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.

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.

Hi there, I want to play a stream of audio immediately after the first chunk of the audio arrives. The data stream looks like this Audio_data, Delimiter, Json_data. currently I am handling all chunks before the delimiter and adds it in the queue of the AVQueuePlayer. However, when playing this audio during the stream there are many glitches and does not work well. Waiting until all chunks arrived and then play the audio works well. So I assume there is no problem with the audio data, but with the handling of the chunks as they come and play immediately. Happy about any advice you have! I am pretty lost right now. Thank you so much. import SwiftUI import AVFoundation struct AudioStreamView: View { @State private var players: [AVAudioPlayer] = [] @State private var jsonString: String = "" @State private var queuePlayer = AVQueuePlayer() var streamDelegate = AudioStreamDelegate() var body: some View { VStack(spacing: 20) { Button("Fetch Stream") { fetchDataFromServer() } .padding() TextEditor(text: $jsonString) .disabled(true) .border(Color.gray) .padding() .frame(minHeight: 200, maxHeight: .infinity) } } func fetchDataFromServer() { guard let url = URL(string: "https://dev-sonia.riks0trv4c6ns.us-east-1.cs.amazonlightsail.com/voiceMessage") else { return } var request = URLRequest(url: url) request.httpMethod = "POST" // Specify the request type as POST let parameters: [String: Any] = [ "message_uuid": "value1", "user_uuid": "68953DFC-B9EA-4391-9F32-0B36A34ECF56", "session_uuid": "value3", "timestamp": "value4", "voice_message": "Whats up?" ] request.httpBody = try?

On the FairPlay main page it states: The FPS Deployment Package is not available to third parties acting on behalf of licensed content owners. Could someone please provide more details around this statement? If I were to build a subscription based platform where users can upload & monetize their videos, and used FairPlay to prevent unauthorized access to the creator's content, what would Apple's response be?

It's been over a month since I requested an FPS Deployment Package, and the only response I've gotten is a case number and an email stating that a representative will check in and get back to me, usually on Wednesday. I'm wondering if I need to do anything further or if cases like mine are common.

In our application, we play video-on-demand (VOD) content and display subtitles in different languages.

Hello, I am interested in developing an iOS app that can monitor and potentially block third-party applications while a specific app is running. I would like to inquire about the feasibility of implementing such functionality within the iOS ecosystem and if there are any privacy terms or restrictions that I need to be aware of to ensure compliance with Apple's policies. Thank you for your guidance.

Case-ID: 3540728, we have developer membership, we have applied for fps on 31st July, and it was acknowledged from apple end, it was expected to be done in a week, although despite of many reminders we still have not got any response from apple reviewing team. can anyone have idea about why its taking so long. any help is appreciated.

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

Hi, we have hls+fps stream, on our app implementation through AVAssetResourceLoader (get spc, generate ckc correctly) and stream played successfully But when we try to download stream for offline, through session.processContentKeyRequest for contentId, we get spc, generate ckc the same as previously, but can't recieve persistent key data keyRequest.persistableContentKey PKD failed Error Domain=AVFoundationErrorDomain Code=-11835 "Cannot Open" UserInfo={NSLocalizedFailureReason=This content is not authorized., NSLocalizedDescription=Cannot Open, NSUnderlyingError=0x282da98f0 {Error Domain=NSOSStatusErrorDomain Code=-42668 "(null)"}} Server and client the same, fps stream played, but not load pkd for offline All offline part of sources we get from HLS Catalog example, and implement requestCertificate and requestContentKeyFromKeySecurityModule, and i don't understand why we not recieve pkd.

When i validated the VOD playlist with media stream validator, am getting the "Different target durations detected" error for trk vs sub, var vs sub playlists, Error: Different target durations detected --> Detail: Target duration: 3599 vs Target duration: 6 --> Source: subs/eus_2/playlist.m3u8 --> Compare: trk969287/playlist.m3u8 --> Detail: Target duration: 6 vs Target duration: 3599 --> Source: var969287/playlist.m3u8 --> Compare: subs/eus_2/playlist.m3u8 but the apple specification (https://developer.apple.com/documentation/http-live-streaming/hls-authoring-specification-for-apple-devices specification) stated that "5.7. For VOD content, target durations of subtitle playlists MAY be longer than the other media." Can you please clarify the query that why we are getting different target duration error for subtitle vs other media playlists even though the apple spec mentioned that the subtitle playlist may be longer than other media for VOD assets?

I need to correctly determine the mime type of keynote file and numbers file without relying on the extension. For this purpose, I am hoping to use the magic number concept and match it with the first four bytes of a file. Link for magic number understanding -> [https://www.outsystems.com/forge/component-overview/10108/validate-file-extension#:~:text=A%20magic%20number%20is%20a,types%20which%20is%20hexadecimal%20format.] Though after extensive searching online I am unable to find a unique magic number for the above files moreover first four bytes of the file is matching with the magic number of the zip file due to which I am getting the wrong extension as zip. This is the first four bytes 0x50, 0x4B, 0x3, 0x4. Is there any reliable way to find the mime type of these files without relying on an extension?

We have created a hls playback framework and lot of our client's are complaining about this error {"code": -19152, "domain": "CoreMediaErrorDomain", "localizedDescription": "The operation couldn’t be completed. (CoreMediaErrorDomain error -19152 - The operation couldn’t be completed. (CoreMediaErrorDomain error -19152.))", "localizedFailureReason": "", "localizedRecoverySuggestion": ""} We are unable to reproduce this issue on our end but we have data reflecting the same error happening at good rate. Any help/hint is welcome. Thanks
