When I call

await self.room.local_participant.publish_track(self._video_track)

which participant it actually refers to? Agent or user participant?

Thanks for reaching out, Jan. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

how to refer to agent participant to publish the track?

Hey there! To grab the agent participant in a LiveKit room, here are some easy ways depending on the SDK or framework you're using: • Swift SDK: Just use the

agentParticipant

property on the

Room

object to get the agent participant directly. • JavaScript/TypeScript: You can filter the

remoteParticipants

collection to find the one with

kind === 'AGENT'

, and make sure it’s not an avatar worker by checking that the

lk.publish_on_behalf

attribute isn’t there. • React: The

useVoiceAssistant

hook is your friend here—it gives you the agent participant along with its state and tracks. If you want me to dive deeper or share some examples for a specific SDK, just give me a shout!

I am talking about the python solution

I don't have the answer you're looking for. You could also try asking your question: • in one of the other Slack channels or • to https://deepwiki.com/livekit/livekit_composite which is trained on all LiveKit source code If you find the answer, please post it here to help others!
