AVIcodec

When you want to watch the videos you recorded during a trip or listen to the songs you created using only your smartphone, you first need to make sure you have all the appropriate codecs for playing these files.

You can use AVIcodec, a user-friendly application that can analyze a file and display the codecs it requires for smooth playback.

One of the benefits of this application is that it can process an entire folder of files at the same time, so you do not need to spend a lot of time if you want to examine numerous videos and songs.

Once reviewed, each file displays a complete report regarding the audio and video codecs it needs.  

The next step is left to you, the user: you need to follow the links specified for each of the codecs, download and install the corresponding packs, then play the files.

What's more, you can explore all the multimedia codecs and filters installed on your computer, be they audio, video, DirectShow or DirectX. You can also get details regarding its state (enabled or disabled), version, vendor and the full path to its location. Also, you can easily disable a codec or filter if it triggers a conflict with another codec pack you want to install.

One thing needs to be emphasized: considering this project has not been updated in a few years, the codec links it includes might sometimes be invalid or they might lead to discontinued projects. In other words, you might find yourself in the situation of manually searching for an adequate codec pack, according to the information supplied by AVIcodec.
