Spanish version available here.

In this tutorial, we will explain step-by-step how to start live streaming on a Dacast live channel using OBS Studio broadcasting software (available for free). Note that this guide is valid for Mac and PC.

Before starting, you will have to download the latest version of OBS Studio; if you don’t have it, you can download it here

Once downloaded, click on the left option as shown below to start live streaming with OBS:

OBS V27 - Dacast live stream

Steps in your Dacast account 

In your Dacast account, go to the Live Streams section. 

From this section, you can stream from an existing live stream, or create a new live stream.

In this example, we will stream on our existing live stream called “OBS V27”. To do so, I’ll click on the live stream title to open the settings.  

Once in the live stream of your choice, click on “Encoder Setup” as shown below:

You should now see this window: 

Encoder Setup Dacast RTMP

In the dropdown menu, select “OBS Open Broadcaster Software” as shown below:

You should now see the following information:

In this window, you will find all the information you will need to enter in OBS. 

Steps in OBS Studio

Now, go to the OBS window that you left open earlier. You should see a similar window: 

OBS App general view

1 – Add stream source(s): 

With OBS Studio open, the first step is to add the stream source to OBS. To do so, click the plus icon (+) under Sources, and choose Video Capture Device as shown below: 

Video capture device OBS27

In our case, we will use our webcam, so we’ll select “Create New” and change the source name to “webcam”, then click OK. The webcam appears on this list, and we click OK to add it:

In the preview window, you can size and position the webcam window. 

Next, we’ll open OBS settings by clicking on the Settings option on the bottom right corner.

If you are streaming to anywhere but China, you have 2 options:

On the left menu, open the Stream settings. In the Service field, select the Dacast option as shown below:

Or on the left menu, open the Stream settings. In the Service field, select the Custom option as shown below:

If you are streaming to China, you can only use custom as a service.


Now, the only thing you need to do is to copy the Encoder Key provided by your Dacast account, in the Encoder Setup window we left open earlier:

And paste it to the Encoder Key field in OBS:

When you’re done, you can click on OK.  

You are now ready to live stream, but before going live, we recommend you to look over at the encoder configuration and settings page here, to ensure the best compatibility with Dacast and OBS Studio.

Once you have been reviewing your encoder configuration, you can click on Start Streaming on the OBS general panel right side. The green light and time counter tell you that everything looks good.

Back to your live stream in your Dacast account, close the Encoder Setup window. 

In the General tab, there are 2 options to preview your live stream, both under the Sharing section: 

  • Share Link: copy and paste it in a new browser tab to see your live stream. You will also share it with your viewers later on.  
  • Preview: a quick way to test your live stream.

You should now see your live stream correctly. You are ready to share it with your viewers via the different Sharing options.  

To go live, make sure the Live Stream Online option is enabled as shown below:

If you enable the Live Stream Online option, don’t forget to click on Save at the bottom of the page.
