FFmpeg is an open source computer program that can be used to record, convert digital audio and video, and convert them into streams. It includes the leading audio/video coding library libavcodec. FFmpeg is developed under Linux, but it can be compiled in most operating systems, including Windows. This project was initiated by Fabrice Bellard and is now hosted by Michael Niedermayer. It can easily realize the mutual conversion between various video formats, for example, the video avi recorded can be converted to the flv format used by video websites.
