Visualizations for audio only...?

[dbrb2]

Hello,

Using command line VLC options, and pass them in when playiong an audio only filre, I can add an audio visualization. However, if I then use these same parameters to play a file that has both audio and video, then the video and the visualizations both load in seperate windows. I can see why this makes sense in some situations - is there a way, using purely command line parameters, to tell vlc to add a visualization if there is only audio, but to use the video in place of the visualization if a video track exists?

Cheers,

Ben
