The M4V makes use of both the H.264 and MPEG-4 video codecs. It is similar to the MP4 file format and its structure is based on the QuickTime media file format. M4V files use M4V extension similar to how extensions are used in MP4 file formats. The audio encoding in M4V is also the same as MP4 files and features lossless encoding, scalable lossless coding, MP3, MP2, MP1, CELP, HVXC, TWINVQ, TTSI (Text to Speech Interface) and SAOL (Structured Audio Orchestra Language).
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.
