Because the supporting degree for audio/video formats varies from media device to media device, it is not possible for the same video to be played properly on every device. And with the advent of more and more video formats, it's harder to get a piece of hardware that's compatible with all media file types on the market. Even on a computer, it is impossible to install decoders for all media formats. In this case, multimedia format conversion tools come in handy.

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.
