Hello, sorry to bother you but I do not understand... How do you initialize the variable $name ?

Hello, sorry to bother you but I do not understand... How do you initialize the variable $name ?

$name stands for the name of stream that you'll be publishing at rtmp://localhost/src/ (eg using ffmpeg: 'ffmpeg -i abc.mp4 -c:v copy -an -f flv rtmp://localhost/src/video1' when streamed $name will be 'video1')

And 'src' is the name of application defined under rtmp block. (full path for rtmp stream ---> 'rtmp://server_ip:port/$app_name/$stream_name')
