HandBrake is a free and open-source digital video transcoding program for Windows, Mac and Linux platforms, originally developed for BeOS by Eric Petit from France in 2003, then ported to other systems, making it a cross-platform solution for video conversion. It is designed to help users convert video files into various formats.

All relevant information of a audio/video file is stored in the file's header area, including duration, codec id, aspect, frame rate, bit rate, sample rate, channels, bit depth, language, etc. MediaInfo can obtain and utilize these info from the header of a media file with ease, which is very helpful for media software developers. If you just want to know the codec info of some movie or music file that could not be recognized or played correctly, you can use MediaInfo to check its technical & tag data.
