I wonder if self hosted Nginx streaming server which uses nginx-rtmp-module found here has any support for any kind of authentication (for example only those who had a specific stream key would be able to stream to server). My search was pointless since I could n't find any where to state something about it. If it does not support, Is there any other way to go around it, for example put the streaming server behind a Nginx proxy and do the job there? I am completely naive to these topics, help me out please.
