FFmpeg is an open-source multimedia framework that allows users to record, convert, and stream audio and video. It is released under the LGPL or GPL license, making it a versatile tool for developers and end-users alike. FFmpeg provides a complete solution for handling audio and video content, offering powerful encoding, decoding, and streaming capabilities.
At the core of FFmpeg lies libavcodec, a highly advanced library of audio and video codecs. This library was developed with a strong emphasis on portability and quality, with many components written from scratch to ensure optimal performance across different platforms.
