iOS WebRTC: Record remote audio stream

[Jayesh Mardiya]

I am working on an audio streaming application with recording functionality for a receiver. I got stuck at the point where the user wants to record audio stream on the receiver side.

[Pawan Bhardwaj]

You find any solution.?

[Shraddha Susare]

Does anyone got the solution for this?

[Pawan Bhardwaj]

Please check the commit .. it exposes a method in peerconnection to record remote audio and video.

[Shraddha Susare]

Is there any other way for recording only remote audio, like using AVAudioSession or something like that?

Sorry for a stupid question, but probably one easy to answer. How do I get to that commit? Just pulling the latest git? And where is that method? Thanks.

[Pawan Bhardwaj]

I am still exploring something like this

[Pawan Bhardwaj]

yes git has those changes on master branch .

[Sanjay Kumawat]

did anyone found a solution for this?

[Pawan Bhardwaj]

Yes i am able to expose remote audio stream(in android) by making changes in JavaAudioDeviceModule and WebRtcAudioTrack classes and rebuilding it again

Hello,

          Was anyone able to do it successfully in iOS?

I am using the aws kinesis webRTC library in my iOS app. That uses GoogleWebRTC as a pod under the hood. I am able to play the remote audio & video inside the app. I am also able to record the remote video. However, even after weeks of research I am unable to find a right way or hook for getting the Remote Audio Sample Buffers that can be written into a file. My understanding was that there would be some way to get the existing AVCaptureSession or AVCaptureAudioDataOutput of the RTC session, to which I can set a SampleBufferDelegate to. Unfortunately, there is no documentation or link that suggest so or offer a solution. Is this something that cannot be achieved in iOS at all?
Any pointers or snippet from someone who has achieved this successfully would be of great help!.

TIA.

Biju

I can help you record the remote and local audio streams from WebRTC but I need help in recording the remote video

[Biju Chandran]

@sanjay In iOS? Sure I can help with remote video recording. How do we start?

[Sanjay Kumawat]

Please check you mail

[Piotr Sochalewski]

@sanjay could you please share your solution for recording remote audio track?

[yimu wei]

can you rolve it ?

[Tyler Healey]

Good grief.
Was this solution really taken offline?

Could anyone please provide a solution for locally saving a remote video and audio stream as a single video file? This seems like an obvious use case but there is very little help to found for it.
