In the basic configuration of BigBlueButton, we naturally pay attention to DSGVO compliance and ensure that there is no possibility of BBB recording conferences. But what if you want to record a webinar and make it available to others? Simple. That's what OBS is for.
Open Broadcaster Software
OBS is an open source software for video recording and real-time broadcasting. It is available for Linux, macOS and Windows operating systems.
OBS setup for macOS
Since the software is very powerful and extensive, the configuration can be a bit time-consuming. I myself use macOS and show here my setup, which I could have used well when I created my first screencast via OBS.
What do I need?
- Software OBS for recording image and sound signals.
- iShowU Video Capture as an extension to record audio signals from the computer.
- App audio MIDI setup to manage the audio sources.
How do I configure OBS & Co?
- iShowU Video Capture
- Install the app as described - and that's it.
- Audio MIDI setup
- Search for Audio MIDI Setup in the Spotlight search and select/launch the app.
- Click on the +sign at the bottom left and select Create device with multiple audio outputs.
- In the name of the newly created audio device multi-output device click once and change the name. I have named it OBS Audio Setup.
- Now select Output (integrated) under Main Device at the top.
- Below that, set the sample rate to 44.1 kHz.
- Now select the audio devices output (integrated), iShowU Audio Capture and if necessary Bluetooth headphones, like in my case the AirPods Pro.
- Finished configuring, the app can be closed.
- OBS - Open Broadcaster Software
- Settings: First, go to the settings on the bottom right and click on Audio on the left side. Now deactivate all audio devices and confirm with Okay.
- Scene: Click on the +sign at the bottom left of the scene window, create a new scene and name it.
- Sources: To the right of this, click the +sign in the Sources window and select Window Capture. The actual source is then selected from the drop-down menu at the bottom. All windows that are selectable are displayed there.
- Sources: Click on the +sign again and select Audio Input Recording and assign a name, iPods Pro for me. In the dropdown menu select the headset, for me the iPods Pro and click on Okay.
- Sources: Click the +sign again and select Audio Input Capture and give it a name, System Audio Capture for me. In the dropdown menu select the headset, for me the iShowU Audio Capture and click on Okay.
- The rest of the configuration can be done according to your taste and can be adjusted at any time. For more information, see OBS and the OBS Wiki.
