Script for transcoding, segmenting and preparing a video file for HLS playback. Used as a demo at 360iDev Denver 2013. Depends on HandBrakeCLI (from http://handbrake.fr/downloads2.php) and Apple's HLS tools (from https://developer.apple.com/streaming/)

This is awesome - thanks for getting back to my tweet. I used something similar to play dvds on an ipad and appletv - but it was a very hacked together VLC script and I didn't even know Handbrake had any command line scripts. I'll have to dig deeper.
