MP4 & MOV File Splitter

Splitter (demultiplexer) for MP4 and QuickTime video files.


Demultiplexer (splitter) for the MPEG-4 container. Filter splits MPEG-4 files (.mp4, .mov, .f4v, .3gp, .dv, .dif, etc.) into separate audio, video, close caption, timecode, etc. streams.


  • Support for playback with speed != 1.0, incl. with a negative rate (for video streams without temporal compression).
  • Support for start and stop times from IMediaSeeking::SetPositions().
  • Merging separate audio streams.
  • Extended time code processing.
  • Playing files that have not been fully processed (Movie Fragments handling).
  • Processing separate DV files.
  • Automatic detection of PCM audio type (little or big endian).
  • Lots of fixes for problematic mp4 files.
Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.
