I need help for stream from local file. I read the documentation of the mediasoup client but haven’t found the corresponding api. Is there a way to switch files from mediastream or any way to stream local files? ---

You can use external tool like FFmpeg or GStreamer, create plain transport in mediasoup and stream with plain RTP. Documentation actually mentions this a few times. ---

Then stream from browser using WebRTC. I do not understand what the question is then. Also in this case it has nothing to do with mediasoup specifically. ---

You can use the captureStream API > **[HTMLMediaElement.captureStream()](https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/captureStream)** > > The captureStream() property of the HTMLMediaElement interface returns a MediaStream object which is streaming a real-time capture of the content being rendered in the media element. 1. upload video file to the HTML page 2. attach the video file to a video element src 3. use captureStream to create MediaStream 4. create a producer using the above mediastream tracks ---

I added mediastreamtrack to a mediastream and add it to srcObject of other audio tag. And this audio tag has played the added track. It’s may be a bug off mediasoup?? ---

How can be adding a second `MediaStreamTrack` to a `MediaStream` and just get audio of that track be a bug in mediasoup? Please, let’s not just assume that “everything is a bug in mediasoup”. You are using a `MediaStream` and a `MediaStreamTrack`objects. Those are not “mediasoup API” but browser API. BTW that’s the behaviour of a `MediaStream` when you add more than one audio `MediaStreamTrack`. ---

Can you help me by creating a captureStream () + mediasoup example? I try it but not work. In spite of your solution is basically. ---

I’ll do it when I have free time, but I can’t give any estimations as to when it’ll be done. If you can’t wait you will have to do it yourself. ---
