I need to download encrypted HLS stream in tvos and save it in local file path. But AVAssetDownloadURLSession is not available in tvOS. Is there any alternative?. Thanks

I reset the old player item(remove all observers also) and avplayercontroller then add a new avplayerviewcontroller instance and avplayer and player item on playing a new asset/stream etc. It works fine and no crash in tvos 14, 13 etc. But in tvos 15.2 and above i get the following stack trace. Below are the details i could collect from firebase, please check if it could help you to infer the cause of the crash. Thanks!

let data = try JSONDecoder().decode([User].self, from: jsonData) On analysing the memory leaks with instrument tool, this particular code always shows memory leak. Any help to resolve this issue. Note: User model is nested struct

self.avplayercontroller.customInfoViewController = nil Using the nil assigning method removes the options menu but crashes intermittenly - "Fatal Exception: NSInvalidArgumentException** -[__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0]" Is there any other option to hide/remove options tab when needed in avplayerviewcontroller. Radar bug which I noticed is resolved but I still get the issue intermittenly. https://openradar.appspot.com/48192193

What could be the reason for the crash ?. Is it some memory issue?
