FFmpeg Module Introduction

FFmpeg is an open-source computer program that can be used to record, convert digital audio, video, and turn it into a stream. It includes a leading audio/video coding library Libavcodec and more.
Libavformat: For the generation and resolution of a variety of audio and video packaging formats, including the acquisition of information required to decode the decoding context structure and read audio and video frames and other functions, audio and Video format Resolution Protocol, for the LIBAVCODEC analysis stream to provide a separate audio or video stream source.
Libavcodec: For various types of sound/image codec, the library is the core of audio and video codec, to achieve the most visible in the market the function of the decoder, Libavcodec library by other major decoder ffdshow,mplayer such as the inclusion or application.

Libswresample: Original audio format transcoding
Libpostproc: (A simple algorithm for synchronization and time calculation) is used for post-processing, and the postprocessing of audio and video applications, like the de-block effect.
FFmpeg: This project provides a tool that can be used for format conversion, decoding or TV card instant encoding, etc.;
Ffsever: An HTTP multimedia instant broadcast streaming server;
