MediaInfo

MediaInfo is a free, cross-platform 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. In 2012 MediaInfo 0.7.57 was also distributed in the PortableApps format.

MediaInfo provides a command-line interface for displaying the provided information on all supported platforms. Additionally, a GUI for viewing the information on Microsoft Windows and macOS is provided.

Technical information
MediaInfo reveals information such as:


 * General: Title, author, director, album, track number, date, duration
 * Video: codec, aspect ratio, framerate, bitrate
 * Audio: codec, sample rate, channels, language, bitrate
 * Text: subtitle language
 * Chapters: numbers of chapters, list of chapters

MediaInfo 0.7.51 and newer retrieve codec information optionally from tags or by computation. Thus in the case of misleading tags erroneous codec information may be presented.
