How to Capture High Definition Video Using the Beaglebone Black Under Linux Bryan Blancke 11/7/13 Executive Summary This tutorial details the steps required to set up a Beaglebone Black to capture high definition video and store it to an output directory. In the steps there are explanations of what tools and software is needed to set up the environment for the beaglebone to work with linux in order to capture high definition video content. keywords H2604 Compression Format Ffmpeg Beaglebone Black OpenCV 1 Embedded Linux Video4Linux Introduction The Beaglebone Black is a powerful microcomputer at a very affordable price. The Beaglebone Black is great for image processing applications due to its hardware and software flexibility. The Beaglebone can have a variety of systems installed on it which is part of its great flexibility in applications. With embedded Linux, image processing software such as OpenCV can be used which is an open source software made for computer vision systems. In this tutorial a description of how to use the Beaglebone Black to capture high definition video on embedded linux will be given in step by step detail. This gives one a solid start to building computer vision projects and solutions on a beaglebone microcomputer. Tutorial Before one can begin, the beaglebone needs to be set up with a linux operating system and opencv needs to be installed. Then, a directory must be created to keep the required code files that are used for computer vision capture and image processing. These processes are covered in other tutorials. Code is available online to support such applications in which modifications can be made to suit specific requirements or code can be developed from scratch. Once the necessary architecture is in place the beaglebone is ready for building compu
