What is a Video Player?
A video player is a type of application that can play videos on your computer. It can open files in video formats such as AVI, MP4, MOV, WMV, FLV, WEBM, MKV, among others.
Video players are often called "media players" because they're also capable of playing music or other audio files, such as MP3, WAV, OGG, and FLAC.
