Hello,

I need a way to provide the ‘proxy\_pass’ argument from external script  
for hls streaming. One way will be to use exec\_pull with rtmp module,  
but this means to convert hls to rtmp, and run ffmpeg - pretty  
cumbersome. If there is a way to do something like \*\* proxy\_pass  
`my_script original_request` \*\* (my\_script is in backticks), it will be  
ideal.

Situation: I need to choose dynamically the server where I pull the hls  
video stream from. Some of the upstream servers (usually 2-4 in total)  
may be down or slow at the moment where the request comes to the local  
nginx, so I need to dynamically choose the ‘preferred’ one. On top, I  
have different login credentials for those, and a limit of logins per  
server.

Almost sure nginx will have some way of doing it - it does anything  
imaginable - and few things beyond.

Any suggestion appreciated,  
Thanks, George.
