Welcome for the dev forum @chloe3!
Here is an example of the Linux SDK, but I don’t think it showcases raw video send capabilities: GitHub - zoom/meetingsdk-linux-raw-recording-sample (courtesy of @chunsiong.zoom)
Another option is Recall.ai. It’s a simple 3rd party API that lets you use meeting bots to send raw audio/video into meeting meetings + capture video/audio without you needing to spend months to build, scale and maintain these bots.
Let me know if you have any questions!
