The .flv filename extension and the FLV file format are associated with Adobe System's flash player. It is a container format primarily used for content delivery over the internet and other computer networks. It is an open file format and supports delivery of audio and video streams through players that are compatible with the specification. Flash video, or FLV, has been popularized on the internet by video streaming websites that encode their video in this format. Most web browsers have support for the format through web browser plugins with the exception of Google chrome which has native support for the format.
The 3GP file format and its associated filename extension .3gp is an audio, video, and text container developed by the 3rd generation partnership project. The target market for the 3gp file format is 3G enabled UMTS mobile phones through associated UMTS multimedia services. Though mobile devices operating on high speed networks are the intended hardware associated with playing .3gp files, many PC codec packs exist which grant compatibility for .3gp playback. The format has a basic profile in which files of this format do not reference any external media sources and support for audio, video, and text is limited to a single track.

The FLV format is similar to the SWF file format (also owned by Adobe Systems) in the technique used to encode audio and video streams but differs slightly with multi byte storage in big endian byte order. FLV supports a number of codecs including but not limited to On2 VP6 and Sorensen Spark. FLV files can only have a single and synchronized audio and video stream. The format has a header tag followed by alternating blocks of back pointers and tags.
The 3gp format is standardized in the ETSI technical specification in which support for it is implied in IMS, MMS, PSS, and MBMS carrier services. The format is based upon the ISO/IEC 14496-12-MPEG-4 part 12 standard. As such, video streams in the 3gp format can be encoded in mpeg-4 part 2 or mpeg-4 part 10. Audio streams can be encoded in AMR- narrow band, AMR-wide band, AAC-LC and others.
