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.
MediaInfo is a free, open-source, and cross-platform media file information analysis, detection and display tool (written in C++) from France. It can quickly detect the detailed codec and content information of video/audio files. And, it can be easily integrated into any program using a supplied MediaInfo.dll file. As a matter of fact, MediaInfo has been used in many programs such as XMedia Recode, MediaCoder, eMule, and K-Lite Codec Pack. In addition, MediaInfo has included all the functions of current several popular codec viewers. For example: supports for new media formats, provides relevant web links for codecs and playback software, and so on, from soup to nuts.
For common users, when you couldn’t tell what the specific codec or tag info of your movie or music file is, that’s when MediaInfo comes in. For multimedia application developers, MediaInfo is the perfect way for you to get and call technical and tag data from media files.
