@pedro.serras, there are 2 ways to do this:
Method 1
Use the native Zoom APIs to build a meeting bot, which can grab separate video streams per participant: Using the IZoomSDKRenderer* videoHelper to record multiple participants
Method 2
If you don’t want to build and manage meeting bots forever, an alternative is to use the Recall.ai API.
It’s a simple 3rd party API that lets you use meeting bots to get raw audio/video from meetings, with separate streams per participant. With this method, you don’t need to spend months to build, scale and maintain these bots.
Let me know if you have any questions!
