    In this OBS Tutorial for Dacast, we will discuss how to set up a live stream by connecting the Dacast streaming solution to OBS Studio, a free and open-source live stream encoding software.

    This guide is for the Windows version of the encoder. 

    Video tutorial available here.

    Step 1: Add Details to Broadcast Setting and Connect to Dacast

    Open the settings of OBS Studio:

    OBS studio settings - app settings
    Go to the “Stream” tab. Select “Custom…” from the Service drop-down at the top. You will see two fields: URL and Stream Key. This information is available in your Dacast account.

    Go to your Dacast Live Channel, click the “Encoder Setup” button.

    Copy and paste the Stream URL from your Dacast account in the “Server” field. Copy and paste the Stream Name in the“Stream Key” field. Then, click on the box for “Use Authentication.”

    Fill in “Username” and “Password” using the Login and Password of the live channel. Click the clipboard icon on the right side to copy and paste into the Username and Password fields, respectively, in OBS Studio:

    Step 2: Add Audio and Video Sources 

    At this point, you are prepared to broadcast with OBS to Dacast, but you have the option to add additional sources (camera, audio, display capture, etc.).

    You can do this by clicking the “+” button in the “Source” window at the bottom of the screen and remove them by clicking the “-“:

    You can also add (“+”) and remove (“-“) “Scenes.” Scenes are preset sources that you can mix together. 

    Switch between multiple Scenes you have created by assigning “Hotkeys.” Do this by going to the “Hotkeys” tag of OBS’s “Preferences.”

    Before starting the stream, make sure all the following settings match the below:

    • Keyframe interval = 2 seconds
    • Rate control = CBR
    • Profile = main

    For more settings, please see our Encoder Configuration page.

    Once you are happy with your OBS Studio settings, click “Start Streaming” to begin your broadcast.
