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 (container) file and supply them to their respective audio, video, or subtitles decoders.
Notable file splitters
Microsoft AVI splitter - Part of Microsoft Windows.
Haali Media Splitter - demultiplexes MP4 (MPEG-4), M2TS (MPEG transport stream) and MKV (Matroska) files.
FLV Splitter - demultiplexes Flash video files.
Gabest splitter (part of Media Player Classic) - demultiplexes e.g. 3GP, MP4
LAV Splitter - part of the LAV Filters project (open source DirectShow media splitter and decoders).
libavformat (part of the FFmpeg project) - demultiplexes many formats e.g. 3GP, ASF, AVI, FLV, SWF, M2TS, MKV, MOV, MP4, MPG, NSV, NUT, Ogg, RM, AIFF, AU, WAV, etc.
e.g. used in MPlayer and GOM Player
libvlc (part of VideoLAN project and VLC Media Player) - demultiplexes many formats e.g. MPEG transport stream, MPEG program stream, MP4, MOV, 3GP, Ogg, OGM, ASF, WMV, WMA, MKV, FLV, etc.
Nero Splitter
Ogg DirectShow Filters - demultiplexes Ogg container
tsMuxeR, using the Demux output option
MP4Box, command line MP4 multiplexer/demultiplexer with GUIs like My MP4Box
Playback issues
Playback difficulties (such as no playback, no audio, or no video) may result from several or legacy file splitters for a particular file format being installed on an operating system. This causes decoder-to-file-splitter mismatch resulting in playback failure on media players.
