mobile-ffmpeg not streaming on iOS #655

Closed dev-manager-uk closed 3 years ago

dev-manager-uk commented 3 years ago

Description We have built an iOS sample application with mobile-ffmeg: https://github.com/dev-manager-uk/ios-ffmpeg

Expected behavior Play tracks when streaming through mobile-ffmpeg

Current behavior When trying to stream using mobile-ffmpeg we get "Operation Stopped. The server is not correctly configured"

Logs some : Error Domain=AVFoundationErrorDomain Code=-11850 "Operation Stopped" UserInfo={NSLocalizedFailureReason=The server is not correctly configured., NSLocalizedDescription=Operation Stopped, NSUnderlyingError=0x6000032a01e0 {Error Domain=NSOSStatusErrorDomain Code=-12939 "(null)"}}

+"The HTTP server sending the media resource is not configured as expected. This might mean that the server does not support byte range requests."

To Reproduce

Any help greatly appreciated :-)

tanersener commented 3 years ago

Can you please give details about what this application is doing, what are the ffmpeg commands used?

dev-manager-uk commented 3 years ago

Yes, it's trying to stream an audio file from either local path or gDrive, through FFMPEG, to iOS Audio player

dev-manager-uk commented 3 years ago

-i pathToTrack/URL -vn -strict -2 -acodec pcm_u8 -f wav -listen 1 -seekable 1 http://localhost:8090/restream.wav

tanersener commented 3 years ago

Your command sends the stream to a server at port 8090. Is your player listening on that port?

dev-manager-uk commented 3 years ago

It does, here's the log:

The sample app is useful for debugging. All it does is play the track through ffmpeg:

Seems to be related to:


when AVPlayerItem receive a video URL , it do the following task:

Send a bytes request HTTP Request, and range = 0 -1
If the response code is 206 and return 1 bytes data, It do the 3th task, if not, AVErrorServerIncorrectlyConfigured error occurred.
continue send other HTTP Request, to download segment of All duration. and the response of VideoData code must be 206

When I run your sample app I see the same errors.

!Connection to tcp://localhost:8090 failed: Connection refused

!Connection to tcp://localhost:8090 failed: Connection refused

!Connection to tcp://localhost:8090 failed: Connection refused

!Error writing trailer of http://localhost:8090/restream.wav: Broken pipe

They're not hard to understand. These are http errors and tell that no one is listening on port 8090.

Playing a stream and serving a stream are two different things. Yes, it seems like AVPlayer supports playing a stream but does not support serving a stream. I also searched this on google and couldn't find anything about it. Can you show me a link or something that proves AVPlayer supports this?

dev-manager-uk commented 3 years ago

Useful that you were able to reproduce!

We're using AVUrlAsset

Here's the code we're using to call the URL:


    func logCallback( executionId: Int,  level: Int32, _ message: String!) {
        print("!" + message)
        if message.range(of: "Input #0") != nil {
            let url = URL(string: FFMPEG_RESTREAM_ADDRESS)!
            asset = AVURLAsset(url: url)

            // Create a new AVPlayerItem with the asset and an
            playerItem = AVPlayerItem(asset: asset)

            // Register as an observer of the player item's status property
            playerItem.addObserver(self,
                                   forKeyPath: #keyPath(AVPlayerItem.status),
                                   options: [.old, .new],
                                   context: &playerItemContext)

            // Associate the player item with the player
            player = AVPlayer(playerItem: playerItem)
        }

It seems to be related to this StackOverflow post

when AVPlayerItem receive a video URL , it do the following task:

    Send a bytes request HTTP Request, and range = 0 -1
    If the response code is 206 and return 1 bytes data, It do the 3th task, if not, AVErrorServerIncorrectlyConfigured error occurred.
    continue send other HTTP Request, to download segment of All duration. and the response of VideoData code must be 206

In my situation , when send range[0-1] HTTP request, the server side give me a 200 OK response, So error occurred.

FFMPEG gives a 200 response, but AVPlayer requires a 206 response

We've now replicated using FFMPEG in terminal, bypassing ffmpeg-mobile, and get the same result.

So I guess it seems that the AVPlayer range request for = 0 -1 is incompatible with FFMPEG stream which returns 200 instead of 206 which AVPlayer requires?

Which means it's perhaps not an ffmpeg-mobile issue but an ffmpeg issue?

Yeah, it is about ffmpeg but I'm not exactly sure that this is an issue.

FFMPEG gives a 200 response, but AVPlayer requires a 206 response

Which log message shows this?

dev-manager-uk commented 3 years ago

Here's a wireshark log that shows the 200 response for bytes 0-1:

dev-manager-uk commented 3 years ago

Is there any way to force ffmpeg to respond with a 206 here?

tanersener commented 3 years ago

Well, it seems like you are using the experimental http server of ffmpeg, which is enabled by -listen 1 option. I think this is why ffmpeg returns 200.

Unfortunately, I'm not familiar with this feature of ffmpeg. I don't know how you can change its behaviour. https://ffmpeg.org/ffmpeg-protocols.html#http lists some options you can try. But I don't know if any of them can fix this error. I'll suggest asking this to ffmpeg developers on ffmpeg-user mailing list.

ok, I'll do that. Thank you for your help!

Sure thing, all here: https://github.com/dev-manager-uk/ios-ffmpeg

I'm still trying to solve this one!

Interesting, thank you. How would you then get ffmpeg to stream through this swift server?
