What is FLV?
FLV, or Flash Video, is a preferred file format that is designed for web playback, offering high rates of compression to deliver video over the Internet using Adobe Flash Player (formerly known as Macromedia Flash Player) version 6, 7, 8, or 9. Yet FLV files cannot be played back directly and they must be embedded in an SWF file. The most common approach is to use an SWF file that functions as a media player with screen and playback controls. Notable users of FLV are YouTube, Google Video, Myspace, Metacafe, Dailymotion, iFilm, Music, eVideoShare, StreetFire, etc.
