Hello, We're developing a video streaming service. Can't get the video to stream on AirPlay2-enabled TVs, there is only a loader visible on the tV. We can only get the sounds to stream to AirPlay2 speakers. Media Stream Validator and HLS report on the playlists, shows that the video segments are recognized as something but can't process them. "Processed 0 of 600 segments" etc. We're at a loss on how to debug this. Is there any way to get access to AirPlay 2 logs to see what isn't working?

Hello we are experiencing a quality drop when streaming via HTTP Live Streaming on iOS 15. The file behaves as expected on iOS 14 and 13. Is this a known issue? If so when can we expect a fix or is there a workaround?

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, I have an app that uses AVPlayer to stream and play videos (HLS) but I'm struggling to find a way to do the same with fmp4. This is what I use to play my HLS stream. I tried just to replace the url with the fmp4 one but it does not work. private func connect() {         let stringUrl = "https://wolverine.raywenderlich.com/content/ios/tutorials/video_streaming/foxVillage.m3u8"         let url = URL(string: stringUrl)!         let asset = AVURLAsset(url: url)         let item = AVPlayerItem(asset: asset)         if #available(iOS 10.0, *) {             item.preferredForwardBufferDuration = Double(50000) / 1000         }         if #available(iOS 13.0, *) {             item.automaticallyPreservesTimeOffsetFromLive = true         }         self.player = AVPlayer(playerItem: item)         let playerLayer = AVPlayerLayer(player: self.player)         playerLayer.frame = self.playerView.bounds         playerLayer.videoGravity = .resizeAspect         self.playerView.layer.addSublayer(playerLayer)         self.videoLayer = playerLayer         self.videoLayer?.frame = self.playerView.bounds         player?.play()     } I haven't got any luck looking for a possible solution and I'm out of ideas. I'll be really grateful if anyone of you could point me to a good direction.

We continuously are getting playback failed for live stream with error logs as: //Error 1 Segment exceeds specified bandwidth for variant||The operation couldn’t be completed. (CoreMediaErrorDomain error -12889.)|| //Error 2 The operation couldn’t be completed. (CoreMediaErrorDomain error -12888 - Playlist File unchanged for longer than 1.5 * target duration)|| //Error 3 Segment exceeds specified bandwidth for variant|| If we could actually find what -16042 error actually signifies, that would be great. P.S : We can provide any details regarding stream if required.

we are playing a HLS stream with the help of AV player and trying to read HLS manifest. We are able to detect majority of the tags however player is not detecting the EXT-X-DATERANGE:ID with DURATION tag ie #EXT-X-DATERANGE:ID="aba74c45-e963-45bf-8171-1f910c33f64a",DURATION=32.44 Where as, the other #EXT-X-DATERANGE:ID has been detected at the beginning of the manifest. #EXT-X-DATERANGE:ID="aba74c45-e963-45bf-8171-1f910c33f64a",START-DATE="2022-03-10T13:18:15.179Z",PLANNED-DURATION=15,X-AD-ID="9858" #EXT-X-DISCONTINUITY We are using the AVPlayers metadata collector delegate method to detect the metadata func metadataCollector(_ metadataCollector: AVPlayerItemMetadataCollector, didCollect metadataGroups: [AVDateRangeMetadataGroup], indexesOfNewGroups: IndexSet, indexesOfModifiedGroups: IndexSet) {} We are not able to detect the EXT-X-DATERANGE:ID with DURATION tag with the delegate used above Any help appreciated.

I would like to implement the OTT service with apple HLS playbackURL, I wonder what is the best practice for serving HLS streaming to the player whether Separated 2 endpoint between the playlist and segment(thus, playlist not cache at the middle layer even segment can be cached) or Use the same endpoint either playlist and segment, the playlist and segment will request to the same endpoint (playlist not cache at the middle layer even segment can be cached) I suspecting the 1. scenario can cause the problem at application player site by make the video stream video and audio unsync or stream not smooth compared with scenario 2. Can somebody help for giving me the suggestion please. Thank you

I use encrypted contents in my app . Before playing I request for decryption key which helps in playing content online . I want to play content offline too . So I download the content. But how can I store decryption keys ?

I've been searching all over to find an answer to this question. I know that FairPlay/HLS supports audio Streams since there's obviously audio in video, but I'm wondering if this is practical? Also is there any way to stream FairPlay DRM encrypted content without HLS? or if I use HLS could I create only a single audio bitrate format in order to save on hosting costs? I work on and Audio Book app that requires DRM for some content. Also any links to documentation, videos, tutorials, blog posts... etc on the topic would be awesome too. Very much appreciate anyone who takes the time to answer this. I wish this was more explicitly talked about on the Apple Dev site, but it seems very geared towards video streaming.

When playing an HLS .m3u8 playlist containing fragmented MP4 segments which specify a transformation matrix (defined in the Movie Header Box (mvhd) and Track Header Box (tkhd) atoms in ISO 14496-12), for instance a 90 degree clockwise rotation, the transformation is ignored and the video plays untransformed. Occurs both in Quicktime Player as well as well as Safari when playing the .m3u8 playlist. Concatenating the init.mp4 and .m4s files in the playlist into a file and playing the resulting file does apply the transformation, both in Quicktime Player and Safari. Am I doing something wrong? Are MP4 transformations not supported in HLS only? Rotations and flips seem like a pretty fundamental use case, otherwise video needs to be transcoded.

I've built a web app that uses WebRTC to allow people to video chat in the browser and not be forced to download an app. However, it would be really helpful if iOS users could stream their video using their native camera app and not just the RTC element in the browser. Is this possible? I've found a way to open the native camera app using this HTML: <input type="file" accept="video/*" capture="environment"> However, this only allows the user to upload their video and not stream it.

I'm getting an issue where my fairplay video playback fails by raising AVPlayerItemFailedToPlayToEndTime with Error Domain=CoreMediaErrorDomain Code=-12927 "(null)" I can't find a single hit on google for this error code. I suspect that it has something to do with some kind of bad content in the FPS license response from the server. I can play unencrypted files OK. Its just the FPS content that fails. But my DRM resource loader delegate "acts" like it takes the license fine. I've played other vendor's FPS content using the same code and it works there. All I need is a hint as to what 12927 means. Is there some way to look this up?

We are working on iOT based app where we connect Wi-Fi with dash camera and access video files from dash cam we are loading video link in vlckit ios sdk its working in India in both Wi-Fi connected to dash cam and mobile data connected its not working in US in Wi-Fi connected to dash cam and mobile data is ON its working in US in Wi-Fi connected to dash cam and mobile data is OFF

AVPlayer started to throw unknow error: The operation couldn’t be completed. (CoreMediaErrorDomain error -16190.) Is there any exhaustive list of CoreMediaErrorDomain's errors?

We tried transcoding a video file to "fMP4+HLS+HEVC" using ffmpeg. The produced video is unable to play on iOS devices. Upon testing on mediastreamvalidator, could see Error injecting segment data while its fetching the media file.

Situation My team is uses AVPlayer to play live audio on iPhones. We would like to better understanding why a user experiences buffering. What we are currently doing: We are currently monitor the following AVPlayer attributes: buffering reason indicated bitrate observed bitrate error log events  What we have noticed: Buffering reason - is always toMinimizeStalls due to the fact that the buffer is empty. Indicated bitrate - reports the BANDWITH from the manifest url as expected. Observed Bitrate - Values reported here can be lower than the indicated bitrate yet still stream without encountering any buffers. I would expect values under indicated bitrate to encounter buffers as described here here on the apple developer website Error Log Events - Occasionally the error log will report an error code and message however around 60% of the time we don’t have any details from here that indicates why the user is experiencing buffering. When we do experience error codes there doesn't appear to be any map showing what the error code means. Questions: Is there a way to get signal strength from an iPhone (weak signal would give us some reasoning for buffering) What is the recommended approach for getting reasons for buffering? (How to distinguish between a server side issue and a client side issue) Are there AVPlayer settings we can manipulate to reduce buffering?

I'm using the AVPlayer to streaming video, same as: let strURL = "https://multiplatform-f.akamaihd.net/i/multi/will/bunny/big_buck_bunny_,640x360_400,640x360_700,640x360_1000,950x540_1500,.f4v.csmil/master.m3u8"             if let url = URL(string: strURL) {                 let asset = AVAsset(url: url)                 let playerItem = AVPlayerItem(asset: asset)                 player = AVPlayer(playerItem: playerItem)                 let layer = AVPlayerLayer(player: player)                 layer.frame = viewPlaying.bounds                 viewPlaying.layer.addSublayer(layer)                 player?.playImmediately(atRate: 4.0)             } The video can't play, it'll play normal with rate &lt;= 2.0 on iOS 15.x. Anybody can give me the advise to fix this issue?

HI, I am trying to use mediastreamsegmenter and tsrecompressor but seems like I am unable to make udp connection.
