### How to use Haivision KB encoder with RTMP

> **Getting Started**
>
> If you haven't already, begin by following the [Getting Started](https://docs-preview.optiview.dolby.com/pr-863/millicast/getting-started.md) tutorial to start your first broadcast. You'll need your *RTMP publish path* and *RTMP publish stream name* for the steps described below.

To get started, log into your [OptiView Real-time Streaming Account](https://streaming.dolby.io/signin). Enter your KB web interface, switch views to the Channel Control Center, and create a new channel.

Follow the Create Channel Wizard prompts to create a channel as normal:

1. Enter the desired channel name.
2. Identify your live source for the channel input.
3. Choose RTMP for the channel output and copy the RTMP publish path from the *Publishing* tab of the stream token.
   <br />
   RTMP URL: `rtmp://rtmp-auto.millicast.com:1935/v2/pub`
4. Enter the RTMP publish stream name from your OptiView Real-time Streaming Dashboard.
   <br />
   Stream Name: `myStreamName?token=3bc330607a15a0ecebebd8c9ee2a559fd143c937174bd276e213a96425bb107e`

With the broadcast credentials set up, the stream is ready to go live. To view the stream, navigate back to your newly created token and switch to the *Playback* tab. From the Playback tab, copy the *Hosted Player path* URL and open it in your browser.
