EBC Mini Project 03

 Note: In future classes consider breaking this into two projects, one with video and user input and the other audio.

This mini project is a follow up on the audioThru and videoThru labs. At this point you should have both audio and video working in their own threads in one app. This mini project starts there and adds a feature. On user input,
 * 1) have the Video2 display a copy of the current image in Video1.  Video1 is to keep displaying live video.
 * 2) replay the last 5 seconds of audio, while continuing to play the live audio.

You can decide what the user input is. It may be
 * 1) User hits return in the terminal
 * 2) Sensor detects the user
 * 3) etc.

Keep in mind this is on the xM, so the sensors you used before may not work. For example, there is no analog in.

Write a small (less than one page) memo that highlights the features of this mini project and demo it.

Note: If you have issues with Framebuffer 2 (mmap fails), it may not have memory properly allocated. Before running your application, enter this command: echo 4000000 > /sys/class/graphics/fb2/size Courtesy of the BeagleBoard FAQ
