I found that the player has increased support for ambient viewing environment SEI，this will lead to inconsistent display brightness of HDR streams processed in different ways。 I want to know the system version, software version and hardware version that support this SEI。In addition, are there other types of SEI syntax supported？

Hi! In Becoming a Now Playable App - https://developer.apple.com/documentation/mediaplayer/becoming_a_now_playable_app project for iOS target after changing playback rate to 2.0 (or any other value greater than 1.0) some bluetooth headphones fail to pause playback (for example Motorola Pulse Escape). The same issue manifests in other apps where playback speed change is allowed, but works well for Apple's Podcasts app. I tried to create custom UIWindow subclass to log all events received by OS, but iOS 13 doesn't receive pause command from headset at all (when playback is active and rate > 1.0), however skip backward/previous track make app work until you change rate back to 2. Does anyone have an idea how to make pause work in this case? Thanks!

I have a MUSIC website that uses the BetterAudioPlaylist front-end HTML5 player (https://github.com/NelsWebDev/BetterAudioPlaylist). For over 2 years it has worked flawlessly on my iPhone, however when I updated to iOS 12.1 it no longer advances to the next audio file if the screen is locked. I have tried going into Safari settings and used my troubleshooting skills to verify it has nothing to do with my settings. Is this Apple pushing out the little guy in favor of iTunes? Has anyone else had this problem? I contacted Apple's Developers support email, however they never responded. Please help!

How can I know the width and height of a video? For example, the video is playing and the screen is rotated.

let time1cmt = CMTimeGetSeconds(playerOK.currentTime()) time1 = Double(time1cmt) let time2cmt = CMTimeGetSeconds(playerOK.currentTime()) time2 = Double(time2cmt) videoDif = (time2 - time1) Now I'm using .currentTime() to get the start point and end point, but they don't seem to be accurate, is there any other way to get the time more accurately?

AVPlayer gets the list of URLs from the m3u8 file. I need to add some query string at the end of each URL. Is there any option in the AVPlayer to do this? Example: HLS URL : http://example.com/hls.m3u8 #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:10 #EXT-X-MEDIA-SEQUENCE:0 #EXTINF:10.417000,ts #EXTINF:10.417000,ts #EXTINF:9.470000,ts #EXTINF:10.417000,ts #EXTINF:9.470000,ts #EXTINF:10.417000,ts #EXTINF:9.470000,ts #EXTINF:3.840611,ts #EXT-X-ENDLIST AVPlayer is trying to download http://example.com/1.ts But I want the AVPlayer to add "?st=2020-09-01T13%3A59%3A03Z&se=2020-09-02T13%3A59%3A03Z&sp=rl&sv=2018-03-28&sr=b&sig=Pua9sv8mgvPF6gNwuBSghdEq%2BefMFmwBuyUdjCetmw4%3D" So AVPlayer will try http://example.com/1.ts?st=2020-09-01T13%3A59%3A03Z&se=2020-09-02T13%3A59%3A03Z&sp=rl&sv=2018-03-28&sr=b&sig=Pua9sv8mgvPF6gNwuBSghdEq%2BefMFmwBuyUdjCetmw4%3D instead of http://example.com/1.ts

I'm using AVPlayer for playing m3u8. I want to get more control over the download audio chunks - redownload chunk after a failed operation. If some chunks are unavailable, the player will still play without returning an error. Can you advise me on some articles, maybe examples?

Im using more easily to create a pick up and play a video, and that part works, and to show the video I use this line: PhotoPickerResultView(result: photoPickerService.results[0]) and this part work fine to, arrives from this: struct PhotoPickerResultView: View {       var result: PHPickerResult       enum MediaType {     case loading, error, video   }       @State private var loaded = false   @State private var url: URL?   @State private var mediaType: MediaType = .loading   @State private var latestErrorDescription = ""       var body: some View {           Group {       switch mediaType {       case .loading:         ProgressView()       case .error:         VStack {           Image(systemName: "exclamationmark.triangle.fill")           Text(latestErrorDescription).font(.caption)         }         .foregroundColor(.gray)       case .video:         if url != nil {                                 VideoPlayer(player: AVPlayer(url: url!))          ... ..... My question is, How can I use or implement the custom buttons of the AVPlayer? like: @State private var player1 = AVPlayer(url: URL(string: "https...mp4")!)          VideoPlayer(player: player1)                   Button {           player1.play()         } label: {           Text(" PLAY ")         }         Button {           player1.pause()         } label: {           Text(" PAUSE ")         } from this line: PhotoPickerResultView(result: photoPickerService.results[0]) ??? or what do I have to change to use more easily that custom buttons of the AVPlayer?? Thanks

Hello, I'm the developer of an Apple Music app called Soor, I've been recently working on adding Catalyst support to the app. However, I've noticed some severe bugs while setting the queue for playing non-library items on macOS 12.2. Both MPMusicPlayerPlayParametersQueueDescriptor and MPMusicPlayerStoreQueueDescriptor fail to play items using valid playbackStore identifiers. The console logs the following errors: [SDKPlayback] systemMusicPlayer _establishConnectionIfNeeded timeout [ping did not pong] `[SDKPlayback] Failed to prepareToPlay error: Error Domain=NSOSStatusErrorDomain Code=9205 "(null)"` I have filed radars for this along with sample projects showcasing the issue. FB9890270 and FB9890331. Here's a gist of the sample code for which the player either completely fails to set the queue or now playing item stays nil. /// These are valid playback store ids retrieved from Apple Music API. /// You may replace them with any valid playback store IDs of your choice. let playbackStoreIDs = ["1588418743", "1604815955", "1596475453", "1562346959", "1596475469", "1596475460", "1580955750", "1591442362", "1607324602", "1531596345"] var playParams = [MPMusicPlayerPlayParameters]() for playbackStoreID in playbackStoreIDs { let param = MPMusicPlayerPlayParameters(dictionary: ["id": playbackStoreID, "kind": "song"])! playParams.append(param) } let queueDesc = MPMusicPlayerPlayParametersQueueDescriptor(playParametersQueue: playParams) queueDesc.startItemPlayParameters = playParams[3] player.setQueue(with: queueDesc) player.play() Has anyone managed to playback music correctly using only playback store ids on Catalyst?

I use encrypted contents in my app . Before playing I request for decryption key which helps in playing content online . I want to play content offline too . So I download the content. But how can I store decryption keys ?

So I am trying to add two buttons to the view of my SwiftUI app that will allow a user to fast forward and rewind the audio clip. I already have it working on the Lock Screen and notification bar, but in the app I can't figure out how to link two buttons to these actions. I am wondering if anyone is able to assist. In the MusicCore.swift I have the following func setupRemoteTransportControls() { // Get the shared MPRemoteCommandCenter let commandCenter = MPRemoteCommandCenter.shared() let changePlaybackPositionCommand = commandCenter.changePlaybackPositionCommand changePlaybackPositionCommand.isEnabled = true changePlaybackPositionCommand.addTarget { event in let seconds = (event as? MPChangePlaybackPositionCommandEvent)?.positionTime ?? 0 let time = CMTime(seconds: seconds, preferredTimescale: 1) self.player?.seek(to: time) return .success } let skipBackwardCommand = commandCenter.skipBackwardCommand if(MusicPlayer.mediatype == "podcast") { skipBackwardCommand.isEnabled = true skipBackwardCommand.preferredIntervals = [NSNumber(value: 10)] skipBackwardCommand.addTarget(handler: skipBackward) } else{ skipBackwardCommand.isEnabled = false } let skipForwardCommand = commandCenter.skipForwardCommand if(MusicPlayer.mediatype == "podcast") { skipForwardCommand.isEnabled = true skipForwardCommand.preferredIntervals = [NSNumber(value: 30)] } else{ skipForwardCommand.isEnabled = false } skipForwardCommand.addTarget(handler: skipForward) // Add handler for Play Command commandCenter.playCommand.addTarget { [unowned self] event in if self.player?.rate == 0.0 { self.player?.play() return .success } return .commandFailed } // Add handler for Pause Command commandCenter.pauseCommand.addTarget { [unowned self] event in if self.player?.rate == 1.0 { self.player?.pause() MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!)) return .success } return .commandFailed } func skipBackward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus { //self.player?.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: -30), preferredTimescale: 1)) // print(CMTimeGetSeconds((self.player?.currentTime())!)) //Output: 42 //print(event.interval) //self.player!.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: -30), preferredTimescale: 1)) let currentTime = self.player?.currentTime() self.player?.seek(to: CMTime(seconds: currentTime!.seconds - 10, preferredTimescale: 1), completionHandler: { isCompleted in if isCompleted { MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!)) } }) return .success } func skipForward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus { //self.player?.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: 30), preferredTimescale: 1)) let currentTime = self.player?.currentTime() self.player?.seek(to: CMTime(seconds: currentTime!.seconds + 30, preferredTimescale: 1), completionHandler: { isCompleted in if isCompleted { MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!)) } }) return .success } } But how can I call that from inside a View?

Hello, https://stackoverflow.com/questions/51797343/setting-http-header-fields-for-avurlassets Is it okay to use the method using "AVURLAssetHTTPHeaderFieldsKey" described on this page?

Is there any way of discovering the name of the device when the user started to cast to it? The only thing I found was this let route = AVAudioSession.sharedInstance().currentRoute for output in route.outputs where output.portType == .airPlay { infoDict["deviceName"] = output.portName infoDict["portType"] = output.portType.rawValue } but the output.portName returns the portType instead of the portName.

Attempting to pull a podcast, via it's ID, leads to a CORS error, as it has the response header: access-control-allow-origin: http://localhost:3000 Meaning, locally, I am able to pull the required podcast episode list, but as soon as I am in staging or production, the whole thing falls over. Has anyone come across this issue, and does anyone have any work arounds?
