Hello I have a HLS manifest with multiple audio and multiple subtitle tracks. I use AVPlayer on iOS to play this HLS asset. On the iOS app I have the freedom to display selective subtitle and audio track list to the user but when the user uses AirPlay on the iOS, all the subtitle and audio tracks available in the HLS manifest is displayed to the user on the Apple TV (or any AirPlay compatible device). Let me explain with one example. Say, the HLS manifest has the following tracks: English, Spanish & German audio tracks English, Italian, Spanish & German subtitle tracks When the user uses AirPlay, I want to hide German language and display only the following tracks on the Apple TV: English & Spanish audio tracks English, Italian & Spanish subtitle tracks The primary intent here is that the user should not be able to see German language anywhere on the target AirPlay device. How to achieve this in code? Note: It's difficult to modify the source HLS manifest file.

Hi,Refering to the "FairPlay Streaming Certificate Generation Guide"On page 7, we have created newreq.inf file and generated certreq.csr However, we didn't apply "certreq -accept newcert.pem"Then, we continue to create FPS Certificate by uploading our certreq.csr.We received the ASk and fairplay.cerWill this be a problem?Is there anyway we can amend the private key? Or do we need to resubmit FPS Deployment package to redo the process?Thanks.

I have an iOS app that can play audio books as FairPlay DRM'd audio streams. I'm using AVContentKeySession to fetch keys and AVQueuePlayer to play. It works great on iOS, but on Catalyst (Monterey 12.3.1, M1 Max MacBook Pro) it crashes. When it happens in debug, I get a message "Too few bits left in input buffer" printed to the console, and an exception is thrown in the guts of what appears to be core media. Here's the output from [NSThread callStackSymbols] when paused on an exception breakpoint at that point: 0   ???                       0x0000000156b8cc9c 0x0 + 5749918876, 1   BRFree                    0x000000010445cf08 main + 0, 2   AudioCodecs               0x0000000157918c24 _ZL11GetPropertyPvjPjS_ + 52, 3   AudioToolboxCore          0x00000001862536a4 _ZN15ADTSAudioStream11ParseHeaderER27AudioFileStreamContinuation + 1060, 4   AudioToolboxCore          0x000000018624259c AudioFileStreamParseBytes + 412, 5   MediaToolbox              0x00000001915f7d98 FigManifoldCreateForICY + 2176, 6   MediaToolbox              0x00000001915f7718 FigManifoldCreateForICY + 512, 7   MediaToolbox              0x00000001916bbd78 FigPlayerStreamCreate + 315920, 8   MediaToolbox              0x0000000191a269a0 FigMetadataConverterCreateForQuickTimeToFromiTunes + 45888, 9   MediaToolbox              0x0000000191a4a290 FigMetadataConverterCreateForQuickTimeToFromiTunes + 191536, 10  MediaToolbox              0x0000000191a2a470 FigMetadataConverterCreateForQuickTimeToFromiTunes + 60944, 11  MediaToolbox              0x0000000191a28c34 FigMetadataConverterCreateForQuickTimeToFromiTunes + 54740, 12  MediaToolbox              0x0000000191a413b4 FigMetadataConverterCreateForQuickTimeToFromiTunes + 154964, 13  MediaToolbox              0x0000000191a2f144 FigMetadataConverterCreateForQuickTimeToFromiTunes + 80612, 14  MediaToolbox              0x00000001917cae64 FigAlternateFilterMonitorCreateForThermalNotification + 30428, 15  MediaToolbox              0x00000001917ccb44 FigAlternateFilterMonitorCreateForThermalNotification + 37820, 16  MediaToolbox              0x00000001917cb134 FigAlternateFilterMonitorCreateForThermalNotification + 31148, 17  CFNetwork                 0x0000000189937cd4 _CFHostIsDomainTopLevelForCertificatePolicy + 27728, 18  Foundation                0x0000000185ba980c __NSBLOCKOPERATION_IS_CALLING_OUT_TO_A_BLOCK__ + 24, 19  Foundation                0x0000000185ba96b4 -[NSBlockOperation main] + 104, 20  Foundation                0x0000000185ba9644 __NSOPERATION_IS_INVOKING_MAIN__ + 24, 21  Foundation                0x0000000185ba88dc -[NSOperation start] + 788, 22  Foundation                0x0000000185ba85c0 __NSOPERATIONQUEUE_IS_STARTING_AN_OPERATION__ + 24, 23  Foundation                0x0000000185ba8478 __NSOQSchedule_f + 184, 24  libdispatch.dylib         0x00000001099f60f4 _dispatch_block_async_invoke2 + 148, 25  libdispatch.dylib         0x00000001099e2394 _dispatch_client_callout + 20, 26  libdispatch.dylib         0x00000001099eb778 _dispatch_lane_serial_drain + 980, 27  libdispatch.dylib         0x00000001099ec814 _dispatch_lane_invoke + 492, 28  libdispatch.dylib         0x00000001099f9fc8 _dispatch_root_queue_drain + 408, 29  libdispatch.dylib         0x00000001099f9d3c _dispatch_worker_thread + 264, 30  libsystem_pthread.dylib   0x00000001094e1890 _pthread_start + 148, 31  libsystem_pthread.dylib   0x00000001094ebaa8 thread_start + 8 In the Debug Navigator, the top of the stack looks a little different: #0 0x0000000184bdeb3c in __cxa_throw () #1 0x000000015791941c in ACMP4AACLowComplexityDecoder::GetProperty(unsigned int, unsigned int&, void*) () #2 0x0000000157918c24 in GetProperty(void*, unsigned int, unsigned int*, void*) () #3 0x00000001862536a4 in ADTSAudioStream::ParseHeader(AudioFileStreamContinuation&) () #4 0x000000018624259c in AudioFileStreamParseBytes () #5 0x00000001915f7d98 in ___lldb_unnamed_symbol598$$MediaToolbox () What's going wrong here?

When I tested it, mp4 container subtitles cannot be played (VTT can be played). mp4 subtitles AVFoundation doesn't support mp4 subtitles?

Website serving Apple FairPlay videos here... I have three users reporting problems with playback using Safari on iPad with iOS 15.4. It seems they can no longer use Chrome (where we serve the same videos using DASH+CENC) either. That is all I know at this time. Not finding anything from google except the 15.1 FairPlay debacle... Just fishing. Anything similar for anyone else? Thank you kindly.

Hello everyone, I have downloaded the SDK 4.4.1 from Apple and I'm trying to implement fairplay streaming with encrypted videos. I have arrived the a section whereby it is asking to test Key Security Modules. I cannot get hold of any pkeyPem variable with a value and also cannot find the spc_internal_values_v2.txt file. Can anyone help me out? Thank you very much!

Hi All,I'm testing the KSM implementation in the spc_internal_values_v2.txt file provided by the sdk we have spc payload data,but the ksm needs the entire spc container message to process the request(including the version, IV, key and certificate hash).is there a way to test the implementation?Thanks in advance

Hi, I have a video streaming application and a part of code which use FairPlay + DRM. Im trying stream DRN content on appletv and It works well on iOS 13, but on iOS 15 i see nothing and catch internal player error: Error Domain=AVFoundationErrorDomain Code=-11870 "Operation failed" UserInfo={NSLocalizedFailureReason=An unknown error has occurred (808), NSLocalizedDescription=Operation failed, NSUnderlyingError=0x283902700 {Error Domain=NSOSStatusErrorDomain Code=808 "(null)"}}

I've been maintaining adaptive HLS+FairPlay streams with audio and video for years. My implementation works great. However, I'm now also implementing captions or subtitles, and I'm having trouble with the later. I'm actually able to generate my HLS streams with WebVTT subtitles, and they work great. But as soon as I encrypt the streams, Apple players stop working (forever stall). And my fairplay implementation works perfectly when no subtitles are involved. I'm not encrypting the webvtt chunks: they travel as plain text, as stated in Apple guidelines. I believe this may be the issue: encrypted a/v streams with an unencrypted subtitles stream. However, encrypting plain text subtitles with SAMPLE-AES has no sense to me, so far I was unable to find a single HLS example online with subtitles that also happen to have FairPlay encryption. All documents I have about FairPlay also say nothing about this, I've also tried applying CEA-608 closed captions in the video stream, and this actually works great with FairPlay. But CEA-608 has its own issues, and so I would like to migrate that tech to WebVTT: which also works great, except when FairPlay is involved. I understand that Apple also establishes that I could use TTML (ISMC1) inside fMP4, which I suspect may be SAMPLE-AES encryptable. However, given my customers use cases, I need to use TS format for HLS, and so I can't use fMP4. With all this in mind, do anybody know how to properly configure HLS+FairPlay with a plain text WebVTT subtitles stream? Please note this is about live streaming, and not VOD nor offline playback. Thanks.

Hi I wish to know where I can find documentation / sdk to user widevine and / or Fairplay in our application. Is there any examples of using it in AVPlayer? Thank you very much for any help.

Trying to download an encrypted HLS stream we faced the following issue: When we start a new download, calling resume() function of AVAssetDownloadTask, the download process gets stuck (not every time) and neither of urlSession(_:assetDownloadTask:didFinishDownloadingTo:) or urlSession(_:task:didCompleteWithError:) delegate functions (AVAssetDownloadDelegate) are getting called. There are cases where not even the urlSession(_:assetDownloadTask:didLoad:totalTimeRangesLoaded:timeRangeExpectedToLoad:) delegate function is getting called. Any suggestions on how to troubleshoot?

When recording 4K 60fps on iPhone 11 Pro, 12 and 13 it does not provide a stable frame rate of 60fps. Checking the Meta data it ranges from 52-58. Are there any settings that can force 60 frames or anything I can do to get a stable frame rate of 60fps. it also appears when trimming the video the frame rate drops as well.

Hi, IOS 15 Safari does not support Fairplay DRM and gives an error, other browsers like Chrome also do not work. Since IOS 15 released today, we as DRM providers are having a lot of complaints from our customers. The issue does not happen on IOS app, only for IOS browser. We have seen the same issue across multiple DRM providers, so issue is at the end of Apple and only occurs for IOS 15.

I recently successfully registered for the FPS certificate but I lost the ASK. How can I find it? Or I need to revoke the certificate.

I am encoding CMAF contents and when I try to stream a DRM'd video on Safari, nothing happens and I don't even have an error code. It is working without any problem on Chrome (widevine). Our partners can stream the content on their side but we can't, on Macbook or iPhone... We have tested CMAF on the following iOS versions on various device types (phones and tablets): .3 .1 .1 .1 • 14 • 14.3 It was working without any problem. We had an issue on: Macbook pro M1 - Big Sur 11.3.1 Safari Version 14.1 (16611.1.21.161.6) iPhone 12.- iOS 14.5.1 Iphone 12. - iOS 14.4.2 Macbook Air Intel 2020 - Big Sur 11.2.3 Sometimes, it is working when I reload the page ... I don't know what happens...

Hi, we have a customer having problem with our TV Live application with its iPhone 13 iOS 15. The player raises a CoreMediaErrorDomain error -42765 upon fairplay HLS stream. Is it possible to get a description and potential cause of this probleme to help him. Kind regards Cédric

Playbacking FPS content on iOS v15 Beta + Safari fails even if key request succeeds. I've used Shaka player and other HTML5 players which ends in the same result. Although, when trying it on AVPlayer, playback succeeds so I guess there is some problem in Safari or somewhere. Is it a bug and will it be fixed before release? By the way iOS v14 + Safari + FPS works with no problem.

Hello!Well, I am trying to get the apple fairplay demo working for safari.My manifest#EXT-X-SESSION-KEY:METHOD=AES-128,URI="XXXXXXXXX"#EXT-X-STREAM-INF:BANDWIDTH=53000,CODECS="mp4a.40.5"hls-audio=49152.m3u8And I have a method waiting for the event webkitneedkey but it is not being called. video.addEventListener('webkitneedkey', onneedkey, false);Why? What is the problem?

I am running a spike for apple watches and one of the things that I'm evaluating now is the capability to play HLS + fairplay content offline. It seems like the only way forward is by using AVAssetDownloadTask, which is not available on watchOS. So, my question is if there is any plan to release this capability to apple watches soon or if there is any other way to do that.

Hi all~!I got an error code -66681 when AVPlayer starts playing, after I updated iOS version to 13.4.When I checked it on osstatus.com, it named 'kAudioQueueErr_CannotStart' from AudioToolBox.framwork.However I have no any clue what it means.Order versions have no issue. It works perfectly.FYI, I set signed cookies to AVURLAsset and it works with non-drm videos.let cookies = cookieInfo.map { HTTPCookie.cookies(withResponseHeaderFields: ["Set-Cookie": "\($0.key)=\($0.value)"], for: url) }.flatMap { $0 } asset = AVURLAsset(url: url, options: [AVURLAssetHTTPCookiesKey : cookies])Issue occures with only drm videos.Could anybody give me some advice about this?
