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 MPEG-4 Part 14 is standardized as part of the MPEG-4 format in ISO/IEC 14496-14:2003. It is recognized as a container format for audio and video streams and references several filename extensions of which .mp4 is one. The MPEG-4 Part 14 is in many ways identical to Apple's QuickTime format which formed the basis of MPEG-4. However, there are slight differences in compatibility with other previously standardized MPEG features and the added support for IOD or initial object descriptors which describe elementary data streams and set profile information of the resources needed for content playback.
