Hi, Has anyone been able to protect the audio part of FairPlay protected content from being captured as part of screen recording on Safari/iOS (PWA and/or online web app)? We have tried many things but could not prevent the audio from being recorded. Same app and content on Safari/Mac does not allow audio to be recorded. Any tips?

Hello Apple Developer Support, I am reaching out for technical guidance regarding screen capture protection behavior on macOS. We are building a desktop application using Flutter running on macOS, and we have implemented native Swift code inside the macOS Runner in order to protect sensitive content from screen recording and screen sharing. Our current implementation relies on native window-level protection and display state handling from Swift, while the main UI remains rendered by Flutter. The main challenge we are facing is the following: we need to keep a strong native anti-recording protection on macOS the application is heavily used with AirPlay and screen mirroring currently, AirPlay / mirroring is often interpreted by the system similarly to screen capture or screen recording this causes our protected content to be replaced by a gray or blank area even during legitimate AirPlay usage In practice, we would like to allow: AirPlay legitimate external display / mirroring usage while still preventing: screen recording screen sharing unauthorized screen capture We would like to know whether Apple recommends an official supported approach for this use case, preferably using public APIs. More specifically: Is there an officially supported way on macOS to distinguish AirPlay mirroring from screen recording / screen sharing? Is "NSWindow.sharingType" the recommended public API for this scenario? Is there a recommended approach when the UI surface is rendered through Flutter / Metal? Are there any best practices with ScreenCaptureKit for protecting content without affecting AirPlay? We understand that some lower-level APIs may not be officially supported, so we would greatly appreciate guidance toward a public and future-proof implementation path. Thank you very much for your time and support. Best regards, Tony

We are developing a video streaming app that uses AVContentKeySession with FairPlay Streaming. Our implementation supports both online playback (non-persistable keys) and offline playback (persistable keys). We have observed the following behavior: Once a content key has been obtained for a given Content Key ID, AVContentKeySession does not trigger contentKeySession(_:didProvide:) again for that same Key ID We also attempted to explicitly call processContentKeyRequest(withIdentifier:initializationData:options:) on the session to force a new key request for the same identifier, but this did not result in the delegate callback being fired again. The session appears to consider the key already resolved and silently ignores the request. This means that if a user first plays content online (receiving a non-persistable key), and later wants to download the same content for offline use (requiring a persistable key), the delegate callback is not fired again, and we have no opportunity to request a persistable key. Questions Is this the expected behavior? Specifically, is it by design that AVContentKeySession caches the key for a given Key ID and does not re-request it — even when processContentKeyRequest(withIdentifier:) is explicitly called? Should we use distinct Content Key IDs for persistable vs. non-persistable keys? For example, if the same piece of content can be played both online and offline, is the recommended approach to have the server provide different EXT-X-KEY URIs (and thus different key identifiers) for the streaming and download variants? Is there a supported way to force a fresh key request for a Key ID that has already been resolved — for example, to upgrade from a non-persistable to a persistable key? Environment iOS 18+ AVContentKeySession(keySystem: .fairPlayStreaming) Any guidance on the recommended approach for supporting both streaming and offline playback for the same content would be greatly appreciated.

Hello, I used AVPlayer in my project to play network movie. Most movie could play normally, but I found the sound will disappear sometimes if I play specified 4K video network stream. The video will continue playing but audio stops after video is played for a while. If I pause player and then resume, the sound will be back but disappeared again after several seconds Check AVPlayerItem status: isPlaybackLikelyToKeepUp` == true isPlaybackBufferEmpty` = false player.volume > 0 According the value above, it seems not cause by empty playback buffer or volume issue. I am so confused for this situation. Movie information Video Format : AVC Format/Info : Advanced Video Codec Format profile : High L5.1 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Bit rate mode : Variable Bit rate : 100.0 Mb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 29.970 (30000/1001) FPS Audio Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : mp4a-40-2 Duration : 5 min 19 s Bit rate mode : Constant Bit rate : 192 kb/s Nominal bit rate : 48.0 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF) Does anyone know if AVPlayer has this limitations when playing high-bitrate movie streams, and are there any solutions?

When using the built-in macOS screen recording feature, the recording stops automatically after approximately 10–15 minutes without any warning or error message. No manual stop action is performed. The recording simply ends silently. The same issue also occurs when using ScreenCaptureKit in a custom application, which suggests this may be a system-level issue related to screen capture rather than an app-specific problem. This issue is reproducible and happens consistently after running for a period of time.
