HTTP Live Streaming is a protocol originally developed by Apple and it allows you to stream A/V media over HTTP.
And it has, apparently, pretty widespread support in most of the major web browsers, servers and content delivery networks. So I guess that's how iTunes/VLC/Plex/Kodi/et al. has implemented their streaming? Never heard of it before, but it looks pretty cool.
It looks really easy to implement with the help of FFmpeg:
ffmpeg -i movie.mp4 -c:v libx264 -preset veryfast -hls_time 10 -f hls test.m3u8
This command takes an input file, splits it up into 10 second long segments,
writes them to disk as
.ts files and adds the file names to a
To serve this playlist on a web page, you could add this HTML:
<video src="http://example.com/path/to/playlist.m3u8" height="300" width="400">
Then you just serve all the segments, playlist file and the page itself with a regular web server.
And boom! Live streaming!
