Chapter 10
Embedded Graphics and Multimedia Acceleration
In this chapter we will describe frame rendering and layer mixing techniques to provide a simple human–machine interface (HMI) in addition to multimedia rendering on displays. We briefly touch on graphics application programming interfaces (APIs) and their use in composing images for embedded displays.
Given that embedded applications often mix low power requirements and high-quality media, SOC devices often include dedicated hardware acceleration functions to support real-time decoding and encoding of high-definition compressed media streams such as MPEG4. In this chapter we will describe the frameworks and APIs for video capture, encoding, and decoding.
We make no attempt to cover the ...
