Kurento group call example : Can we record each individual user's mediapipeline separately?

In Kurento Group call example is it possible to record each individual user's mediapipeline separately?

Solution

  • Yes, you can record each user's WebRTC media element separately. A couple of suggestions:

    • Make sure you record in WEBM format, so you avoid transcoding
    • Start recording once the media is flowing. You can do this by listening to the MediaStateChanged event, or checking the status of media in the WebRTC element for that participant.
    • Consider recording your files in external storage, such as S3, to prevent running out of space

    You'll have to connect the recorder to the outgoingMedia element, located in the UserSession. You can add the recorder initialisation in the constructor, and the listener for the MediaStatechangedEvent similar to the IceCandidateListener, so you start recording once media starts to flow between the client and the media server.
