install chromium on raspbian jessie

get these chromium debs (THEY ARE ALSO IN THIS FOLDER):

wget https://dl.dropboxusercontent.com/u/87113035/chromium-browser-l10n_45.0.2454.85-0ubuntu0.15.04.1.1181_all.deb
wget https://dl.dropboxusercontent.com/u/87113035/chromium-browser_45.0.2454.85-0ubuntu0.15.04.1.1181_armhf.deb
wget https://dl.dropboxusercontent.com/u/87113035/chromium-codecs-ffmpeg-extra_45.0.2454.85-0ubuntu0.15.04.1.1181_armhf.deb

adding an init.d script:

look at /etc/init.d/skeleton for the script template
after creating your own, chmod a+x myscript
sudo mv myscript /etc/init.d
update-rc.d myscript.....tba...

OR

...tba...

Install FFmpeg via CLI on Linux box

These steps walk through installing a static binary of any ffmpeg version on to your linux machine. If you want to compile from source, there are several ways to do so. Here's the official guide. Tested and works on an AWS EC2 Ubuntu instance, but should work on any Linux machine.

SSH into your instance and become root

	// No complicated Pixel Library needed.
	// Tested with WS2812B 4 pin versions.
	// Modified by Sam Decrock to resemble NeoPixel API
	// Modified by http://jos.ph to incorporate more of NeoPixel examples
	// 20160510 ... verified works with Arduino 1.6.5 and simblee module
	// >>> using 3.3v > 5v level shifter between pin 6 and NeoPixels
