MediaInfo (GUI or Cmd) is an user interface and a proof of concept for MediaInfo library (Lib or Dll). MediaInfo can be used in your own program without any difficulties, with a static or dynamic library interface. An object containing information about a media file. MediaInfo objects can be created by directly calling code from libmediainfo (in this case, the library must be present on the system): pymediainfo.MediaInfo.parse('/path/to/file.mp4') Alternatively, objects may be created from MediaInfo’s. MediaINFO Digital Library is currently serving clients with varied needs and organizational profiles such as National Libraries, University Libraries, Specialized Libraries, Publishers, Archives. Here's how I get the media info via code (Python). Save this to a file with a py extension (e.g. then run it with the name of a video file as a parameter. Import os import re import subprocess def execCmd(cmd='): return subprocess.checkoutput(cmd, shell=True).decode.splitlines class MediaInfo(object): ' Runs MediaInfo.exe and arranges the output in a more code-friendly way.

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.[4] 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.[5] In 2012 MediaInfo 0.7.57 was also distributed in the PortableApps format.[6]

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.

  • Video: codec, aspect ratio, framerate, bitrate
  • Audio: codec, sample rate, channels, language, bitrate
  • Text: subtitle language
  • Chapters: numbers of chapters, list of chapters[7]

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.
