How to live stream video with DaCast new BETA 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 branded one), follow this link for a more accurate tutorial.
1/ Download the software
You may see a warning sign telling you the source of the program couldn’t be verified. No worries, this program is secure. Just click on “more info” and then on “run anyway “.
2/ Open DaCast OBS Studio:
3/ Start by adding your video source. To do so, please click on the + button in the sources widget :
You can add as many video sources as you want, re-order them and play with them using the eye icon if you want to show multiple sources during your stream or even alternate video sources.
4/ Click on Settings :
5.1 On the left side menu, please select STREAM
5.2 In Stream Type, you should see “DaCast streaming as a service” by default; if not, please select it.
5.3 Now let’s get your DaCast OBS encoder key.
For this, you need to login into your DaCast account. Then please go to PREFERENCES > ENCODER KEYS:
Copy the OBS encoder key and paste it in the OBS key encoder field of the OBS Software. Click REFRESH YOUR CHANNELS LIST
Note on your encoder key: if you want to regenerate it to make sure no one else is streaming on your channel, you can do so in your DaCast account and then copy paste the new encoder key.
6/ You should now see your list of live channels when clicking on the drop down menu, if not, click again on “Refresh channels list”.
Select a channel and click OK.
7/ 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.
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”:
8/ To modify the output streaming settings of your live stream, go back in SETTINGS (same as step 3).
9.1 On the left side menu, please select OUTPUT
9.2 Modify the video bitrate according to the stream quality you want to offer your viewer:
For a standard definition, aim for 1000-1200, for HD you will go up to 1900-2000 and for full HD (1080p) you will need to go up to 4500.
Make sure your internet speed connection is double the video bitrate you set up, otherwise you will have buffering issues.
9.3 Modify the audio bitrate
10/ 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 .
11/To check out your live stream, you can use either :
- The “Preview” button available in the publish settings section of your live channel
- The “Share Code” that is an URL allowing you to share your live event on your social media platform. This is also available in the “publish settings” section of your live channel within your DaCast account
- The JS or iframe embed code, previously embedded on your website
What if you cannot get your stream to work?
- Then please go to HELP > LOG FILES > SHOW LOG FILES
- A file with all your log files will open itself
- Please zip it and send it to email@example.com saying that you are using the OBS private beta HLS direct ingest software and you cannot get it to work

Note on the DNS used
If you’re using your own DNS povider via DHCP, you may have a connection issue, preventing you to launch your live stream. In that case, we recommend that you update the system to use a public DNS server, such as google’s DNS 220.127.116.11 and it should solve your problem.
