Sketch: Record calls and send to graph

[tomastiminskas]

Not sure if we have something implemented to record and send calls to graph, but I was doing some research about how to record calls in Live Kit server.

We need to start recording calls and notify call participants when record starts and ends.

Some LiveKit documentation about recording:
https://github.com/livekit/livekit-recorder?tab=readme-ov-file
https://github.com/livekit/egress

Also when recording starts or ends we should notify room participants this way:

room.sendData({
    kind: 'RELIABLE', // or 'LOSSY' for less critical messages
    message: JSON.stringify({
        type: 'recording_status',
        status: 'started'
    }),
});

Then the apps will implement a listener and show a message or something notifying the participants

I'm not sure about how and who will start the recording or if it will be automatic. As we don't have a room admin I don't think someone could start it, so maybe it should be automatic?

Check client SDKs and implement button to start recording and send to S3

Recording endpoint is pointing to https://chat.sphinx.chat so the entire endpoint call would be to:

https://chat.sphinx.chat/api/record/start?roomName=v5ye-asdf&now=2025-01-16T19:37:38.229Z

We should change the logic where it's handled and include a notification to all participants in the call using the way it's described in the ticket or any other way described in Live Kit documentation.

room.sendData({
    kind: 'RELIABLE', // or 'LOSSY' for less critical messages
    message: JSON.stringify({
        type: 'recording_status',
        status: 'started'
    }),
});

In addition it would be great to include recording state (true/false) in Room metaData. The metaData is received when joining a room and it would be helpful since if someone joins a room after it started being recorded he won't get the notification about recording started, so it should get that information on Room metaData
