It's ok, I don't really need a blocking _load().
Still I have a lot of difficulties to use get_meta()
Which event should I way for so I'm sure the media is loaded/parsed?
What is the algorithm/steps I should use so it works?

The best would be to create a kind of "libvlc_MediaParsingFinished"
and then call libvlc_media_get_meta():

media_load() --> non blocking, launches the media parsing
wait for libvlc_MediaParsingFinished event
call media_get_meta()

And everything (of course) without calling media_player_play()

I still don't understand what you want ;)
Do you want:
1 - libvlc-control.lib, libvlc-control.pdb... (.ie a vlc-sdk.zip for windows)

2 - code that loads libvlc-control.dll/.so at runtime
I can do that, but it depends on C++/Qt, I need to change it to plain C...

Anyway, as I told you, the best is to create a
vlc-sdk-win32-snapshot.zip in complement of vlc-win32-snapshot.zip
every night by configuring buildbot + make package target.
