Adding Connections & Live Streaming

This section provides a brief overview of how to get your Encoder Settings into the Larix Broadcaster app from your Vidflex™ platform. 

Read our Live Event Operator article on - Event Day Manager prior to using this section for Larix Broadcaster

Activate Your Stream

If you are more than 30 minutes before a scheduled start of an event, but would like to test your stream, your persistent stream will be in the "Disabled" state. To activate it, click on the "Enable Stream" button, to the right hand side of the stream. Within 1-2 minutes, your stream will be in the "Enabled" state, which will allow you to send your stream from Larix.

Import Larix Encoder Settings

  1. Once logged into your platform, click on the "Encoder Settings" icon next to the persistent stream name

  2. On this pop up, click the "Launch Larix" blue text, which will then open up the application
  3. Once Larix is open you will be prompted to Import settings

  4. Once you click "OK" Larix will confirm that the connection has been imported

  5. When looking at the camera view on the Larix app click the white circle button to start streaming. The white circle turns to red which means the stream is active from Larix, and within 15-30 seconds, your stream will be visible on your preview player

  6. You can now leave your Larix app streaming, and control your events stopping and starting from another device by using the "Go Live" and "End Event" buttons. This is now made even easier with Event Day Manager
