Install FFmpeg on a Linux Box

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.

Serial control of Arduino. After kick-off message is sent from OF and a response is received from Arduino, OF continually updates Arduino with 3 bytes of data via a call and response driven by Arduino.
int bytesReceived[3]; //incoming bytes
void setup() {
pinMode(13, OUTPUT); //LED on 13
pinMode(12, OUTPUT); //LED on 12
Serial.begin(9600);
}
void loop()
