Recording video and stream at the same time

Hello everyone! I have a problem, I need to record and stream at the same time. My NRSK version is experimental 1.9.3. I tried to clone classes, but video doesn’t saving, video has a lot of lags and after video stop, the program has been frozen. Has anyone experienced this? Can you tell me how i can fix this, please?

Hi, do you mean the video is lagged and stopped while using the First Person View function?
