For ordinary video sites , Concurrency quantity is a very valuable data , In part of the time , The number of concurrencies may be small , But it can also soar in a short period of time and there is no upper limit , At this point, the system needs to have good expansion ability and load balancing ability . So how to distribute for streaming media server RTSP Flow concurrent stress testing to understand the ability of the system ？ I'd like to share with you our testing process .

By using multiple channels RTSP The client pulls the stream , Can achieve concurrent stress testing . about RTSP Client selection , You can choose open source OpenRTSP The client performs pull flow test .

Pull from local server rtsp flow openRTSP -b 1024000 rtsp://127.0.0.1:554/live

Using concurrent pull streaming , You can do this by using scripts , Call it many times , Such as 100 The script is as follows :
