FFMPEG

FFmpeg is a set of free and open-source libraries that allow you to record, convert and stream digital audio and video in various formats. It includes libavcodec, a library for encoding and decoding audio and video, and libavformat, a library for multiplexing and demultiplexing into a media container. The name comes from the name of the MPEG Expert Group and FF, meaning Fast Forward.
