I'll give that a try. I suppose you don't want a patch of such a hack?

I have a small wrapper around libVLC which I use in my application. It
raises a callback to the application when the playback state changes.
I have some vaguely defined 'open' state which is supposed to be set
once a file/stream/etc has been opened and is ready to be played.
However since a lot of the initializing happens asynchronously in
separate threads after the input state has been changed to PLAYING_S
it's all a bit hackish.

The specific reason I want to use "audio-es" is that I want to make
decisions based on whether the input has audio and/or video. I'd like
to add goom if there is only audio and no video stream for example.
