OK, after doing more research myself I'm pretty sure that nginx can't proxy HLS streams.


It can proxy (pull) RTMP streams, however if I understand it correctly, these streams have to be statically configured in configs (which is not my use case).

I'm building a demonstration streaming system (for educational purposes - teaching system design) and I'm trying to figure out whether Nginx can be used as an HLS reverse proxy in conjunction with Envoy (for sticky load balancing).


I have the backend servers that convert RTMP into HLS. Now in front of that, I want to have an autoscaling pool of reverse proxies that I have load-balance to using Envoy based on the stream (so that the same stream ends on the same process if possible).


What I need from Nginx then is 2 things:

*	Correctly proxy HLS streams.
*	Report overload situations to Envoy, so that envoy can bounce to a different replica if one gets overloaded.

Is this possible? Any links to documentation or examples would be greatly appreciated as well.


Thanks in advance,
