Node.JS function to remux mp4/h.264 video from an IP camera to a HTML5 video tag using FFMPEG
// Live video stream management for HTML5 video. Uses FFMPEG to connect to H.264 camera stream,
// Camera stream is remuxed to a MP4 stream for HTML5 video compatibility and segments are recorded for later playback
var liveStream = function (req, resp) { // handle each client request by instantiating a new FFMPEG instance
// For live streaming, create a fragmented MP4 file with empty moov (no seeking possible).
