How Do I Stream using OBS Studio (Windows)?

In this OBS Tutorial for DaCast, we are going to cover how to connect to the DaCast service and get set up for your first live stream.
Open Broadcaster Software is a free to download, open source encoder. 

Anyone is allowed to create their own plugins for OBS so it can be tremendously versatile, and is definitely a powerful video broadcast software and live streamer should have around. However, it does require a familiarity with computer technology to be able to use it effectively.
This is for the Windows version of the Encoder (MacOS version available here

If you are using the DaCast branded version of OBS Studio, follow this link for a more accurate tutorial.

 

Step 1: Create a new Profile

The first thing to do is to create a new profile to which our settings will be saved.

In the Windows Menu bar (top of the screen), go to “Profile” => “New” and set up the desired name. Then click “OK" 

 

Step 2: Add details to Broadcast Setting / Connect to DaCast 

We are now going to link OBS with DaCast and its content delivery network.

In the Menu bar, click “OBS” => “Preferences” and then go to the “Stream” tab. It should looks like this : 

Change the “Stream Type” from “Streaming services” to “Custom Streaming Server”. It will now look like this:

Go to your DaCast Channel and select “Encoder Setup”. Select your Bit-Rate and Resolution, and then select “Other RMTP Encoder”:

Fill in “URL” and “Stream Key” with you DaCast Stream URL and Stream Name, respectively. Then fill in “Username” and “Password” according to the login details of your DaCast account. 

Note: If you are willing to broadcast to a Flash channel, the process would be similar except that Authentication (username and password) won't be necessary. You would simply need to input the Stream URL and the Stream Names and will be ready to start broadcasting. Your "Publish settings" tab in the DaCast BackOffice would look like:

 

Step 3: Start Broadcasting 

You are now all set to broadcast with OBS to Dacast.

You can add multiples sources (camera, audio, display capture, etc.) by clicking the “+” button in the “Source” (bottom of the screen) and remove them by clicking the “-“.

You can also add (“+”) and remove (“-“) “Scenes”. Scenes are presets sources than you can mix together. Later, you can also assign hotkeys to switch between the multiple Scenes you’d have created. To do so, go to the “Hotkeys” tag of OBS’s “Preferences”. 

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

Keyframe interval = 2 or 3 seconds and nothing else , rate control = VBR, profile = baseline.obs_keyframe.png
