Implicit chapters
=================
mpv will add one chapter per segment entry to the virtual timeline.
By default, the chapter's titles will match the entries' filenames.
You can override set the ``title`` option to override the chapter title for
that segment.
Example::
# mpv EDL v0
cap.ts,5,240
OP.mkv,0,90,title=Show Opening
The virtual timeline will have two chapters, one called "cap.ts" from 0-240s
and a second one called "Show Opening" from 240-330s.
