Here we are focusing to change the cookie at every 120 seconds while playing , in apple avplayer we can't modify cookie after initialisation due to that we followed the approach to using " Resource loader delegate " to pass cookie as a header value .
What I notice is that the playlist file (.m3u8) gets downloaded correctly. Then video file (.m4a) some chunks also gets downloaded. I know that the .ts file is downloaded because I can see the GET request completing on the web server with status 200. I also set a breakpoint at the following line:
loadingRequest.dataRequest?.respond(with: data)
immediately got error from avplayer status as
"The operation could not be completed. An unknown error occurred (-12881) From core media"
Need confirmation on why I am unable to load HLS using resource loader.
is it possible to update cookie value while paying continuously on avplayer.

Example project
I'm developing an iOS radio app that plays various HLS streams. The challenge is that some stations broadcast HLS streams containing both audio and video (example: https://svs.itworkscdn.net/smcwatarlive/smcwatar/chunks.m3u8), but I want to:
Extract and play only the audio track
Support AirPlay for audio-only streaming
Minimize data usage by not downloading video content
Technical Details:
iOS 17+
Swift 5.9
Using AVFoundation for playback
Current implementation uses AVPlayer with AVPlayerItem
Current Code Structure:
class StreamPlayer: ObservableObject {
@Published var isPlaying = false
private var player: AVPlayer?
private var playerItem: AVPlayerItem?
func playStream(url: URL) {
let asset = AVURLAsset(url: url)
playerItem = AVPlayerItem(asset: asset)
player = AVPlayer(playerItem: playerItem)
player?.play()
}
Stream Analysis:
When analyzing the video stream using FFmpeg:
CopyInput #0, hls, from 'https://svs.itworkscdn.net/smcwatarlive/smcwatar/chunks.m3u8':
Stream #0:0: Video: h264, yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps
Stream #0:1: Audio: aac, 44100 Hz, stereo, fltp
Attempted Solutions:
Using MobileFFmpeg:
let command = [
"-i", streamUrl,
"-vn",
"-acodec", "aac",
"-ac", "2",
"-ar", "44100",
"-b:a", "128k",
"-f", "mpegts",
"udp://127.0.0.1:12345"
].joined(separator: " ")
ffmpegProcess = MobileFFmpeg.execute(command)
Issue: While FFmpeg successfully extracts audio, playback through AVPlayer doesn't work reliably.
Tried using HLS output:
let command = [
"-i", streamUrl,
"-vn",
"-acodec", "aac",
"-ac", "2",
"-ar", "44100",
"-b:a", "128k",
"-f", "hls",
"-hls_time", "2",
"-hls_list_size", "3",
outputUrl.path
]
Issue: Creates temporary files but faces synchronization issues with live streams.
Requirements:
Real-time audio extraction from HLS stream
Maintain live streaming capabilities
Full AirPlay support
Minimal data usage (avoid downloading video content)
Handle network interruptions gracefully
Questions:
What's the most efficient way to extract only audio from an HLS stream in real-time?
Is there a way to tell AVPlayer to ignore video tracks completely?
Are there better alternatives to FFmpeg for this specific use case?
What's the recommended approach for handling AirPlay with modified streams?
Any guidance or alternative approaches would be greatly appreciated. Thank you!
I'm developing a tutorial style tvOS app with multiple videos. The examples I've seen so far deal with only one video.
Defining the player and source(url) before body view
let avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../video.mp4")!))
and then in the body view the video is displayed
VideoPlayer(player: avPlayer)
This allows options such as stop/start etc.
When I try something similar with a video title passed into this view I can't define the player with this title variable.
var vTitle: String
var avPlayer = AVPlayer(url: URL(string: "https://domain.com/.../.../" + vTitle + ".mp4"")!))
var body: some View {
I het an error that vTitle can't be used in the url above the body view.
Any thoughts or suggestions? Thanks
Hello,
I'm writing a program to create CMAF compliant HLS files, with encryption.
I have a copy of ISO_IEC_23001-7_2023 to attempt to follow the spec.
I am following the 1:9 pattern encryption using CBCS, so for every 16 bytes of encrypted NAL unit data (of type 1 and 5), there's 144 bytes of clear data.
When testing my output in Safari with 'identity' keys Quickly Diagnosing Content Key and IV Issues, Safari will request the identity key from my test server and first few bytes of the CMAF renditions, but will not play and console gives away no clues to the error.
I am setting the subsample bytesofclear/protected data in the senc boxes. What I'm not sure of, is whether HLS/Safari/iOS acknowledges the senc/saiz/saio boxes of the MP4. There are other third party packagers Bento4, who suggest that they do not:
those clients ignore the explicit encryption
layout metadata found in saio/saiz boxes, and instead rely purely on the
video slice header size to determine the portions of the sample that is
encrypted
So now I'm fairly sure I need to decipher the video slice header size, and apply the protected blocks from that point on.
My question is, is that all there is to it? And is there a better way to debug my output? mediastreamvalidator will only work against unencrypted variants (which I'm outputting okay).
Thanks in advance!
I try to validate low latency HLS fragmented MP4 setup with meadistreamvalidator. I get following error:
Error: Invalid URL

What does that error mean?

Hi, I'm trying to decode a HLS livestream with VideoToolbox. The CMSampleBuffer is successfully created (OSStatus == noErr). When I enqueue the CMSampleBuffer to a AVSampleBufferDisplayLayer the view isn't displaying anything and the status of the AVSampleBufferDisplayLayer is 1 (rendering).
When I use a VTDecompressionSession to convert the CMSampleBuffer to a CVPixelBuffer the VTDecompressionOutputCallback returns a -8969 (bad data error).

In an m3u8 manifest, audio EXT-X-MEDIA tags usually contain CHANNELS tag containing the audio channels count like so:
#EXT-X-MEDIA:TYPE=AUDIO,URI="audio_clear_eng_stereo.m3u8",GROUP-ID="default-audio-group",LANGUAGE="en",NAME="stream_5",AUTOSELECT=YES,CHANNELS="2"
Is it possible to get this info from AVPlayer, AVMediaSelectionOption or some related API?
Hi,
I have a IOS app and we are using fairplay DRM to play videos. In IOS app we are allowing offline download of the videos and hence we are getting a persistent fairplay license. In IOS app everything is working fine.
Now we have used the same app and built for MacOS catalyst. In MAC OS catalyst app we are not able to play the video and getting error code -42650
We are able to get the persistent license from server, but when we play the video with the license we are getting the error. Below are the logs:

Hi,
I have a usecase where I'd like to handle and prevent automatic retries whenever certain errors occur during FairPlay content key requests.
Here's the current flow:
FairPlay certificate is requested and obtained from my server
makeStreamingContentKeyRequestData is called on the keyRequest
The license server will return a 403 along with a body response containing a json with the detailed code and message
The error is caught and handled properly by calling AVContentKeyRequest.processContentKeyResponseError
The AVContentKeySession automatically retries up to 8 times by providing a new key request through public func contentKeySession(_ session: AVContentKeySession, didProvide keyRequest: AVContentKeyRequest)
My license server gets hit with 8 requests that will always result in a 403, these retries are useless
My custom error is succesfully caught later down the line through AVPlayerItem.observe(\.status), this is great
Thing is.. I'd like to catch the 403 error and prevent any retry from being made at step 5, ideally through
public func contentKeySession(_ session: AVContentKeySession, contentKeyRequest keyRequest: AVContentKeyRequest, didFailWithError err: Error)
I've looked for quite a while and just can't seem to find any way of achieving this. Is this not supported at all?

Hello,
I used AVPlayer in my project to play network movie.
Most movie could play normally, but I found the sound will disappear sometimes if I play specified 4K video network stream.
The video will continue playing but audio stops after video is played for a while.
If I pause player and then resume, the sound will be back but disappeared again after several seconds
Check AVPlayerItem status:
isPlaybackLikelyToKeepUp` == true
isPlaybackBufferEmpty` = false
player.volume > 0
According the value above, it seems not cause by empty playback buffer or volume issue. I am so confused for this situation.

Does anyone know if AVPlayer has this limitations when playing high-bitrate movie streams, and are there any solutions?
We're integrating a web based group calling application within a native iOS application and finding that every time a CallKit session gets fully established the web based media streams break, rendering as gray with no audio.
Up to iOS 18 we worked around it by not fulfilling the call start action but that's no longer an option as the audio stopped getting automatically redirected to the speakers. We would now need the CXProvider's didActivateAudioSession callback but that would break the video.
The sample project loads up a simple webpage in a WKWebView which contains a video tag streaming the media from the device's camera.
At the same time it sets up a new CallKit session by requesting and fulfilling a CXStartCallAction transaction.
You will notice that the media doesn't render and, if you are to follow the warnings we left, you will find that not fulfilling the CXStartCallAction fixes it.
Unfortunately that's not a workaround we can use as we need the CXProvider delegate to inform us about audio session changes so we can redirect the audio to the speaker (so the proximity sensor doesn't activate and locking the screen doesn't end the call)
Any insights or workarounds would be greatly appreciated.
We are experiencing an issue with our HLS MPEG-TS streams on Apple devices, where the AVPlayer in our iOS app and Safari jumps back to the start when the player automatically changes quality. This occurs despite the stream still indicating that it is live and there is no change in the seekbar. After testing our streams with the Apple HLS Validator, the only problem that occured was an "Measured peak bitrate compared to multivariant playlist declared value exceeds error tolerance"-Error.
On Chrome and on our Android-App this playback bug does not happen. Has someone else experienced similar issues with the AVPlayer?
Hello, we have HLS stream app and we use AVPlayer for HLS stream. We want to implement dynamic resulotion feature as user's selection. For example, if user want to watch only 1080p user has to watch only 1080p but we have tried to implement "preferredMaximumResolution" and "preferredPeakBitRate" parameters and but AVPlayer does not force it which means that setting preferredMaximumResolution= CGSize(width: 1920, height: 1080) player does not only force to play 1080p profile, player drops resulotion to 720p but we do not want 720p stream if user selected 1080p resulotion. Is there any method to force it even if stream stalls? Thank you in advance

Hello,
I submitted a Request for a Deployment Package. However, I have not received any emails yet. Could you please let me know when I can expect a confirmation message?
Thank you.
Case-ID: 9391388
Our application uses timed Metadata as part of a rating control system.
We noticed a problem in production and diagnosis shows that we stop receiving timed Metadata on iOS18 only
Our live streams are primed with metadata at least once per second but we are seeing extended gaps in receiving this content, in excess of 10 minutes.
We have also observed that this happens more as the player climbs the bitrate ladder, and doesn't happen if we cap to a low resolution
i.e. a preferredMaximumResolution of 768x432.
Furthermore, if we throttle network conditions after we stop receiving metadata the we start receiving them again.
Following is a simple example that demonstrates the above behaviour, unfortunately I cannot share the live stream endpoint which is primed with metadata publicly, but can provide privately to Apple to reproduce the problem.
