MediaInfo

MediaInfo is a cross-platform, free and open source program that displays technical information about media files, as well as tag information for many audio and video files. It is used in many programs such as XMedia Recode, MediaCoder, eMule, and K-Lite Codec Pack. It can be easily integrated into any program using a supplied MediaInfo.dll. MediaInfo supports popular video formats (e.g. Matroska, WebM, AVI, WMV, QuickTime, Real, DivX, XviD) as well as lesser known or emerging formats.
