MPRemoteCommandCenter likeCommand and dislikeCommand
I'm trying to show likeCommand and dislikeCommand on the Lock Screen of a music player without success. Are they still supported ? Is there any special configuration on the player or the track for them to show? My current code which works for playCommand looks like this MPRemoteCommandCenter.shared().likeCommand.addTarget { [unowned self] _ in if isPlaying { return .success } return .commandFailed }

"outputObscuredDueToInsufficientExternalProtection" state of this flag always remains one (not zero) even when the playback is successful
Our initial understanding was that this event is fired only when the DRM blocks the video playback. However, in the present case we see that it is called even when playback is successful(playback with external screen connected). To assess whether playback remains functional when the 'outputObscuredDueToInsufficientExternalProtection' event is triggered, we conducted two specific scenario tests: 1) playing an asset without any DRM restrictions, and 2) playing an asset with DRM restrictions. Result: In our analysis, we have identified that the 'outputObscuredDueToInsufficientExternalProtection' flag always remains set to one, even when playback is successful. However, it is expected to be set to zero when the playback is successful. working case log when playback is successful: default 13:23:19.096682+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281284930> change kind = { kind = 1; new = 1; old = 0; } non working case log when playback came as black screen: default 13:45:21.356857+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281c071e0> change kind = {kind = 1; new = 1; old = 0; } We searched through related documents and conducted a Google search, but we couldn't find any information or references related to this behavior of the 'outputObscuredDueToInsufficientExternalProtection' event. It would be really appreciated if any one can help us with this!

"outputObscuredDueToInsufficientExternalProtection" state of this flag always remains true even though output is not obscured.
We have a logic in the SDK which stops playback when the outputObscuredDueToInsufficientExternalProtection event is fired by the player. Our initial understanding was that this event is fired only when the DRM blocks the video playback. However, in the present case we see that it is called even when playback is successful(playback with external screen connected). To determine whether playback still functions when the 'outputObscuredDueToInsufficientExternalProtection' event is triggered, we temporarily disabled the playback stop implementation that occurs after the event is triggered. code snippet - Observations - After this event was triggered during mirroring playback using a Lightning to HDMI connector, our expectation was that the playback would result in a black screen. However, to our surprise, the playback worked perfectly, indicating that this event is being triggered even when there are no DRM restrictions for that asset's playback. Another scenario we tested involved using a VGA connector. In this case, we observed that the 'outputObscuredDueToInsufficientExternalProtection' event was triggered. Initially, playback started as expected when we commented out the playback stop implementation. However, after a few seconds of playback, the screen went black. In the first scenario, it was unexpected for the 'outputObscuredDueToInsufficientExternalProtection' event to trigger, as the playback worked without issues even after the event was triggered. However, in the second scenario, the event was triggered as expected. The issue we identified is that this event is being triggered irrespective of the presence of DRM restrictions for the asset. In another scenario, we attempted to differentiate between the VGA and HDMI connectors to determine if such distinction was possible. However, we found that the VGA cable was also recognized as an HDMI port in the case of iOS. We also tested the issue on an older iOS version (iOS 14.6.1) to see if the problem persisted. Surprisingly, we found that the 'outputObscuredDueToInsufficientExternalProtection' event was triggered even in the older OS version. Conclusion: In our analysis, we have identified that the 'outputObscuredDueToInsufficientExternalProtection' flag always remains true even though output is not obsecured. working case log: default 13:23:19.096682+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281284930> change kind = { kind = 1; new = 1; old = 0; } non working case log: default 13:45:21.356857+0530 AMC ||| observeValueForKeyPath = "outputObscuredDueToInsufficientExternalProtection" object = <AVPlayer: 0x281c071e0> change kind = {kind = 1; new = 1; old = 0; } We searched through related documents and conducted a Google search, but we couldn't find any information or references related to this behavior of the 'outputObscuredDueToInsufficientExternalProtection' event.

The application that I'm building creates a audioContext and audio elament. after that creates a buffer for type 'audio/mp4; codecs="mp4a.40.2'. and trys to fetch chunks of data into it. after the first chunk is loaded it starts playing. It works on my Mac and iPad I also tested on android. Hello, I'm developing a PWA (Progressive Web App). This app needs to use some features of the Audio API.

HtmlVideoElement Suspended on iOS Safari
We have a web application which is having stalled html video element issue on iOS Safari. iOS Version 17.0.3. The html page contains a inline script tag for example <script> ... </script> and runs immediately when page loads. The script does following videoElement.src = url; videoElement.load(); The url is a HLS manifest url. After the DOM elements are created, we attatch the videoElement to a <div> and expecting the video reaches canplaythrough eventually and starts to playing. Actual Behavior: The video never plays videoElement readyState and networkState both stuck at value of 1 we found that "suspened" event was triggered on the video element and not sure who is triggering it. Temporary Mitigation: When video is stalled, if we call videoElement.load() manually in Safari js console, the readyState and networkState will increase and seeing HLS video segment are being fetched and video eventually reaches canplaythrough. This happens only on iOS Safari, not MacOS Safari. We suspect its because at begining when videoElement.src is set and .load() was called, the videoElement was not attached to any div so iOS decides to stop it to save battery. But its completely uneducated guess and any help would be appreciated. Thanks !

Can't set Album artwork on MPNowPlayingInfoCenter without setting allowsExternalPlayback = false
I have an AVPlayerViewController in my app to play custom audio+image or video streamed from an online service. If I set the below, I am able to add info to the nowPlayingInfo dictionary avplayerController.updatesNowPlayingInfoCenter = false This works for iOS control centre, it correctly displays my custom album name, artwork etc. But when using airplay for audio, it only displays the track name while playing audio. It doesn't display the artwork or the album etc. However if I set avplayerController.player?.allowsExternalPlayback = false It does correctly display artwork, title, album etc. This however disables the airplay button thats inbuilt on the player. I would like this button to remain, but need the artwork to be displayed while airplay-ing. How to I achieve this?

How to trigger music playback in Widget
Hello, I have a music player application that uses MPMusicPlayerController to play Apple Music songs. Now I want to add a Widget to it that can trigger playback pause on iOS 17. How do I need to achieve this? I can get the playbackStoreID of the song on the Widget Extension and use MPMusicPlayerController setQueue(with:) to play it. How do I pass the playbackStoreID in the Widget to the main application for playback, or should I create a new MPMusicPlayerController on the Widget Extension for playback?

Books Appears Broken In MacOS Sonoma Beta
Typically when uploading ePubs into Books all that was required was to drag them either into the app directly or onto the Books icon. In MacOS Sonoma Books accepts ePubs but rejects them about a minute or two later. Curious about this behavior I went to the folder where ePubs are stored, and moved the books directly to it instead of via the Books app. Once you move them into the folder, the same behavior that you see in the app happens with the folder (books appear in the folder, then vanish from the folder a minute or two later).

Podcasts URL scheme does not follow podcast due to HTTP URL
Hello! In our website, we allow members to follow private RSS feeds on their Podcasts app easily with the click of a button. Underneath the button is a link in the format of: podcast://example.rssurl.com # Example With this URL scheme, the Podcasts app launches correctly and shows the "Follow a Show by URL" input box, with the private RSS feed URL prefilled. However, the prefilled URL uses HTTP instead of HTTPS. So, the example link above (podcast://example.rssurl.com) when clicked is converted to: http://example.rssurl.com in the "Follow a Show by URL" input box in the Podcasts app. We noticed the HTTP form of the URL does not work well, as it sometimes fail to follow the show. Clicking on "Follow" would simply close the box and cause nothing to happen, not even error messages. We then tested with HTTPS by manually inserting the URL like so: https://example.rssurl.com and this would always work. However, this is not ideal as our users would have to manually paste in the URL all the time. It'd be great if the Podcasts URL scheme above would automatically prefill the "Follow a Show by URL" input box with the HTTPS form instead. Is there a way to force this behavior or is this intended from Apple's side? Thank you!

Shared AVAudioPlayer State Between App and Widget: How does Apple Music Do It?
Hello Everyone, I'm working on creating an audio playback widget for my app, aiming for functionality similar to the Apple Music widget. Specifically, I've implemented a play button in my widget that triggers an AudioPlaybackIntent. This intent then interacts with a singleton class that manages my AVAudioPlayer. The issue I'm facing is that the AVAudioPlayer instance in my main app and the instance in my widget extension don't seem to share the same state. I've noticed that the Apple Music widget is capable of showing real-time changes (eg. stopping music from command center, stops it on widget UI), which implies that it has some way of sharing the playback state between the main app and the widget. How can I achieve shared state between the main app and widget for my AVAudioPlayer instance? Is there a specific approach or API that Apple Music uses to make this happen?

AVPlayer Subtitle Styling
In our application, we play video-on-demand (VOD) content and display subtitles in different languages. The format we prefer for subtitles is WebVTT. We are planning to enhance caption styling (text color, background color, font weight, etc.) in WebVTT files. In our current flow, subtitles and images are loaded in 6-second chunks. Below is an example of one of the subtitle parts we use: WEBVTT X-TIMESTAMP-MAP=MPEGTS:0,LOCAL:00:00:00.000

iOS MPVolumeView Not Responding to Hardware Volume Changes After Audio Streaming Starts
I've integrated MPVolumeView into my view, and it correctly responds to hardware volume changes as expected. However, once I initiate audio streaming using AVAudioEngine to capture microphone audio and AudioUnit for decoding, the MPVolumeView ceases to reflect changes made using the hardware volume buttons. Additionally, even when I adjust the volume using the slider on MPVolumeView, it doesn't change the system volume. Has anyone else encountered this issue? What might be causing MPVolumeView to stop responding to hardware volume changes once streaming starts? For the AVAudioSession.Mode, I use the default setting because using .voiceChat prevents MPVolumeView update from device volume changes permanently. let session = AVAudioSession.sharedInstance() do { try session.setCategory(.playAndRecord, options: [.allowBluetooth]) try session.setActive(true) } catch { print(error.localizedDescription) }
