RTMP streaming is simply sharing content from your computer (entire screen, separate app or window, webcam signal, etc.) to Stage on Hopin with the best video and audio quality possible.
Note: Streaming to the Hopin Stage via RTMP requires a third-party app, e.g. OBS.
Setting up the RTMP stream
- Open the Hopin event Dashboard
- Choose Venue → Stage tab (Stages tab for Multiple Stage setup on the advanced plans)
- Switch to RTMP Stream tab
- Copy Stream Key (unique key generated for every event) and RTMP URL (standard URL used to stream to Hopin, that is across all events)
Now let's open the OBS app.
- Open the Settings menu on the bottom right corner of the app
- Choose Stream tab on the left sidebar
- Set Service option to Custom
- Paste the Server (rtmp://global-live.hopin.to:5222/app) and the Stream Key (generates per event and is unique)
- Click OK for changes to take effect
The Stream will now be directed from OBS to Hopin. We only need to choose the source Input capture: video capture device is your webcam, Window capture is sharing the app window, and Media Source is sharing video or audio from the file on your computer.
- Click on the plus (+) icon under the Sources menu
- Choose Window Capture if you will be screen sharing (Perfect choice to stream your Zoom, Google Meet, or MS Teams call directly to Stage on Hopin)
- Choose the Window you will be sharing from (Zoom app or browser window)
- Finally, with all Settings set, we can click Start Streaming button.
That's it, your stream will be displayed on the Stage at Hopin within 15 seconds.
In case you are new to streaming, here are our recommendations for streaming over OBS to the Stage on Hopin.
Setting up OBS
Tip: The best quality you can get on Stage over RTMP is using the following settings:
Bitrate: 5000 kbps
Keyframe Interval: 2 seconds
- Open the Settings menu
- Switch to Output on the left sidebar, set Output Mode to Advanced and select the Streaming tab on the top of the Settings menu
- Set Bitrate to 5000 Kbps
Note: this is excessive and max bitrate supported. Going with 3500 Kbps will be sufficient for the Full HD 1080p stream. Check other options at our Recommended Encoder Settings guide.
- Make sure the Base and Output Resolution is the same
- Double-check the Aspect Ratio set to 16:9
- Check the Common FPS Values to be 30
Tip: On a low internet bandwidth, you can cheat and stream with 1280x720 (Output Resolution). Most attendees will not be able to tell the difference.
- Open the Advanced tab
- Set the Color Format to NV12, Color Space to 709 and Color Range to Full
Note: In case you are not sure what to do, we recommend having someone from the tech team to be around during your event to help with RTMP settings and configuration.
Smooth transition between Backstage and any content streamed over RTMP
Once you switch from Backstage to RTMP you can simply click Start Streaming and the RTMP stream will override the Backstage cutting off the Backstage stream. That means the only way to have a smooth transition is to:
- Go live on Backstage first
- Start RTMP stream after you are already live on Backstage and wait till the Backstage stream will be cut off by the RTMP stream. The switch happens automatically. No need to reload the page or wait.
In case you started RTMP stream first, the Broadcast button on the Backstage will be grayed out and you would need to:
- Click Stop streaming over RTMP using OBS
- Open the Backstage (it should not display Streaming over RTMP and should have the Broadcast button on the top right corner of the Backstage)
- Click Broadcast and wait ~10 seconds for the Backstage stream to start.
