Hi Team, We see an issue with this version if CoreMedia requesting multiple qualities at all times for a stream. We don't see this issue on 1.0.0.21C62. We are unsure what would be causing this.

I'm trying to use AVCaptureSession and AVAssetWriter to convert video and audio from an iPhone's camera and microphone into a fragmented video file in AppleHLS format. Below is part of the code. It seems that the capture is successful, and I have confirmed that the data received with captureOutput() can be appended to videoWriterIput and audioWriterInput using append(). When executing audioWriterInput!.append(sampleBuffer), sampleBuffer has the following value, and it looks like the audio data has been passed to AssetWriter. sampleBuffer.duration : CMTime(value: 941, timescale: 44100, flags: __C.CMTimeFlags(rawValue: 1), epoch: 0) sampleBuffer.totalSampleSize : 1882 However, the final output init.mp4 and *.m4s do not contain Audio.

We have to play some encrypted videos from server. In AVAssetResourceLoaderDelegate we got the ckc data correctly and responded with that. Then video just starts playing and stops immdediately. When we check the playerItem error description we got Error Domain=AVFoundationErrorDomain Code=-11819 "Cannot Complete Action" UserInfo={NSLocalizedDescription=Cannot Complete Action, NSLocalizedRecoverySuggestion=Try again later.}. Any one encountered this?

I am trying to set up HLS with MV HEVC. I have an MV HEVC MP4 converted with AVAssetWriter that plays as a "spatial video" in Photos in the simulator. I've used ffmpeg to fragment the video for HLS (sample m3u8 file below). The HLS of the mp4 plays on a VideoMaterial with an AVPlayer in the simulator, but it is hard to determine if the streamed video is stereo. Is there any guidance on confirming that the streamed mp4 video is properly being read as stereo? Additionally, I see that REQ-VIDEO-LAYOUT is required for multivariant HLS. However if there is ONLY stereo video in the playlist is it needed? Are there any other configurations need to make the device read as stereo? Sample m3u8 playlist #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:13 #EXT-X-MEDIA-SEQUENCE:0 #EXTINF:12.512500, sample_video0.ts #EXTINF:8.341667, sample_video1.ts #EXTINF:12.512500, sample_video2.ts #EXTINF:8.341667, sample_video3.ts #EXTINF:8.341667, sample_video4.ts #EXTINF:12.433222, sample_video5.ts #EXT-X-ENDLIST

Hi Apple Team, we are observing following error intermittently when trying to playback FairPlay protected HLS streams. The error happens immediately after loading the certificate. Playback with same certificate on same device(Mac, iPhone) works most of time but intermittently this error is observed with following codes. The code=6 means MEDIA_KEYERR_DOMAIN but I did not find any information on what does systemCode=4294955417 mean? Is there a way to check what does this system code mean and what could be causing this intermittent behaviour? { "code": 6, "systemCode": 4294955417 }

Can we confirm that as of iOS 16.3.1, key frames for MPEGTS via HLS are mandatory now? I've been trying to figure out why https://chaney-field3.click2stream.com/ shows "Playback Error" across Safari, Chrome, Firefox, etc.. I ran the diagnostics against one of the m3u8 files that is generated via Developer Tools (e.g. mediastreamvalidator "https://e1-na7.angelcam.com/cameras/102610/streams/hls/playlist.m3u8?token=" and then hlsreport validation_data.json) and see this particular error: Video segments MUST start with an IDR frame Variant #1, IDR missing on 3 of 3 Does Safari and iOS devices explicitly block playback when it doesn't find one? From what I understand AngelCam simply acts as a passthrough for the video/audio packets and does no transcoding but converts the RTSP packets into HLS for web browsers But IP cameras are constantly streaming their data and a user connecting to the site may be receiving the video between key frames, so it would likely violate this expectation. From my investigation it also seems like this problem also started happening in iOS 16.3? I'm seeing similar reports for other IP cameras here: https://ipcamtalk.com/threads/blue-iris-ui3.23528/page-194#post-754082 https://www.reddit.com/r/BlueIris/comments/1255d78/ios_164_breaks_ui3_video_decode/ For what it's worth, when I re-encoded the MPEG ts files (e.g. ffmpeg-i /tmp/streaming-master-m4-na3.bad/segment-375.ts -c:v h264 /tmp/segment-375.ts) it strips the non key frames in the beginning and then playback works properly if I host the same images on a static site and have the iOS device connect to it. It seems like Chrome, Firefox, VLC, and ffmpeg are much more forgiving on missing key frames. I'm wondering what the reason for enforcing this requirement? And can I confirm it's been a recent change?

We're experimenting with a stream that has a large (10 minutes) clear portion in front of the protected section w/Fairplay. We're noticing that AVPlayer/Safari trigger calls to fetch the license key even while it's playing the clear part, and once we provide the key, playback fails with: name = AVPlayerItemFailedToPlayToEndTimeNotification, object = Optional(<AVPlayerItem: 0x281ff2800> I/NMU [No ID]), userInfo = Optional([AnyHashable("AVPlayerItemFailedToPlayToEndTimeErrorKey"): Error Domain=CoreMediaErrorDomain Code=-12894 "(null)"]) - name : "AVPlayerItemFailedToPlayToEndTimeNotification" - object : <AVPlayerItem: 0x281ff2800> I/NMU [No ID] ▿ userInfo : 1 element ▿ 0 : 2 elements ▿ key : AnyHashable("AVPlayerItemFailedToPlayToEndTimeErrorKey") - value : "AVPlayerItemFailedToPlayToEndTimeErrorKey" - value : Error Domain=CoreMediaErrorDomain Code=-12894 "(null)" It seems like AVPlayer is trying to decrypt the clear portion of the stream...and I'm wondering if it's because we've set up our manifest incorrectly. Here it is: #EXTM3U #EXT-X-VERSION:8 #EXT-X-TARGETDURATION:20 #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-PLAYLIST-TYPE:VOD #EXT-X-MAP:URI="clear-asset.mp4",BYTERANGE="885@0" #EXT-X-DEFINE:NAME="path0",VALUE="clear-asset.mp4" #EXTINF:9.98458, #EXT-X-BYTERANGE:81088@885 {$path0} #EXTINF:19.96916, #EXT-X-BYTERANGE:159892@81973 {$path0} #EXTINF:19.96916, #EXT-X-BYTERANGE:160245@241865 {$path0} #EXT-X-DISCONTINUITY #EXT-X-MAP:URI="secure-asset.mp4",BYTERANGE="788@0" #EXT-X-DEFINE:NAME="path1",VALUE="secure-asset.mp4" #EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://guid",KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1" #EXTINF:19.96916, #EXT-X-BYTERANGE:159928@5196150 {$path1} #EXT-X-ENDLIST

Dear Apple Engineers, First of all, thank you for this wonderful and very necessary native solution. Question: Is it possible to use this API when processing HLS? Thank you.

Hi Team, Offline playback with AES-128 encryption I'm downloading HLS content that is AES-128 encrypted and using the AVAssetResourceLoaderDelegate method shouldWaitForLoadingOfRequestedResource to parse the manifest to fetch the AES key URL. After fetching the key URL, I'll download and save the AES key locally. I will use the locally saved key to start the offline playback. Since AVContentKeySession has been there for quite some time, is it okay to use the resource loader delegate method to parse and download the AES key? Is there any chance that Apple will deprecate the downloading keys through the resource loader delegate? Thanks, Deepak.N

Hello, I'm having an issue where my app is in TestFlight, and some of my testers are reporting that FairPlay protected videos are not playing back in iOS 17. It's been working fine in iOS 16 (my app's initial target). I can see from the debug logs that for an online stream request - contentKeySession(_ session: AVContentKeySession, didProvide keyRequest: AVContentKeyRequest) is never called. Whereas, a download for offline playback request, the function is called. I've used much of the sample code in "HLS Catalog With FPS" as part of the FPS developer package. All of my m3u8 files are version 5 and contain encryption instructions like below: #EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://some-uuid",KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1" Here's a short excerpt of the code being run: let values = HTTPCookie.requestHeaderFields(with: cookies) let cookieOptions = ["AVURLAssetHTTPHeaderFieldsKey": values] assetUrl = "del\(assetUrl)" clip!.assetUrl = AVURLAsset(url: URL(string: assetUrl)!, options: cookieOptions) clip!.assetUrl!.resourceLoader.setDelegate(self, queue: DispatchQueue.global(qos: .default)) ContentKeyManager.shared.contentKeySession.addContentKeyRecipient(clip!.assetUrl!) urlAssetObserver = self.observe(\.isPlayable, options: [.new, .initial]) { [weak self] (assetUrl, _) in guard let strongSelf = self else { return } strongSelf.playerItem = AVPlayerItem(asset: (self!.clip!.assetUrl)!) strongSelf.player.replaceCurrentItem(with: strongSelf.playerItem) } The error thrown is: Task .<8> finished with error [18,446,744,073,709,550,614] Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSLocalizedDescription=unsupported URL, NSErrorFailingURLStringKey=skd://some-uuid, NSErrorFailingURLKey=skd://some-uuid, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask .<8>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask .<8>, NSUnderlyingError=0x2839a7450 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}} Which I believe is being thrown from AVPlayerItem. Without the delegate, it appears to playback fine. However, I need the delegate (I think), since I'm appending some query params to each request for the segments. I have an observer on the playerItem, per the example project which is changing the status to .failed once he -1002 error is thrown. Please let me know if anything rings to mind to try, or if I can provide any additional info. Thanks in advance!

Could you please tell me why?

What version of draft-pantos-hls-rfc8216bis does Apple currently support?

i am using DRM content in my player. facing this error frequently . we used both licenseUrl ,certificateUrl and DRM token .Content is not playing getting this error .

I've been encountering a substantial increase in the following error log and am eager to find its root cause. The pattern of these logs emerge predominantly when attempting to play downloaded FPS DRM files(MOVPKG files). Except for a few rare instances, most occurrences are associated with content downloaded in previous OS versions, leading to playback issues following recent OS updates. The error log I've been encountering is as follows: Error Domain=CoreMediaErrorDomain Code=-16845 "HTTP 400: (unhandled)" Even after searching, there are hardly any cases available, and the only thing I found is these issues https://github.com/jhomlala/betterplayer/issues?q=is%3Aissue+16845+is%3Aclosed I've been advising users to delete and re-download the affected content, which, in all cases, results in successful playback. I'm seeking advice from anyone who might have experienced similar issues. If you've encountered a comparable situation or have any suggestions, I would greatly appreciate your input.

My project is a TV player app for HLS streams with fairplay encryption. It is made on swiftUI for iPhone and iPad, it is in production. I have enabled the target "Mac (Designed for iPad)" in the project settings, and It is working perfectly on Mac M1 chips when running the app from the Mac AppStore. The Mac version has never been main main focus, but it is nice to have it working so easily. However when I run the app from Xcode, by selecting "My Mac (Designed for iPad)", everytime AVPlayer wants to start playback I am ejected from the app and the only thing I get from the logcat is: Message from debugger: Terminated due to signal 9 Why? And Why does it work when running the app published on the appstore? I was able to debug a bit and identify which line of code triggers the issue but I am still stuck: I am using an AVAssetResourceLoaderDelegate to load the Fairplay Keys instead of the default one (because I need some authentication parameters in the HTTP headers to communicate with the DRM Proxy). So, in the process I am able to request SPC data and CKC (I have verified the data), and then when the loadingRequest.finishLoading() is called.. BOOM the app is terminated and it triggers the log Message from debugger: Terminated due to signal 9. I am sharing the delegate method from the AVAssetResourceLoaderDelegate where it happens. This has been written a while ago and is running fine on all devices. If you are not used to this delegate, it is used by AVPlayer whenever a new mediaItem is set with the method: AVPlayer.replaceCurrentItem(with: mediaItem) func resourceLoader(_ resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool { guard let dataRequest = loadingRequest.dataRequest else { return false } getFairplaycertificate { data, _ in // Request Server Playback Context (SPC) data guard let certificate = data, let contentIdData = (loadingRequest.request.url?.host ?? "").data(using: String.Encoding.utf8), let spcData = try? loadingRequest.streamingContentKeyRequestData( forApp: certificate, contentIdentifier: contentIdData, options: [AVContentKeyRequestProtocolVersionsKey: [1]] ) else { loadingRequest.finishLoading(with: NSError(domain: "tvplayer", code: -1, userInfo: nil)) print("⚠️", #function, "Unable to get SPC data.") return false } // Now the CKC can be requested let networkId = loadingRequest.request.url?.host ?? "" self.requestCKC(spcData: spcData, contentId: networkId) { ckc, error in if error == nil && ckc != nil { // The CKC is correctly returned and is sent to AVPlayer. Stream is decrypted dataRequest.respond(with: ckc!) loadingRequest.contentInformationRequest?.contentType = AVStreamingKeyDeliveryContentKeyType loadingRequest.finishLoading() // <--- THIS LINE IS GUILTY!!! } else { print("⚠️", #function, "Unable to get CKC.") loadingRequest.finishLoading(with: error) } } return true } return true } If I comment loadingRequest.finishLoading() or if I replace it by: loadingRequest.finishLoading(with: error), the app is not terminated but my decryption keys are not loaded. That's the only clue I have so far. Any help would be appreciated. What should I look for? Is there a way to get a detailed error stacktrace? Thanks.

How to recognize #EXT-OATCLS-SCTE35 tag in live HLS playlist and also manifest has other custom tags. I have tried using timedMetadata property of AVPlayerItem , KVO approach. But it's not notifying the presence of this tag. Can someone help me in implementing this?

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!

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.
