Hey Guys, I am looking to add VP9 support to an application and am trying to figure out how to access these APIs on iOS. Is it possible to access the VP9 encoders / decoders without using HLS? Looking for some help on this. Thanks, Norris

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

I have used ffmpeg to transform a video into multiple chunks, the ffmpeg command works fine and I can play the video. I have created an index.m3u8 that contains 4 qualities, each of those qualities contains the chunks of the video, I can play each chunk, but I can't play anything when using the index.m3u8. here is my index #EXTM3U #EXT-X-VERSION:3 #EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1920x1080 http://cdn... #EXT-X-STREAM-INF:BANDWIDTH=2800000,RESOLUTION=1280x720 http://cdn... #EXT-X-STREAM-INF:BANDWIDTH=1400000,RESOLUTION=842x480 http://cdn... #EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360 http://cdn... here is my quality file #EXTM3U #EXT-X-PLAYLIST-TYPE:VOD #EXT-X-TARGETDURATION:8.341667 #EXT-X-VERSION:3 #EXT-X-MEDIA-SEQUENCE:24 #EXTINF:8.341667, http://cdn.... #EXTINF:8.341667, http://cdn.... #EXTINF:8.341667, http://cdn.... #EXTINF:6.873533, http://cdn.... #EXT-X-ENDLIST

Hello, I have an IP Camera that is able to do RTSP streaming. This stream would go to my server, where it will be forwarded in RTSP format to an iPhone device. I would like to know if Apple allows RTSP incoming streaming (both audio and video); are there any specific guidelines for this? NOTE : - i will use Xcode version 14.3.1 swift version 5.8 Thanks,

I am developing an iOS app using SwiftUI, and I want to provide the functionality to download an HLS (HTTP Live Streaming) livestream for offline usage. However, I'm facing difficulties finding specific examples or tutorials on how to achieve this in SwiftUI. Could anyone provide me with some guidance or point me to resources that demonstrate how to download HLS livestreams for offline playback using SwiftUI? I would appreciate any code snippets, libraries, or step-by-step explanations that can help me implement this feature successfully. Thank you in advance for your assistance!

I want to edit the m3u8 manifest file for all the segments of a hd movies that has about 500 ts files. I want to change the url of each one. So far i've had to do it manually and was wondering if there's a software or method to do this very quickly.

Hi, Replay doesn't work on HLS videos (.m3u8) on ios 16 safari when you get to the end of a video. It works on .mp4s, .movs, etc. I have written a github issue on the videojs repo here: https://github.com/videojs/video.js/issues/8345 But i'm starting to think its the new native ios 16 player that is causing issues and not the library itself.

Hello, I am developing a firewall against http attacks at Layer7 layer. And no system (linux/windows/android/bsd/ios version < 16) works flawlessly, except for ios 16 version. İos 16 device screen record (error): veed . io/view/ab86584b-c054-4b70-8c73-6ae9782fabad) Old ios version test (no error): I am using a golang http service in addition to nginx in the opened url. And when I try to access this golang code directly (ios16) I get 503 error from a device. And all this http service does is to set a cookie on the client after getting the useragent and ip information. Code: What new feature in iOS 16 prevents my service from running? and how can i fix this. Note: In iOS 16, the situation is the same in all browsers, not just safari, I tried it on chrome. However, there is no problem when I try it on 15 and lower versions, which is a lower version. Thanks for your help in advance.

I am aware that HLS is required for most video streaming use cases (watching a movie, TV show, or YouTube video). This is a requirement for all apps. However, I am confused as to whether this would also apply to video chat/video conferencing apps. It would be inefficient to upload compressed video using rtmp/rtp, decompress it, and create HLS segments. Low latency requirements only make this worse. So, is it permissible to use other protocols for video conferencing use cases? Thanks

Problem Description This HLS video https://lf3-vod-cdn-tos.douyinstatic.com/obj/vodsass/hls/main.m3u8 starts with noise at 22 seconds play directly on MacOS 12.6.6 Safari，and it also appears on iOS (16.5.1) safari. But there is no noise when playing with MSE on Mac by the third-party open source web playe such as hls.js on Safari. Test tool hls.js test demo: https://hlsjs.video-dev.org/demo/

Hi there, I'm currently making a web application using webRTC. Even though all the SDP info and ICES of caller, callee are well transmitted, the connection was kept failing. The other devices are functioning well. However at just Iphone(13), it's not working. I tried to connect at same network. And it's working. Therefore I think it's a problem about Ice candidates. I read similar post to avoid this issue. And when one of safari's advanced option called WebRTC platform UDP sockets is disabled it's working. Is there a way that I can connect without tuning options of Safari? Thanks. FYI this is one of my Iphone's Ice candidate:842163049 1 udp 1685921535 118.235.10.100 50750 typ srflx raddr 0.0.0.0 rport 50750 generation 0 ufrag 7e7f network-id 3 network-cost 900

Hi, I am using HLS playback for live broadcasting. I am using AVPlayerItem. In live, I found seekableDuration always have some offset from the latest moment compared to the same playback on Chrome or Android. As far as I have digged into, the difference approximately matches the recommendedTimeOffsetFromLive (usually 6~9 seconds on my tests). The problem is, I tried to minimize configuredTimeOffsetFromLive but it does not have any effect. Even if I set it to 1~2 seconds, it is always the same as recommendedTimeOffsetFromLive. I tried to change automaticallyPreservesTimeOffsetFromLive as well, but nothing seems working. How do these properties work and how can I make the time offset minimized?

Hi, I have an HLS content i.e., .m3u8 manifest file but the segments are encoded with **MPEG2Video. ** Is such encoding supported by HLS? Or they only support H.264/AVC or HEVC/H.265? Stream #0:0[0x281]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt470bg, top first), 720x576 [SAR 16:15 DAR 4:3], 3125 kb/s, 25 fps, 25 tbr, 90k tbn Stream #0:1[0x201]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 128 kb/s Thanks.

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

I'm working on live streaming encoder but I cannot start to play live stream correctly if the stream type (#EXT-X-PLAYLIST-TYPE) is EVENT. When I try to play it, the stream starts from the beginning not the current position. When I tested on iPhone 7 (iOS 15.7.8), live streams start correctly but I tested on iPhone 8 Plus (iOS 16.6), live streams start from the beginning. (I tested on other iPhones with iOS 16 or later and the result is the same.) I also tried to add "#EXT-X-START:TIME-OFFSET" tag but it didn't work. Is this behavior a bug or do I have to add some tag to play?

Hello, I'm try to create a working Clear-key HLS stream using Shaka-packager. Shaka packager support only SAMPLE-AES. when implemented, it's looks like the resulting stream is no't playable in Safary browser. This is the example M3U8 file starts: #EXTM3U #EXT-X-VERSION:6 ## Generated with https://github.com/google/shaka-packager version v2.6.1-634af65-release #EXT-X-TARGETDURATION:13 #EXT-X-PLAYLIST-TYPE:VOD #EXT-X-MAP:URI="audio_und_2c_128k_aac_init.mp4" #EXT-X-KEY:METHOD=SAMPLE-AES,URI="https://www.httpstest.com:771/key.key",IV=0x00000000000000000000000000000000,KEYFORMAT="identity" #EXTINF:10.008, audio_und_2c_128k_aac_1.mp4 #EXTINF:10.008, audio_und_2c_128k_aac_2.mp4 #EXTINF:9.985, audio_und_2c_128k_aac_3.mp4 #EXTINF:10.008, audio_und_2c_128k_aac_4.mp4 #EXTINF:10.008, audio_und_2c_128k_aac_5.mp4 #EXTINF:9.985, audio_und_2c_128k_aac_6.mp4 #EXTINF:0.093, audio_und_2c_128k_aac_7.mp4 #EXT-X-ENDLIST I'm looking for: A. a working example of SAMPLE-AES Clear key encrypted HLS (so I will be able to learn from it how it should be defined for IOS) B. help on how to create a clear key working HLS stream for IOS/macOS (Safari)

Hi guys, Setting AVPlayerViewController.transportBarCustomMenuItems is not working on tvOS. I still see 2 icons for Audio and Subtitles. let menuItemAudioAndSubtitles = UIMenu( image: UIImage(systemName: "heart") ) playerViewController.transportBarCustomMenuItems = [menuItemAudioAndSubtitles] WWDC 2021 video is insufficient to make this work. https://developer.apple.com/videos/play/wwdc2021/10191/ The video doesn't say what exactly I need to do. Do I need to disable subtitle options? viewController.allowedSubtitleOptionLanguages = [] This didn't work and I still see the default icon loaded by the player. Do I need to create subclass of AVPlayerViewController? I just want to replace those 2 default icons by 1 icon as a test, but I was unsuccessful after many hours of work. Is it mandatory to define child menu items to the main item? Or do I perhaps need to define UIAction? The documentation and video are insufficient in providing guidance how to do that. I did something like this before, but that was more than 3 years ago and audi and subtitles was showing at the top of the player screen as tabs, if I rememebr correctly. Is transportBarCustomMenuItems perhaps deprecated? Is it possible that when loading AVPlayerItem and it detects audi and subtitles in the stream, it automatically resets AVPlayerViewController menu? How do I suppress this behavior? I'm currently loading AVPlayerViewController into SwiftUI interface. Is that perhaps the problem? Should I write SwiftUI player overlay from scratch? Thanks, Robert

For live content, if the user pauses playback and their current playhead falls out of the valid DVR window, AVPlayer will stop reporting seekableTimeRanges - why does this happen? Is there a workaround? For example: Suppose we were streaming content with a 5 minute DVR window User pauses playback for 6 minutes Their current position is now outside of the valid seekable time range AVPlayer stops reporting seekableTimeRanges all together This is problematic for two reasons: We have observed the AVPlayer generally becomes unresponsive when this happens. i.e. Any seek action will cause the player to freeze up Without knowing the seekable range, we dont know how to return the user to the live edge when they resume playback Seems to be the same issue described in these threads: https://developer.apple.com/forums/thread/45850 https://developer.apple.com/forums/thread/45850
