Subsonic - can't get it to work

Hello Everyone,
I just installe subsonic from the dashboard.

I can acces the web interface, but i can’t get it to detect any media in the media folder, It says that there is no transcoder so I played a bit with symlinks as many forum suggest to do.

I also changed the user that run the service, so it’s my main dashboard user rnning it now

More than that, the icon in the dashboard is RED.

The log doesn’t show significant informations …

Well …i can’t get it to work … any ideas ?

Thx
