FFmpeg 2.0 is out!

This post was made with an older stylesheet

FFmpeg is one of those things that you are using everyday without knowing/noticing which is both a success for the project (because it performs well and without problems on what it does) and a bad thing for it (remains in the shadow of the applications with less chances of financial support and contributions).

FFmpeg is used by applications like VLC, MPlayer, xine, HandBrake, Blender, Google Chrome and even YouTube and Facebook! It is literally everywhere assuming the task of supporting a huge list of codecs, formats and protocols in situations of playing, converting, recording and streaming audio and video. It consists of many components with libavcodec being maybe the most popular.
