Windows Media Player 12: Video codecs
To properly play video (and even music files), Windows Media Player required an appropriate codec. Codecs are small programs that encode digital signals in a file or data and decode. Only in this way, the player can interpret the streams as a music or film and play correctly. If a codec is missing in the system, the corresponding video file cannot be played. You will receive an error message.

Because Windows Media Player is well equipped with and all major audio and video formats - including 3GP, AAC, AVCHD, MPEG-4, WMV and WMA and AVI, DivX, mov, and XviD files, this error message generally does not appear.
