The media services used for HLS streaming in an AVPlayer seem to crash if your segments are too large. Anything over 20Mbps seems to cause a crash. I have tried adjusting the segment length to 1 second also and it didn't help. I am remuxing Dolby Vision and HDR video and want to avoid transcoding and losing any metadata. However the segments are too large. Is there a workaround for this? Otherwise it seems AVFoundation is not suited to high bitrate HLS and I should be using MPV or similar.

Hello, we have HLS stream app and we use AVPlayer for HLS stream. We want to implement dynamic resulotion feature as user's selection. For example, if user want to watch only 1080p user has to watch only 1080p but we have tried to implement "preferredMaximumResolution" and "preferredPeakBitRate" parameters and but AVPlayer does not force it which means that setting preferredMaximumResolution= CGSize(width: 1920, height: 1080) player does not only force to play 1080p profile, player drops resulotion to 720p but we do not want 720p stream if user selected 1080p resulotion. Is there any method to force it even if stream stalls? Thank you in advance

Observing 4K playback issues on tvOS 18. Encountering HTTP 416 (Range Not Satisfiable) errors when the player attempts to request byte ranges that are outside the available data on the server. This leads to fatal playback error resulting in the error CoreMediaErrorDomain error -12939 - HTTP 416: Requested Range Not Satisfiable Notably, there are no customizations or modifications to the standard AVPlayerViewController on tvOS player. AVPlayer is trying to request the resource of length equals 739 bytes with an invalid byte range (739-) request. Since the request is not satisfiable server returns with 416. Note this is only limited to tvOS 18 and we are trying to understand why AVPlayer is making this invalid request in tvOS 18 resulting in playback error.

Hi, I am trying to stream spatial video in realtime from my iPhone 16. I am able to record spatial video as a file output using: let videoDeviceOutput = AVCaptureMovieFileOutput() However, when I try to grab the raw sample buffer, it doesn't include any spatial information: let captureOutput = AVCaptureVideoDataOutput() //when init camera session.addOutput(captureOutput) captureOutput.setSampleBufferDelegate(self, queue: sessionQueue) //finally func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) { //use sample buffer (but no spatial data available here) } Is this how it's supposed to work or maybe I am missing something? this video: https://developer.apple.com/videos/play/wwdc2023/10071 gives us a clue towards setting up spatial streaming and I've got the backend all ready for 3D HLS streaming. Now I am only stuck at how to send the video stream to my server.

I use AVPlayer to play HLS video successfully on macOS Sonoma, but I encountered this error on macOS Sequoia. Please help me: Error Domain=AVFoundationErrorDomain Code=-11833 ‘Cannot Decode’ UserInfo={NSUnderlyingError=0x600001e57330 {Error Domain=CoreMediaErrorDomain Code=-12906 ‘(null)’}, NSLocalizedFailureReason=The decoder required for this media cannot be found., AVErrorMediaTypeKey=vide, NSLocalizedDescription=Cannot Decode} Thanks!

The same H265 encrypted Fairplay content can be played in all Apple devices except A1625. The clear H265 content is played in A1625. The question is: will this model (A1625) support H265 Fairplay encrypted content? A ticket was created here: https://discussions.apple.com/thread/255658006?sortBy=best

When playing several short HLS clips using AVPlayer connected to a TV using Apple's Lightning-to-HDMI adapter (A1438) we often fail with those unknown errors. CoreMediaErrorDomain -12034 and CoreMediaErrorDomain -12158 Anyone has any clue what the errors mean? Environment: iPhone8 iOS 15.4 Lightning-to-HDMI adapter (A1438)

Hi,It seems like it's pretty easy to consume HTTP Live Streaming content in an iOS app. Unfortunately, I need to consume media from an RTSP server. It seems to me that this is a very similar thing, and that all of the underpinnings for doing it ought to be present in iOS, but I'm having a devil of a time figuring out how to make it work without doing a lot of programming.For starters, I know that there are web-based services that can consume an RTSP stream and rebroadcast it as an HTTP Live Stream that can be easily consumed by the media players in iOS. This won't work for me because my application needs to function in an environment where there is no internet access (it's on a private Wifi network where the only other thing on the network is the device that is serving the RTSP stream).Having read everything I can get my hands on and exploring third-party and open-source solutions, I've compiled the following list of ideas:1. Using an iOS build of the open-source ffmpeg library, which supports RTSP, I've come up with a test app that can receive the RTSP packets, decode them, create UIImages out of the frames, and display those frames on-screen. This provides a crude player, but performance is poor, most likely because ffmpeg can't take advantage of any hardware acceleration. It also doesn't provide me with any way to integrate the video stream into AVFoundation, so I'm on my own as far as saving the stream to a file, transcoding it, etc.2. I know that the AVURLAsset class doesn't directly support the RTSP scheme. Since I have access to the undecoded RTSP packets via ffmpeg, I've thought it should be possible to implement RTSP support myself via a custom NSURLProtocol, essentially fooling AVFoundation into reading those packets as if they originated in a file. I'm not sure if this would work, since the raw packets coming from the RTSP server might lack the headers that would otherwise be present in data being read from a file. I'm not even sure if AVFoundation would recognize my custom protocol.3. If a protocol doesn't work, I've considered that I might be able to implement my own local HTTP Live Streaming server that converts the RTSP packets into an HTTP stream that the media players can read. This sounds like a terribly convoluted solution to the problem, at best, and very difficult at worst.4. Going back to solution (1), if I could speed up the decoding by using some iOS CoreVideo function instead of ffmpeg, this solution might be okay. However, I can't find any documentation for CoreVideo on iOS (Apple only documents it for OS X).5. I'm certainly willing to license a third-party solution if it works well and provides good performance. Unfortunately, everything I've found so far is pretty crummy and mostly just leverages ffmpeg and/or VLC. What is most disappointing to me is that nobody seems to be able or willing to provide a solution that neatly integrates with AVFoundation. I really want to make my RTSP stream available as an AVAsset so I can use it with AVFoundation players and other classes -- I don't want to build an app that relies on custom third-party code for everything.Any ideas, tips, advice would be greatly appreciated.Thanks,Frank
