The S16_LE audio format is hard coded in vlc so no problem with it

But looking at the code I found that the audio-method command is broken in vlc-git, if you want to use it you have to omit the "=" character... .

With this bug vlc doesn't even try to load the alsa stuff and that's why you don't have the dbus error.

However after some code modifications I made a little step forward.

With my test version I have no longer the dbus error but still no sound (error in the alsa dsp plugin at the start of transcoding)...

I'll do other tests this weekend.
