recording all streams in a multiparty call

[utkarshmaximess]

Presently your demo only provide for recording one stream(audio+video). But i want to record audio of all parties participating in the conversation.

@utkarshmaximess , so you have streams (audio and video) and you want to record audio tracks from each of callers?

You need to create a MediaStream and attach audio tracks.

var streamForRecord = new MediaStream();

stream.getAudioTracks.forEach(function(track) {
streamForRecord.addTrack(track);
});

var rec1 = new qbMediaRecorder(streamForRecord);

Something like this.

Multiple audio tracks added with addTrack (like suggested by dimaspirit) are not supported in webm. Only first added audio track is effectively recorded. I just wanted to record 1 callee video but audio tracks for both 1 caller and 1 callee. Any solution for this?

You somehow need to convert all audio tracks into one before recording. check out web audio api, https://developer.mozilla.org/en-US/docs/Web/API/ChannelMergerNode
