What is FLV?

FLV, which stands for Flash Video (Extenison: .flv or .swf), is a video format developed by Adobe Systems for its Flash Player. It has long been a popular video type used in embedded videos on the internet, including those found on YouTube, Hulu and more. However, as Adobe has announced its official discontinuation of FLV, it is now gradually replaced by HTML5.

  • Windows: Windows Media Player, VLC Media Player, Winamp, MPC-HC, etc.
