问题
I need to restream a live stream which is in UDP protocol using nginx RTMP module. So the final stream will be in RTMP protocol. I have tried the command below in the configuration file of nginx(inside the RTMP server)
exec_pull ffmpeg -re -i udp://ipaddress:portnumber -f flv rtmp://localhost/$appname/$streamname;
When I am writing the rtmp stream link in VLC I am not able to get any display. Can anyone help me?
