Demultiplexer (media file)
A demultiplexer for digital media files, or media demultiplexer, also called a file splitter by laymen or consumer software providers, is software that demultiplexes individual elementary streams of a media file, e.g., audio, video, or subtitles and sends them to their respective decoders for actual decoding. Media demultiplexers are not decoders themselves, but are format container handlers that separate media streams from a file and supply them to their respective audio, video, or subtitles decoders.
