AVIcodec is a useful tool you can use to extract all the information you need from you video files.

Using AVlodec you can know every detail of the film that you are getting ready to watch. You’ll see how long it lasts, its resolution, the KB per second of its playback, as well as other information. But what is more important, why it really stands out, is because it can identify all of the codecs you’re missing in order to watch your videos.

In addition, if you would like, AVIcodec provides information about all of the codecs you already have installed.

Nevertheless, AVIcodec only notifies you of the ones that you need to install in order to see your videos, but it does not download them automatically, rather it provides the information necessary so that you can go to the site in question and get them directly.
