I need to save each participant's audio track to S3. Is there a way to achieve this using start_participant_egress, with an audio_only option?

Yes, you can use the

startParticipantEgress

method to record each participant's audio track individually and save it to S3. According to the LiveKit documentation, you can specify the

audio_only

option when starting a Participant Egress. This allows you to record only the audio tracks of a participant. You will need to provide the participant's identity and configure the output to use S3 for storage. Would you like more details on how to implement this?

@millions-hair-24956 show how to add

audio_only

in egress.startParticipantEgress

It seems likely that you can specify the

audio_only

option when using the

startParticipantEgress

method to ensure only audio tracks are recorded. However, the specific parameter

audio_only

is not explicitly mentioned in the provided data sources for

startParticipantEgress

. Instead, you can configure the egress to focus on audio by setting the appropriate options in the

ParticipantEgressOptions

. Here's a general example of how you might configure the

startParticipantEgress

method:

const egressClient = new EgressClient('https://your-livekit-host', 'api-key', 'api-secret');

const output = {
  filepath: 'path/to/output.mp3',
  s3: {
    accessKey: 'your-access-key',
    secret: 'your-secret',
    region: 'your-region',
    bucket: 'your-bucket',
  },
};

const options = {
  encodingOptions: { audioOnly: true }, // This is a conceptual example
};

egressClient.startParticipantEgress('room-name', 'participant-identity', output, options)
  .then(info => console.log('Egress started:', info.egressId))
  .catch(error => console.error('Failed to start egress:', error));
