Mediasoup – WebRTC video conferencing

You can use WebRTC for emitting raw data p2p, not just audio/video streams, right? Or would websockets be preferred if you wanted to, say, broadcast JSON objects to whoever was listening?

Yes, you can use WebRTC DataChannels for sending custom text/binary data on top of a ICE+DTLS connection. BTW mediasoup supports DataChannels.

Any question or comment about mediasoup?

What advantages does sending data over WebRTC have over sending data over websockets?

DataChannels are transmitted over the same UDP/ICE "connection" that is used to transmit audio and video packets. So if you plan to send real-time data (for example: real-time subtitles, metadata related to the current video position, etc) by sending such a data over DataChannel it will reach the remote without delay over the audio/video. If you use WebSocket to transmit the data, there may desynchronization between audio/video and data because they use a different network path.

You said it yourself: it can be done peer 2 peer. A websocket will have a server in between.
