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).

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!

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) }

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?

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

Hi. I am transitioning my app from using MPMediaQuery to using MusicLibraryRequest from MusicKit. This is working fine for playlists in the user's library. I also allow my app users to play their podcasts. I currently use MPMediaQuery.podcasts(). Does anyone know if there is an equivalent using MusicLibraryRequest? Cheers, Ian

There’s an unexpected behaviour when using the append(_:) & prepend(_:) methods on iOS 17 Beta 6 and Public Beta 4. Observed Behaviour When queuing using the mentioned methods on recent iOS 17 Betas, the supplied music isn‘t queued up and the now playing music pauses. When using applicationQueuePlayer, it even ends up crashing the app. FB13010449 Sample Project

Is it possible to completely remove the before/next buttons from the CPNowPlayingTemplate? I've already tried to set live-streaming mode, but the buttons are still there.

Hello, We are using HLS for our streaming iOS and tvOS applications. We have DRM protection on our applications but we want add another secure layer which is CDN token. We want to add that CDN token data on header or query parameters. Any of two are applicable at our CDN side. There is a problem at client side. We want to send that token knowledge and refresh at given a time. We add token data using at initial state let asset = AVURLAsset(url: url, options: ["AVURLAssetHTTPHeaderFieldsKey": headers]) and add interceptor with asset.resourceLoader.setDelegate. It works seamlessly. We use AVAssetResourceLoaderDelegate and we can intercept just master playlist and playlists via func resourceLoader(_ resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool and we can refresh CDN token data at only playlists. That token data can be at query params or header. It does not matter. For example, #EXTM3U #EXT-X-VERSION:3 #EXTINF:10.0 https://chunk1?cdntoken=A.ts #EXTINF:10.0 https://chunk2?cdntoken=A.ts #EXTINF:10.0 https://chunk3?cdntoken=A.ts #EXTINF:10.0 assume that it is our .m3u8 file for given live video playlist. It has three chunks with cdn token data in query params. If we give that chunks to AVPlayer. It is going to play chunks in order. When we change new cdn token at query params, it effects our chunk Urls and our player stalls. It is because our cdn adds new cdn token knowledge to chunk's Url. It means that our new .m3u8 is going to be like that for next playlist; #EXT-X-VERSION:3 #EXTINF:10.0 https://chunk4?cdntoken=B.ts #EXTINF:10.0 https://chunk5?cdntoken=B.ts #EXTINF:10.0 https://chunk6?cdntoken=B.ts #EXTINF:10.0 Cdn token data is converted to B from A at cdn side and it sends new playlist like that. That's why, our player is going to stall. Is there any way not to player stall with edited chunk url? When we change new cdn token at header. It does not change chunks url like at the first question but AVPlayer does not allow to intercept chunk Urls which means that before callin https://chunk1?cdntoken=A.ts url, i want to intercept and add new cdn token data to header. Is there any way to intercept chunk Urls like intercepting playlist? Thanks for answers in advance

Problem Description This HLS video https://lf3-vod-cdn-tos.douyinstatic.com/obj/vodsass/hls/main.m3u8 starts with noise at 22 seconds play directly on MacOS 12.6.6 Safari，and it also appears on iOS (16.5.1) safari. But there is no noise when playing with MSE on Mac by the third-party open source web playe such as hls.js on Safari. Test tool hls.js test demo: https://hlsjs.video-dev.org/demo/

Hi I'm developing a full-duplex iPhone voice chat application and I'd like to intercept bluetooth headset button events to perform certain actions in my app while maintaining a full-duplex audio. I'm using the MediaPlay to intercept remote bluetooth AVRCP MPRemoteCommandEvent play/pause events as well setting AVAudioSession to use the BluetoothA2DP category, however, when I do this, I can't seem to use the bluetooth microphone as an audio input. Specifically, when I query AVAudioSession for available inputs, bluetooth is not returned. I'm guessing this is because A2DP is a half-duplex protocol, but my understanding is that AVRCP events are only available with A2DP. The other bluetooth profile choice is HSP (AVAudioSession category Bluetooth), which works for full-duplex audio, but does not appear to provide a way to intercept the various AT commands from this profile unless I'm in an actual telephone call. For example, when I use HSP and press a button on my headset, I see in the logs the AT+CHUP command being sent from the headset to the phone. Two questions: Is there a way to use a bluetooth microphone while using A2DP for output at the same time? If the above can't be done, is there a way to intercept the HSP AT control commands from a headset without being in a telephone call? Thanks.

I'm getting the following error in Xcode and I can't figure out how to fix it. Cannot load underlying module for 'MediaPlayer' I've searched Google and have come across lots of other people with similar issues whereby they're importing something and it's producing this error alongside it. https://stackoverflow.com/questions/76256875/cannot-load-underlying-module-for-scenekit https://developer.apple.com/forums/thread/115059 https://stackoverflow.com/questions/32673866/cocoapods-cannot-load-underlying-module-for-x The error is being shown inline with this bit of code: import SwiftUI import MusicKit import MediaPlayer <-- this line here I can build and run the project without issue and it disappears. But will quickly reappear again a short while later and it's very annoying. How can I resolve this please?

We are using AVPlayerViewController to display/play video. Till iOS 15 video player options are visible but for iOS 16 it's not visible. Do we require to make changes for iOS 16 to display video player options?

I have noticed changes Apple Music made to my library, take in particular a changed album edition that is reflected in how the title is listed. I can see the new title in the Music app in two different devices. On one device MPMediaQuery returns the album with the new title. The other device (an iPad with less memory, in case that matters) is still returning the old edition. Is there anything I can do to make sure the data returned is up to date and matches what is seen in the Music app?

I imported the MediaPlayer framework and used MPMusicPlayerPlayParameters in my SwiftUI project. While the app is launching, If the app is built by Xcode 14.3.1 or a newer version, it instantly crashes on a simulator or on a real device. This problem persists on iOS 16.0 to 16.4. (I haven't tried iOS 15 or below) I also tried to build and run the app with Xcode 15 - beta 4 however it still crashes. Because of this reason, I archive and submit to App Store with Xcode 14.2. (the built made by Xcode 14.2 works perfectly!!) Here is the error message: dyld[17235]: Symbol not found: _$sSo27MPMusicPlayerPlayParametersCSe05MediaB0Mc Referenced from: <77FEF170-9C51-3580-8F8B-2ADD2F1B3FD1> /Users/[UserName]/Library/Developer/CoreSimulator/Devices/72CE26D8-4DD4-4319-B0C7-DE52D6645875/data/Containers/Bundle/Application/C808623F-5372-40F0-907F-E86E12AE6EDD/[AppName].app/[AppName] Expected in: <06F636E1-695C-34F1-809D-7CA24F67AFE9> /Library/Developer/CoreSimulator/Volumes/iOS_20B72/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.1.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/MediaPlayer.framework/MediaPlayer I believe this is Apple related issue however if there is any way that can fix the issue, please let me know.
