A Novel Multimedia Player Based on Embedded System

This paper proposed a novel multimedia player based on embedded system. Different from normal player, it decodes the audio-video stream using a multithreaded mechanism based timeline, and does not need the traditional driving library for playing media — FFMPEG. The player decides the IDR frame for every group of audio-video stream at first, then plays stream according to the interactive model of audio and video. It makes the best use of decoding acceleration engine of embedded chip, has higher decoding efficiency, and saves a lot of resource for embedded system.
