Step-2: run OBS Studio
Step-3: go to file-setting-output-streaming-video bitrate (reduce the video bit rate from 1000 to 333kbps if required, this will reduce network load from mbps to kbps for each user)
Step-4: go to file-setting-streaming-service select custom
In server input /”rtmp://nginx server ip:1935/live/” e.g. rtmp://172.0.0.1:1935/live
In stream key /”any key alpha or numeric/” e.g. 1234
Ok to save setting

Step-2: run vlc player
Step-3: go to tool Preferences-input/codecs-show setting all-input/codec-network caching increase from 1000 to 10000 or 15000 (this will increase the screaming delay but will not disconnect in case of network loss) ok to save setting
Step:4: go to media open network stream and enter rtmp://nginx server ip:1935/live/key e.g. rtmp://172.0.0.1:1935/live/1234
