What is FLV – Flash Video Format

Flash Video is a container file format used to deliver video over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. There are two different video file formats known as Flash Video: FLV and F4V. The audio and video data within FLV files are encoded in the same manner as they are within SWF files. The F4V file format is based on the ISO base media file format and is starting with Flash Player 9 update 3. Both formats are supported in Adobe Flash Player and currently developed by Adobe Systems. FLV was originally developed by Macromedia.

Flash Video FLV files usually contain material encoded with codecs following the Sorenson Spark or VP6 video compression formats. The most recent public releases of Flash Player (collaboration between Adobe Systems and MainConcept) also support H.264 video and HE-AAC audio. All of these compression formats are currently restricted by patents.

Commonly, Flash Video FLV files contain video bit streams which are a proprietary variant of the H.263 video standard. 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. (Flash Player 10 released in 2008 also supports the open source Speex codec. FLV files also support uncompressed audio or ADPCM format audio. Recent versions of Flash Player 9 support AAC (HE-AAC/AAC SBR, AAC Main Profile, and AAC-LC).
