HLS stream not found

[iamareebjamal]

Describe the bug HLS stream does not start playing because the server throws 404 Not Found for it

To Reproduce Steps to reproduce the behavior:

1. Go to LiveApp
2. Click on 'Create new stream'
3. Start publishing to the stream using RTMP
4. See Broadcasting status as Broadcasting 1.05x
5. Click on play button or use the embed code
6. Observe it says Stream will start playing automatically when it is live
7. It never starts playing. After debugging, the stream GET requests for all resource options of stream fail with 404 Not Found - m3u8, mp4, adaptive_m3u8

Type Status Report

Message /WebRTCApp/streams/248475541525053093655513.m3u8

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Expected behavior The stream should start playing and server should not throw 404

Additional context

Not sure if it'll help but here are the logs. They clearly mention receiving the stream for the stream ID:

Hello, We need more information to identify and reproduce the problem. I have followed exact same steps that you described and published an RMTP stream using OBS and the HLS stream played successfully in the browser. Which software did you use to publish the stream with RMTP? It can be also related to type or encodecing of the stream which you published. Did you publish directly a video file using ffmpeg or created stream from your camera or screen share using OBS, Wirecast etc?

Best Regards, Can

[iamareebjamal]

I used OBS and tested using a media file and I have been using similar steps in a commercial product (mux.com, dacast.com) and it works fine for both. I tried doing it various times. Let me clarify that I was connecting through 1935 for RTMP and 5080 for HLS, I think that's as expected. Tell me if you need more info

[canat]

Can you follow exactly the same steps in the following guide? https://github.com/ant-media/Ant-Media-Server/wiki/Open-Broadcaster-Software-Publishing and write me the result. For RMTP you dont have to to give a port. The URL for publishing will be like this: rtmp://your_server_domain_name/LiveApp To play m3u8 for my stream, I use following Link http://192.168.1.23:5080/LiveApp/streams/857190862347253083045206.m3u8 And if the problem persists, can you send me the link to the media file you are using for testing?

[iamareebjamal]

For RMTP you dont have to to give a port

For "RTMP", I am confused as to how you don't have to give it a port but I did retry and it seems it defaults to port 1935 so giving it a port if it is already 1935 is a no-op. However, it still didn't work. I doubt that the media file is the problem because it's the API which sends 404 but I'll provide it anyway

https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_1mb.mp4

[canat]

Yeah the file is fine. It can play the file for me. I use following link to publish rtmp://192.168.1.23/LiveApp from OBS where 192.168.1.23 is ip address of my Ant Media Server Please double check that you are using always using consistently LiveApp but not WebRTCApp in the URLs

[iamareebjamal]

Yes, confirmed it. I'm using LiveApp and the dashboard is also showing me that it is being broadcasted, so it is definitely receiving the steam

[canat]

What happens when you press the Play Stream button in the following screen? Can you send me a screenshot after waiting a little bit? To be safe can you start the server again using admistrator role. Maybe it cannot write m3u8 realted files to the disk because it does not have necessary permissions.

[canat]

I checked your logs again, following log suggests that the problem can be related to Play URL. 2020-03-23 22:45:17,197 [http-nio2-0.0.0.0-5080-exec-5] WARN io.antmedia.rest.RestServiceBase - endpoint does not exist in this app. I don't get this warning. Please try everything from start with a different simple stream id and double check the URLs.

Best, Can

[iamareebjamal]

It is installed as a service using the installation script provided in the wiki, so it is running as sudo

This is the screenshot.

RestServiceBase - endpoint does not exist in this app. I don't get this warning.

Yes, that's why I wrote in the issue that it is throwing 404 not found.

start with a different simple stream id

Stream ID is autogenerated, right?

and double check the URLs.

I am copying everything from the dashboard, and it is showing broadcasting, OBS is showing LIVE, so how can the URLs be wrong. I am also clicking on the play button in the dashboard itself, so I don't know how can its URL be wrong. I mean both the stream ID and playback URL have the same identifier.

I can give you access to the dashboard. Can you tell me your email?

And for the exact same stream ID /LiveApp/streams/405962443156146838883691.m3u8, it is throwing 404

[canat]

No, stream id is not auto generated. You can choose any arbitrary string as stream id and you dont need to create it in the beginning from the management console. It will accept it automatically.

[canat]

My email address is can@antmedia.io. Yeah access to the dashboard would be nice to solve identify the problem.

[iamareebjamal]

I'm not sure if we are talking about the same thing. I only see the option of Stream Name when creating a new Live Stream and the Stream ID is autogenerated, which is seen even here - https://github.com/ant-media/Ant-Media-Server/wiki/Open-Broadcaster-Software-Publishing#3-configure-obs

Stream Key == Stream ID

Anyway, I have sent you the email with dashboard and credentials

[canat]

You dont need to create a new stream in the dashboard. You can just choose arbitrary stream id in OBS and start streaming. Ant Media Server will automatically create a stream for this id and you will see it on the dashboard. Ok, I received the email, I will check.

[canat]

Hi,

As I written per email, I can play your video file that I published to your server with OBS inside your dashboard and in my browser with HLS player extension. I also used the stream id which you used to publish your stream and it did also play successfully. I could not find any problems in your server installation. I stopped publishing to your server now.

Please follow the Wiki Guide I sent you before step by step, also tune for low latency, change bitrate etc. The URL, I used to play my stream from your server, I also sent you per email.

Best, Can

[iamareebjamal]

Hi, some hit and trial and I got it working. Really thankful for your support. However, I think I got a bug due to which all this happened. Instead of closing this, I'll update the issue so that you can look at it. Give me a few minutes to verify it thoroughly

[chandrikadevis]

Hi @iamareebjamal , I have the same issue. kindly update how did you fix this issue

[unbranched]

@canat Same problem here, only difference is that my stream is rtsp and needs auth.

[mekya]

@unbranched @chandrikadevis

could you please let us know some reproduce scenario? It's likely there is a problem in the pipeline or configuration.
