While setting up our premium video-on-demand workflow in AWS, using AWS MediaConvert and MediaPackager and licence delivery from drmToday we encountered an issue with HLS+FairPlay playback (only) in Safari on macOS. The issue is that sometimes (more than 50% on the same video) the videoplayer initialization fails (with simple event of type=”error” in onerror callback). We are using Shaka player in our web application, so we first assumed that this (random) issue could be due to Shaka. However, we also tested with direct playback via the player and we observed the same issue, with same frequency. Since we have some content for which this problem does not occur and other content when the problem occurs very frequently, we tried to understand what could explain this difference. We noticed that for assets where the problem never occurs the order of the video submanifest was increasing, whereas for assets where the problem occurs frequently the order is decreasing. To isolate the issue we created a standalone page for a 2-minute asset and we are able to demonstrate that on this asset, when the bitrates are in decreasing order the playback with Safari on macOS fails more than 50% of the time. Test page using tag: KO: https://ntg-test-public-scr.s3.eu-west-1.amazonaws.com/aws-video.html OK: https://ntg-test-public-scr.s3.eu-west-1.amazonaws.com/aws-video.html?ok=1 Test page using Shaka: KO: https://ntg-test-public-scr.s3.eu-west-1.amazonaws.com/aws-shaka.html OK: https://ntg-test-public-scr.s3.eu-west-1.amazonaws.com/aws-shaka.html?ok=1 Notes: the issue is only reproducible with Safari on macOS (not with Safari on iOS) same HLS content + FairPlay plays OK 100% on tvOS the issue is only reproducible for HLS content with FairPlay (OK if no DRM)

We have created a hls playback framework and lot of our client's are complaining about this error The operation couldn’t be completed. (CoreMediaErrorDomain error -42716.)

Now I'm preparing LL-HLS demonstration by using HLS tools. Generated pattern and screen capture are okay. But input file option does not work. Please check whether it's possible to use explicit input file as source. In case of screen recording, the max resolution of multi variant manifest is FHD even though the display resolution is 3840x2160. Please check whether it's possible to set 4K UHD resolution.

Does anyone know if the toolset for HLS is still available, and if so, where to find it? I'm clicking links for downloads, but never find it: all I see are beta versions of OSs and some applications.

We utilized AVFragmentedAssetMinder to refresh the player data. While notifications for AVAssetDurationDidChange were consistently received whenever the player duration changed. However, following the release of iOS 17, notifications for AVAssetDurationDidChange ceased to be received. Could you please advise anyone why this notification is not being triggered? what we have to change NotificationCenter.default.addObserver(self, selector: #selector(self.onVideoUpdate), name: .AVAssetDurationDidChange, object: nil) #AVPLAyer, #AVMUtableMovie

Hi all, I am a graduate student who is looking into making MV-HEVC videos streamable. May I ask that is it possible to encode mv-hevc videos with the HLS (Http Live Streaming) protocol? I've been trying to use the HLS tool by Apple to encode a spatial video recored by VP. mediafilesegmenter -iso-fragmented -t 4 -f sp_video-1-vp spatial-video-by-vp.MOV But the output HLS playlist file doesn't look like the format that Apple proposes in the WWDC video. For example, the attribute EXT-X-VERSION is 7 instead of 12, and no attr REQ-VIDEO-LAYOUT=CH-STEREO which should be the key indicator of the spatial video type. From what the WWDC video showcased, I assume Apple's HLS tool supports it. Maybe my usage is not correct. Just curious what you guys think about it, thank you!

Hi, im new to swift development and i'm building ios version for my website chatpdf.so and i'm having trouble parsing server sent event from my server to the mobile app. Is there good library for swift to parse sse easily? I'm trying to implement it natively but im getting parsing error in EventSource.

Hi, This Apple provided program “SideBySideToMVHEVC” removes the audio track from our videos resulting in useless content. Advise for: code changes required permitting keeping the audio track Or advise for Apple tools permitting re-inserting the audio track after “SideBySideToMVHEVC” Sincerely, Olaf

I have a VisionOS app that streams 180VR video to create immersive experiences, similar to the Apple TV+ immersive content. These videos are 8k60fps. When looking at "video encoding requirements" (1.25) in the hls authoring specifications, there are only specifications for up to 4k30fps for MV-HEVC. Using the "power of .75 rule" I think that 160000kbps could be close to the 8k60fps recommendation. For launching my app, I did my best guess in creating the following multivariant playlist, with a generous low end and very generous high end, with 6 second segment durations for all variants. However, in practice, users seem to be to only be picking up the lower quality bandwidth content (80000kbps) even when speed tests are showing 5x that on the device. This leads to a lot artifacts in the content during playback, since its lower quality. If I hard code a higher bit rate variant (like 240000kbps) it does playback, but obviously has a bit more lag to start up. Now that I have my Vision Pro, I've been able to see the Apple TV+ immersive content. I could be wrong, but it doesn't feel like its varying playback - when watch by tethering to my phone vs on high speed wifi, the content looks the same just a little slower to load on the phone. I'm looking for 3 points of guidance: Are there hls recommendations for 8k60fps video? For both bitrates and target duration for the segments? Any guesses as to why I am not able to pick up the high bitrates? (this could simply be that the higher ends are still too high) While 180VR is just stereo video on a larger canvas, the viewing experience is quite different due to the immersion. Are there special recommendations for 180VR video? (Such as having only one variant and specified bitrate since a changing bitrate/video quality could be jarring to the viewer) Example HLS multivariant playlist: #EXTM3U #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=80632574,BANDWIDTH=82034658,VIDEO-RANGE=SDR,CODECS="mp4a.40.2,hvc1.1.60000000.L183.B0",RESOLUTION=4096x4096,FRAME-RATE=59.940,CLOSED-CAPTIONS=NONE https://myurl.com/stream/t4096p_080000_kbps_t6/prog_index.m3u8 #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=160782750,BANDWIDTH=162523567,VIDEO-RANGE=SDR,CODECS="mp4a.40.2,hvc1.1.60000000.L186.B0",RESOLUTION=4096x4096,FRAME-RATE=59.940,CLOSED-CAPTIONS=NONE https://myurl.com/stream/t4096p_160000_kbps_t6/prog_index.m3u8 #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=240941602,BANDWIDTH=243997537,VIDEO-RANGE=SDR,CODECS="mp4a.40.2,hvc1.1.60000000.L186.B0",RESOLUTION=4096x4096,FRAME-RATE=59.940,CLOSED-CAPTIONS=NONE https://myurl.com/stream/t4096p_240000_kbps_t6/prog_index.m3u8 #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=321061516,BANDWIDTH=325312545,VIDEO-RANGE=SDR,CODECS="mp4a.40.2,hvc1.1.60000000.H255.B0",RESOLUTION=4096x4096,FRAME-RATE=59.940,CLOSED-CAPTIONS=NONE https://myurl.com/stream/t4096p_320000_kbps_t6/prog_index.m3u8

I've encountered an issue with the seek bar time display in the video player on iOS 17, specifically affecting live stream videos using HLS manifests with the time displayed in am/pm format. As the video progresses, the displayed start time appears to shift backwards in time with a peculiar pattern: Displayed Start Time = Normal Start Time - Viewed Duration For instance, if a program begins at 9:00 AM, at 9:30 AM, the start time shown will erroneously be 8:30 AM. Similarly, at 9:40 AM, the displayed start time will be 8:20 AM. This issue is observed with both VideoPlayer and AVPlayerViewController on iOS 17. The same implementation of the video player on iOS 16 displays the duration of the viewed program and doesn’t have any issues. Please advise on any known workarounds or solutions to address this issue on iOS 17.

Hi hope all are well! We've been working on a live streaming app and it's going quite well! Just got the aspect ratio locked as desired. Now the audio, its volume is extremely low. It sounds like it's using the headset mic instead of the bottom mic that's used on Facetime or on speakerphone calls. We tried flipping cameras and specifying sample rates, almost every constraint in MediaConstraints - no go! Is there any way to specify this? Thanks in advance!

Mediastreamvalidiator error: all .m3u8 files relevant have already the REQ-VIDEO-LAYOUT="CH-STEREO" parameter set.

Dear Apple Engineers, I have downloaded the FairPlay Streaming SDK 4.4 - In which i could able to make use of the fps_safari_hls_example.html file to make a successful playback of fairplay protected content in safari, by pointing our fairplay license server, .m3u8 file & certificate. Now that, i'm trying to achieve the renewal concept, so i tried to use the fps_safari_hls_key_renewal.html file also setting up the ContentKeyDuration to 20sec in FP license server backend. But client didn't make any subsequent FP license request around when nearing 20th sec or post 20th sec. I wonder if this use case be achieved in safari, the only extra functionality i could see in renewal html file is below piece of code await runAndWaitForLicenseRequest(session, keyURI, () => { session.update(stringToUInt8Array("renew")) }); Based on the above piece, i assume that we are making sure that client to aware the when to renew the license. But in my case, there were no FP request is made , in-fact, this piece of code got executed immediate after the 1st FP license request call & protected media continues to play despite setting the ContentKeyDuration to 20sec with LIMITED as contentkeyType . Could you please suggest on how to achieve the subsequent renewal request from client based on the ContentKeyDuration send in the CKC response using this sample renewal html file..? Is there any tewaks to be made in html file, kindly suggest.

How Can I update the cookies of the previously set m3u8 video in AVPlayer without creating the new AVURLAsset and replacing the AVPlayer current Item with it

I play livestream thì bị lỗi : -12888 -"Playlist File unchanged for longer than 1.5 * target duration" , I also read error -12888 in the documentation page 170: https://docs.huihoo.com/apple/wwdc/ 2018/502_measuring_and_optimizing_hls_performance.pdf but still don't understand the reason. Please explain to me the reason for the error?

I am testing HLS Low latency streams but could not to a low playback latency. For comparison purpose I used Apple HLS-LL stream(https://ll-hls-test.cdn-apple.com/llhls4/ll-hls-test-04/multi.m3u8) where I can get latency of 6 seconds on Safari and AVPlayer. The main difference between the non-working and working streams is CAN-BLOCK-RELOAD attribute. This is set as YES for Apple HLS-LL test stream where latency is observed as 6 seconds vs other stream where latency is ~= 3 full segments duration(~18 seconds). As a test I tried to change CAN-BLOCK-RELOAD=YES to CAN-BLOCK-RELOAD=NO in variant playlist response of the Apple stream using a proxy tool after which I get same result of latency ~= 3 full segments duration(~18 seconds). On AVPlayer, I see following log with CAN-BLOCK-RELOAD=YES which seems to point towards AVPlayer entering low latency mode when setting up blocking reload. mediaserverd <SEGPUMP> segPumpSetupBlockingReload: 0x1040e7600: Player entering Low Latency mode Can Apple support or someone forum members who might have experience with this please share if CAN-BLOCK-RELOAD=YES is mandatory for low latency mode to be enabled in Safari browser and AVPlayer on iOS/tvOS?

HELP! How could I play a spatial video in my own vision pro app like the official app Photos? I've used API of AVKit to play a spatial video in XCode vision pro simulator with the guild of the official developer document, this video could be played but it seems different with what is played through app Photos. In Photos the edge of the video seems fuzzy but in my own app it has a clear edge. How could I play the spatial video in my own app with the effect like what is in Photos?

Hello, I keep getting this kind of errors (specifically 16247) when trying to download DRM-protected HLS content, would anyone have a clue about the reason why ?
