I could solve this problem using mp4parser library. Thanks much to author of this library 🙂 Add below dependency in your gradle file: compile ‘com.googlecode.mp4parser:isoparser:1.0.2’ The solution is to stop recorder when user pause and start again on resume as already mentioned in many other answers in stackoverflow.

Is it possible to create a MediaStream containing MediaStreamTrack instances from two different sources/elements? Yes, you can do it using the MediaStream.addTrack() method. But Firefox will only use the initial stream’s tracks into the Recorder until this bug has been fixed. OP already known how to get all of it, but here is a reminder … Read more
