Requires https://github.com/dailymotion/hls.js/
There's a Flask route to serve static JS content from a subdirectory assumed to be named 'dist' containing either hls.js or hls.min.js, but any method of serving static content would work fine.
Set the hostname variable in stream.py to the appropriate value
Note: this is basically the python part of https://github.com/Nesseref/nginx-rtmp-auth plus a bit more Flask to template pages and load the JavaScript HLS player with the correct media location.
