Dacast has a customized OBS Studio platform. In case you are not familiar, OBS Studio is  the most popular free, open-source live streaming software

We have created this custom OBS Studio platform with the goal of simplifying the steps to stream live video when using Dacast.

Dacast’s version of OBS Studio is available at all plan levels. You can download it for free within the encoder set up tab of your Dacast account.

Please note that Dacast OBS Studio does not support multi-bitrate streaming (same as the original version of OBS Studio) but will soon.

What is an Encoder

Encoding is a process used to convert the RAW video files captured by a camera into digital files suitable for live streaming over the internet.

OBS Studio is an example of a software encoder that is used for live streaming. This means that the encoder feeds digital video files to the streaming platform in real time.

Required Encoder Settings

The following settings are required for live streaming with Dacast, regardless of your selected resolution and bitrate:

VIDEO CODEC H.264 (x264 may work)
FRAME RATE 25 or 30
KEYFRAME INTERVAL 2 secs (or 2x frame rate)
SCANNING Progressive
ENCODING BITRATE Constant (CBR)
AUDIO CODEC AAC
AUDIO BITRATE 128 kbps
AUDIO CHANNELS 2 (Stereo)
AUDIO SAMPLE RATE 48 kHz (48,000 Hz)

Versions of Dacast OBS Studio Available

We offer two different versions of Dacast OBS Studio available for download on our Live Encoder Configuration help page

They are also available for download in your account. Go to your Live Channel, click the “Encoder Setup” button, then click the link indicated by the red arrow below:

Dacast OBS Studio - Encoder Setup

1. Legacy Version of Dacast OBS Studio (RTMP Ingest Only)

The Legacy Version has been online for multiple years, and it supports RTMP stream ingest like most of the encoders.

This version of OBS Studio supports Windows 7, 8, and 8.1, and it is available for free download in your Dacast account.

2. Dacast OBS Studio (RTMP Ingest and HLS Ingest for Low Latency Streaming)

The current version of Dacast OBS Studio supports both RTMP stream ingest and HLS stream ingest for low latency streaming options. This capability makes the new Dacast version of OBS Studio the only free direct HLS encoder available on the market.

Additionally, this version offers more reliability for low latency streaming and is easier to set up with pre-defined encoding profiles.

This version of Dacast OBS Studio and its HLS stream ingest capability are available for all our customers.

The current version of Dacast OBS Studio is available for free download in your Dacast account.

Requirements

To download the current version of Dacast OBS Studio, please make sure you have one of the following:

  • Windows 10 (64-bit) with at least 8 GB RAM
  • Mac 10.13 running an i5 or better CPU with least 5 GB of space left on the hard drive of your device

How to Live Stream with the Current Dacast Version of OBS Studio (RTMP Ingest)

This tutorial will show you how to live stream video using the latest beta version of Dacast OBS Studio and our RTMP stream ingest.

If you are using the original version of OBS Studio (not the Dacast customized one), follow this link for a more accurate tutorial.

1. Download the Software

As we mentioned above, navigate to your “Encoder Setup” page in Dacast to download the software.

You may see a warning sign telling you the source of the program couldn’t be verified. Just click “More Info” then “Run Anyway.”

2. Open Dacast OBS Studio

Open the software as prompted:

3. Add your Video Source

Add your video source by clicking on the “+” button in the “Sources” widget:

OBS Studio with DaCast

You can add as many video sources as you want, reorder them and play them by using the eye icon. This allows you to show multiple sources during your stream or even alternate video sources.

4. Open the Settings

OBS studio settings -settings

5. Setup Your Live Stream

OBS Studio with DaCast

On the left side menu, please select “STREAM.”

In “Stream Type,” you should select “Custom Streaming Server” from the drop-down menu. 

For the “URL” field, copy and paste the Stream URL from your Dacast account. Do the same for the Stream Key. 

You can find your Stream URL and your Stream Key by clicking the pencil icon on the far right of the live channel you will be streaming to and then clicking the “Encoder Setup” button to see your encoder sign-in information:

Dacast OBS Studio - Encoder Setup Details

When you click the “Encoder Setup” button, you’ll also find the Login (Username) and Password.  

Click the clipboard icon on the right side to copy and paste into the Username and Password fields in Dacast OBS Studio. Be sure to first check the box for “Use Authentication” in OBS Studio.

6. Start Streaming

By default, you will be using RTMP ingest and the low definition output streaming settings. If you want to run a quick test you can click on “Start Streaming” to see if it works:

OBS studio settings - start streaming

You know that you’re streaming when you see the green square at the bottom of the window and a running counter next to “LIVE” as shown below:

Configure your encoder settings in accordance with the required encoder settings we’ve spelled out earlier in this post.

8. Modify Your Streaming Settings

To modify and choose the output streaming settings of your live stream, go back to your settings. 

On the left side menu, please select “Output.”

Modify the video bitrate according to the stream quality you want to offer your viewer. Common stream qualities include SD and HD (video bitrate range: 800 to 1900):

Resolution and Bitrate Settings

Please select one of the following configurations and ensure your encoder is set up with these exact settings to help prevent streaming issues:

ULD LD SD HD FHD
Name Ultra-Low Definition Low Definition Standard Definition High Definition Full High Definition
Video Bitrate (kbps) 350 350 – 800 800 – 1200 1200 – 1900 1900 – 4500

Modify the audio bitrate to 128.

9. Advanced Settings

If you have the technical knowledge, you can always select the “Advanced” Output Mode to play with more settings but we recommend that you stay in “Simple” output mode.

If you decide to use the “Advanced” Output Mode please make sure to keep the keyframe interval at 2s.

10. Preview Your Live Stream

To check out your live stream, you can use either:

  • Click the “Theme” tab at the top of your live channel that you’re streaming to.

  • Use the “Share Link.” The “Share Link” is a URL that allows you to share your live event on your social media platform. This is also available in the “Sharing” section of your live channel within your Dacast account.
  • View the embedded video player. Use iframe embed code previously embedded on your website:

What Do I Do if I Cannot Get My Stream to Work?

If you are having trouble when you preview your live stream, please follow these steps:

  1. Go to HELP > LOG FILES > SHOW LOG FILES. A file with all your log files will open itself.
  2. Please zip it and send it to support@dacast.com with a note saying that you are using the OBS beta HLS direct ingest software and you cannot get it to work.
  3. Our engineering team will review your logs to see what’s wrong.

Low Latency Streaming with Dacast’s Version of OBS Studio

Please note that if you’re using your own DNS provider via DHCP, you may have a connection issue, preventing you from launching your live stream. 

In that case, we recommend that you update the system to use a public DNS server, such as Google’s DNS 8.8.8.8 and it should solve your problem.

    Hello,

    In standard OBS version we cant find DACAST as service. While using custom option we need to know the server. What is the name of it? We have all settings in our obs and want to use it instead.

    • Etienne Noualhat says:

      Hello Azad.
      All the information you need to use for the custom RTMP options are in the encoder setup of your channel in my.dacast.com
      Tell me if you find everything there.

  2. Franco Diaz says:

    Hello
    I am using OBS 21.2.1 Dacast 5 (exe) version. I have two issues:

    a) After I log out from the OBS App, the OBS icon button doesn’t work if I want lo log in. So I have to download the OBS 21.2.1 App again and again using Windows 10 (64) link, every time I need to get back in. Is there something missing?

    b) In OBS/Dacast I don’t see the “Browser source” in the Sources Menu? Is this because of the OBS 21.2,1 version? Should I be looking at different version to see the browser source link?

    Thanks

    DaCast OBS version does not work with the current OSX Catalina properly. It does not like adding a ‘Video Capture Device’. I am using the blackmagic capture device. The Dacast OBS just freezes and auto closes. No error log or anything, just disappears.
    The regular OBS works, and so does Dacast OBS on an older OSX, but not on this new OSX.

    • Harmonie Duhamel says:

      Hi Corey, I hope you are great. For Dacast OBS on Mac Catalina, here’s how they can get it to work without the freezing and auto-closing:
      > Open terminal and paste the command below and hit enter- OBS should open as normal.
      open /Applications/OBS.app/Contents/MacOS/OBS –args -picture
      > Or the other way is to have them to download the original OBS Studio by going to obsproject.com
      Let me know if you have any other questions, and I would be happy to help.
      Best regards,
