Possibility to control rotation of Ambisonics by OSC

[bossesand]

As VLC supports 16 channel third order Ambisonics and Sofa files I see a opportunity to create headtracked binaural listening in a simple way.

That is to add the feature to control the listening direction with a simple headtracker that sends osc messages over wifi to the VLC player.

I suggest the OSC quaternions message for used by
https://plugins.iem.at/docs/osc/#scenerotator

Iistening to port 9000 or localy configureablewould be ideal,
My suggestion is to use a osc decoding library from
http://opensoundcontrol.org/cnmat-softw ... -downloads
To simplify the OSC decoding.

This is something that is missing on the "market".
