FLV (Flash Video) is a digital video file format developed by Adobe Systems for use on the Adobe Flash Player platform. The format is designed to be highly compressed, making it well-suited for online video streaming and distribution.
FLV files use the H.264 or VP6 video codecs and the MP3 or AAC audio codecs to compress video and audio data, respectively. This allows for high-quality video playback with relatively small file sizes, making it a popular choice for online video content, such as YouTube videos and other web-based video players.
In addition to its compression capabilities, FLV also supports a range of video and audio settings, such as frame rate, bit rate, and resolution. This makes it an ideal format for video delivery over networks with varying bandwidth capabilities.
FLV files can be played back on a variety of media players, including Adobe Flash Player, VLC, and QuickTime, and can also be converted to other more widely supported video formats like MP4 or AVI using compatible media conversion software.
Overall, FLV is a widely used video file format that provides efficient and high-quality video playback for online video content.
