I have to create an app to live stream and save live stream video.

An app ( which is simple version of cam app as Botslab/Mi home/ ... ) just lives every time, saves video (maybe every 20 mins) to memory stick and watches saved videos on App

I plan to use react-native-webrtc for the project.

But when I read docs, it has a problem: mediaDevices.getDisplayMedia() can help to record video but my skill is not good enough so I can't find a way to use it in React Native.

I have seen https://stackoverflow.com/a/59082227/14745811 but it can't stream HD or fullHD quality

So does anyone have any suggestions?

Of course, a free option because I use my company server.
