Demo details

This demo shows how you can record a WebRTC session, and replay it later. You can choose to either record a new session (e.g., a videomessage) or watch any of the recordings that may be available (including those you made yourself).

This application makes use of the integrated recording feature in Janus, specifically the individual recording of audio and video streams in .mjr format: these individual recordings are then used for a live broadcasting of the dumped RTP packets through a sendonly WebRTC PeerConnection when you choose to replay them. To post-process these recordings in a more usable format (e.g., .webm for video or .opus for audio) you can make use of the janus-pp-rec tool that is available as part of the Janus code.

Note well:

Please notice that, due to how the original demo page in the repo was conceived to work, this demo will create permanent recordings, which means that a message that you record will be available to other people visiting this demo page. In case you record something by mistake and would like it to be removed, please use the contact form on our website.
