Here we are focusing to change the cookie at every 120 seconds while playing , in apple avplayer we can't modify cookie after initialisation due to that we followed the approach to using " Resource loader delegate " to pass cookie as a header value . What I notice is that the playlist file (.m3u8) gets downloaded correctly. Then video file (.m4a) some chunks also gets downloaded. I know that the .ts file is downloaded because I can see the GET request completing on the web server with status 200. I also set a breakpoint at the following line: loadingRequest.dataRequest?.respond(with: data) immediately got error from avplayer status as "The operation could not be completed. An unknown error occurred (-12881) From core media" Need confirmation on why I am unable to load HLS using resource loader. is it possible to update cookie value while paying continuously on avplayer. override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. let urlString = "localhost://demo.unified-streaming.com/k8s/features/stable/video/tears-of-steel/tears-of-steel.ism/.m3u8" guard let url = URL(string: urlString) else { print("Invalid URL") return } //Create cookie to prepare for player asset let cookie = HTTPCookie(properties: [ .name: "dazn-token", .value: "cookie value", .domain: url.host() ??

Can some one please answer me How Can I update the cookies of the previously set m3u8 video in AVPlayer without creating the new AVURLAsset and replacing the AVPlayer current Item with it
