   super.init(asset: asset, automaticallyLoadedAssetKeys: automaticallyLoadedAssetKeys)
 }

Making sure to set empty URL before super.init call.

i had to add these lines too for @QEllis 's answer:

override init(asset: AVAsset, automaticallyLoadedAssetKeys: [String]?) {
        self.url = URL(fileURLWithPath: "")
        self.initialScheme = nil
        super.init(asset: asset, automaticallyLoadedAssetKeys: automaticallyLoadedAssetKeys)

        addObserver(self, forKeyPath: "status", options: NSKeyValueObservingOptions.new, context: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(playbackStalledHandler), name:NSNotification.Name.AVPlayerItemPlaybackStalled, object: self)

     }

To everyone with this issue. When initializing your playerItem use:

let playerItem = CachePlayerItem(url: url, avUrlAssetOptions: nil) <<< make sure to set this to nil

This is the incorrect one to use and what causes the crash

let playerItem = CachePlayerItem(url: url) <<< DON'T USE THIS alone without the avUrlAssetOptions param

The solution given by @QEllis and @dreampowder works even when you are using AVQueuePlayer and AVPlayerLooper.

Thanks @lsamaria! This solution works for me

Big thanks! 🙏
