Code: Select all
-- Playlist total duration
-- Simple extension that shows the current playlist's total duration
-- Lua scripts are tried in alphabetical order in the user's VLC config directory
-- lua/{playlist,meta,intf}/ subdirectory on Windows and Mac OS X or in the user's
-- local share directory (~/.local/share/vlc/lua/... on linux), then in the global
-- VLC lua/{playlist,meta,intf}/ directory.
-- 2021-01-10: extended to show the remaining time of the whole playlist _and_ the whole playlist time:
-- <remaining time in total playlist> / <total playlist time> e.g.:
-- 01:26:22 / 02:58:01
-- ToDo: auto refresh
-- original code from:
