search for video segments from other files, and will also ignore any
chapter order specified for the main file.
``--ordered-chapters-files=<playlist-file>``
Loads the given file as playlist, and tries to use the files contained in
it as reference files when opening a Matroska file that uses ordered
chapters. This overrides the normal mechanism for loading referenced
files by scanning the same directory the main file is located in.
Useful for loading ordered chapter files that are not located on the local
filesystem, or if the referenced files are in different directories.
Note: a playlist can be as simple as a text file containing filenames
separated by newlines.
``--osc``, ``--no-osc``
Whether to load the on-screen-controller (default: yes).
