In general, video encoding and decoding on the OMAP5910 consist of three phases. The first phase is video pre-processing where the data captured needs to be converted to the encoder input format, second phase is doing the actual video encoding and decoding, and third stage is video post-processing where the decoded data is converted to the LCD input format. This document demonstrates the video enc
