How to Test RTMP Streaming Load testing

I have a task in which we have to test the Mock Interview Video, In it, the Interviewee and Interviewer are connected via Video.

So we have to test if the Video is properly recorded or not. (Video crashed or not ) When the number of users increases the load on a server will also increase, So basically it's a Load Testing,

if yes then I want to know more about them.

If not then is there anything else that you can suggest to me.
