Mousai Player

Mousai Player is an audio and video player for Windows.
It will let you play files with any format, without requiring you to install codecs.

The program interface will show you three separate windows. In the first one, you will be able to choose the files to play. You can pick single files or entire folders. The program will make a playlist with the files you picked, or the playable files in the folders you selected. You can manually delete individual files from the list, or clear it completely.

The second window will show the controls that will affect the file being played (Previous, Start/Pause, Stop, Next) as well as the volume control and information about the file, like its name and duration. You can set the program to repeat a file endlessly, or click on a button to switch to full screen or suppress the video window.

In the video window you will see the video being played, if it is a video, or a bar visualization, if you are playing an audio file. Double clicking on this window you will switch to full screen mode.
