So far so good...

Yes I did but I couldn't find a recent vlc build with this sdk folder, I 
use binaries provided by pacman instead.

Following the forum discussion below I couldn't use envars on my windows 
machine for locating VLC plugins:

I've got gem_videoVLC loading only if I start pd like this:

pd/bin/wish86.exe pd/tcl/pd-gui.tcl

and it's enabled when I copy lib/vlc/plugins/ to the parent folder from 
where libvlccore.dll resides, next to Gem in external folder. I also 
have to launch this command line once before starting pd:

lib/vlc/vlc-cache-gen.exe lib/vlc/plugins/

At least this issue could be resolved with deken without the need of 
installing VLC.

there are both x86 and x64 vlc binaries available, but I'm using x64 
binaries since I've almost found out why gem_videoVLC doesn't load
