What is FLV

Flash Video is a container file format used to deliver video over the Internet using Adobe Flash Player (initially produced by Macromedia) versions 6-10. The audio and video data within FLV files are encoded in the same way as they are within SWF files. But SWF is not the only Flash format. FLV files (Flash Video Files) are a binary file format that delivers "bitmapped" video, limited to one video and one audio stream per file, over the Internet to the Macromedia Flash Player version 7. The format has quickly established itself as the format of choice for embedded video on the web. Notable users of the Flash Video format include YouTube, Google Video, Yahoo! Video, metacafe, Reuters.com, and many other news providers.

Commonly, Flash Video FLV files contain video bit streams which are a proprietary variant of the H.263 video standard, under the name of Sorenson Spark (FourCC FLV1). Sorenson Spark is an older codec for FLV files but it is also a widely available and compatible one, because it was the first video codec supported in Flash Player. The Flash Video FLV file format supports two versions of a so called 'screenshare' (Screen video) codec which is an encoding format designed for screencasts. Both these formats are bitmap tile based, can be lossy by reducing color depths and are compressed using zlib. The second version is only playable in Flash Player 8 and newer. Audio in Flash Video files is usually encoded as MP3. However, audio in Flash Video FLV files recorded from the user's microphone use the proprietary Nellymoser Asao Codec.
