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).
var reqUrl = url.parse(req.url, true)
var cameraName = typeof reqUrl.pathname === "string" ? reqUrl.pathname.substring(1) : undefined;
if (cameraName) {
try {
cameraName = decodeURIComponent(cameraName);

How to Kiosk Raspberry Pi
Software for the Project:
Raspbian Wheezy Debian Linux
Win32Disk Imager
The CanaKit comes with a pre-loaded SD card that includes the same version of Debian Wheezy that I used for this project. However, in an effort to get a little more speed out of the system, I used the 95MB/s Sandisk extreme listed above. It seemed to help, but I did not bench mark it beyond observation.
Anyway, lets get down to building a Raspberry Pi Web Kiosk.
Step 0: Get all of the hardware.
Step 1: Get all of the software.
