I didn't know how to make an extension to VLC but thx to you I did what I wanted to do.
I'll buy you some cookies in RL if we ever meet.
Your scirpt was lacking one function and it was total playlist duration.
I was pissed since the devs don't care about such function as seen here: viewtopic.php?f=7&t=96760
so I made it and integrated with your script.
I'm going to release my changes under WTFPL since you didn't specify a license for your code.
Teh code
Code: Select all
-- time.lua -- VLC extension --
--[[
INSTALLATION:
Put the file in the VLC subdir /lua/extensions, by default:
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
* Windows (current user): %APPDATA%\VLC\lua\extensions\
* Linux (all users): /usr/share/vlc/lua/extensions/
* Linux (current user): ~/.local/share/vlc/lua/extensions/
* Mac OS X (all users): /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
(create directories if they don't exist)
Restart the VLC.
Then you simply use the extension by going to the "View" menu and selecting it.

The code for playlist duration is [PLD]
Use it how ever you wish.
