What is error -12865 when trying to play a video?

Hello,

I'm trying to play a stream video after I downloaded it using a AVAssetDownloadURLSession and aggregateAssetDownloadTask.

When I initialise the AVPlayerItem with the AVURLAsset saved locally in the bookmarks it get the -12865 error. What does this code stands for?

If I play the video directly from the stream it works fine.

This is the code that saves the asset:

Code Block /// Tells the delegate that the task finished transferring data.    func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {        let userDefaults = UserDefaults.standard        /*         This is the ideal place to begin downloading additional media selections         once the asset itself has finished downloading.         */        guard let task = task as? AVAggregateAssetDownloadTask,            let asset = activeDownloadsMap.removeValue(forKey: task) else { return }        guard let downloadURL = willDownloadToUrlMap.removeValue(forKey: task) else { return }        // Prepare the basic userInfo dictionary that will be posted as part of our notification.        var userInfo = [String: Any]()        userInfo[Asset.Keys.name] = asset.name        if let error = error as NSError? {            switch (error.domain, error.code) {            case (NSURLErrorDomain, NSURLErrorCancelled):                /*                 This task was canceled, you should perform cleanup using the                 URL saved from AVAssetDownloadDelegate.urlSession(_:assetDownloadTask:didFinishDownloadingTo:).                 */                guard let localFileLocation = localAsset(withName: asset.name)?.urlAsset.url else { return }                do {                    try FileManager.default.removeItem(at: localFileLocation)                    userDefaults.removeObject(forKey: asset.name)                } catch {                    print("An error occured trying to delete the contents on disk for \(asset.name): \(error)")                }                userInfo[Asset.Keys.downloadState] = Asset.DownloadState.notDownloaded.rawValue            case (NSURLErrorDomain, NSURLErrorUnknown):                fatalError("Downloading HLS streams is not supported in the simulator.")            default:                fatalError("An unexpected error occured \(error.domain)")            }        } else {            do {                let bookmark = try downloadURL.bookmarkData()                userDefaults.set(bookmark, forKey: asset.name)            } catch {                print("Failed to create bookmarkData for download URL.")            }            userInfo[Asset.Keys.downloadState] = Asset.DownloadState.downloaded.rawValue            userInfo[Asset.Keys.downloadSelectionDisplayName] = ""        }        NotificationCenter.default.post(name: .AssetDownloadStateChanged, object: nil, userInfo: userInfo)    }    /// Method called when the an aggregate download task determines the location this asset will be downloaded to.    func urlSession(_ session: URLSession, aggregateAssetDownloadTask: AVAggregateAssetDownloadTask,                    willDownloadTo location: URL) {        /*         This delegate callback should only be used to save the location URL         somewhere in your application. Any additional work should be done in         `URLSessionTaskDelegate.urlSession(_:task:didCompleteWithError:)`.         */        willDownloadToUrlMap[aggregateAssetDownloadTask] = location    }

and this one get's the asset back

Code Block let userDefaults = UserDefaults.standard        guard let localFileLocation = userDefaults.value(forKey: name) as? Data else { return nil }                var bookmarkDataIsStale = false        do {            let url = try URL(resolvingBookmarkData: localFileLocation,                                    bookmarkDataIsStale: &bookmarkDataIsStale)            if bookmarkDataIsStale {                fatalError("Bookmark data is stale!")            }                        return AVURLAsset(url: url)        } catch {            fatalError("Failed to create URL from bookmark with error: \(error)")        }

Thank you
