FLV Essentials
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.
How to open an FLV file?
In addition to Adobe's official Flash Video Exporter plug-ins like Adobe Animate, you
can now open an FLV through the following ways:
- Windows: Windows Media Player, VLC Media Player, Winamp, MPC-HC, etc.
- Mac: QuickTime Player, VLC Media Player, Winpy Player and more
- Phones and Tablets: PlayerXtreme Media Player and so on.
