CHAPTER 14
Images, Video, and Audio

In this chapter, USB peripherals are attached to the Beagle board so that it can be used for capturing image, video, and audio data using low-level Linux drivers and APIs. It describes Linux applications and tools that can be used to stream captured video and audio data to the internet. Open Source Computer Vision (OpenCV) image processing and computer vision approaches are investigated that enable the Beagle board to draw inferences from the information content of the captured image data. Capture and playback of audio streams are described, along with the use of Bluetooth audio. The chapter also covers some applications of audio on the Beagle board, including streaming audio, internet radio, and text-to-speech.

EQUIPMENT REQUIRED FOR THIS CHAPTER:

  • A Beagle board (preferably one with HDMI and USB)
  • Linux USB webcam (ideally the Logitech HD Pro C920)
  • USB audio and/or Bluetooth adapter
