Correct way in new versions of nginx

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}

ffmpeg does not (yet) have the RTMP server functionality. What it does, when it outputs to the rtmp URL is that it outputs the stream, which is an input feed for RTMP servers (like Wowza or similar). Shortly speaking, ffmpeg feeds the real RTMP server with the input which is then being broadcast by that RTMP server.
