M2v

M2V is an MPEG-2 Packetized Elementary Stream. It contains only video related data.

M2V files are normally multiplexed (muxed), which is the process of adding audio data and perhaps other streams such as subtitles, before use. M2Vs are created by demultiplexing an existing MPEG-2, or by converting another video format to MPEG-2.
