I'm having trouble getting an agent implementation...

I'm having trouble getting an agent implementation that just transcribes all participants in a room. right now, my code only runs for the first participant that joins, and the agent leaves when that user leaves. how can I make it transcribe any participant that joins? feels like im missing a configuration step

I generate a JWT when a user joins the room:

Copy code

def livekit_token(video_grant: nil, sip_grant: nil)
    token = LiveKit::AccessToken.new(api_key: Rails.application.credentials.livekit.api_key!, api_secret: Rails.application.credentials.livekit.api_secret!)

    token.identity = self.hashid
    token.name = self.full_name

    token.video_grant = video_grant if video_grant.present?
    token.sip_grant = sip_grant if sip_grant.present?
    token.room_config = {
      agents: [
        {
          agentName: "stenographer",
          metadata: { participant_identity: self.hashid }.to_json
        }
      ]
    }

    token.to_jwt
  end

that seems to only work for the first participant to join the room though.

Copy code

Have you seen https://github.com/livekit/agents/blob/main/examples/other/transcription/multi-user-transcriber.py ?

I had, I originally was doing an approach like this but it seemed like it wasn't exiting properly. I ended up getting it working with one-agent-per-participant, I missed I had to set the JT_PARTICIPANT flag
