FLV

Flash Video file format

FLV (Flash Video File) is a container file format developed by Adobe Systems for delivering video and audio content over the internet. It is commonly used with Adobe Flash Player, supported by media players like VLC, and can be created or converted using tools like FFmpeg or Adobe Animate. The format uses a lightweight structure with metadata tags, supports streaming via RTMP, and allows for embedding of interactive elements like captions and cue points, making it suitable for web-based video playback.

It is supported by media players like VLC, Windows Media Player, and editing tools such as Audacity and Adobe Audition.
