Setup

HLS streaming from node

Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.

loosely based on https://gist.github.com/bnerd/2011232

// loosely based on https://gist.github.com/bnerd/2011232
// requires node.js >= v0.10.0
// assumes that HLS segmenter filename base is 'out'
// and that the HLS playlist and .ts files are in the current directory

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
