Playing Multimedia Files on the Raspberry Pi

This chapter covers how to play multiplexed files on the Raspberry Pi such as MP4 files, which consist of both audio and video streams. OpenMAX does not support demultiplexing such files, so you must use a software demuxer such as FFmpeg or LibAV. The libraries available on the RPi do not support the decoding of encoded audio streams, so you need to use a software decoder. Finally, you need to manage the synchronization of video and audio streams.
