The Adobe Flash Player browser plugin is most commonly called a flash player. It allows a browser to auto-detect and play back FLV files on a website through a direct URL link. Besides the Adobe plugin, there are other lesser known server-side flash players. A website visitor still needs to have the Adobe Flash plugin installed to utilize these players.
