CodecInstaller

Ever had a movie where you could hear only the sound but there were no video? Or only video and no sound?
That's almost certainly a codec missing! CodecInstaller is here to help you understand which codec you need and to let you install it in minutes.
CodecInstaller is a Windows program that detects the Audio and Video codecs installed on your system, analyzes files to understand which codecs they require and suggests you to install them.

This program can be used to analyze files: it supports avi, mpeg, wmv, wma, ogg, flac, mpc, mp3, mp4, wav, wx and will show technical data such as width/height and ratio, length, video codec, framerate, size, bitrate, total frames, quality factor and metadata such as title, album, year (if available)

CodecInstaller can also be used to distribute video files on a CD, to be sure that who receives the CD will have all the necessary codecs installed: with a single tool he will be able to check if the codecs are already installed and up-to-date.
CodecInstaller contains a MovieLauncher that displays informations about the distributed video file (author, plot, director...) along with a screenshot and a 'Play' button

This program is available in several languages: English, Italian, Russian, Spanish, ...
