FLV

Flash Video is a container file format used to deliver digital video content 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 developed by Adobe Systems.

3GP

The 3GP file format stores video streams as MPEG-4 Part 2, H.263, or MPEG-4 Part 10, and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1.3GPP allowed use of AMR and H.263 codecs in the ISO base media file format, because 3GPP specified the usage of the Sample Entry and template fields in the ISO base media file format as well as defining new boxes to which codecs refer. These extensions were registered by the registration authority for code-points in ISO base media file format.
