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.
M4V is a file format developed by Apple for the iTunes store's content and is very similar to the MP4 file extension. M4V is supported exclusively by Apple devices. Other video formats like MP4 and MOV can be converted to M4V in order to run on Apple devices. The most common difference between the M4V and MP4 formats is that M4V offers DRM-Copyright Protection which prevents the copyright of media content. To play a DRM-protected M4V file the computer needs authorization by opening the iTunes account used for buying the media file. However, if the files are not protected by DRM, the user can just rename the file extension from M4V to MP4 in order for it to be recognized by non-apple devices.

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 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).
