I'd like to plug and play from a usb stick that is full of mp3s. I thought of 2 ways: configuring system to trigger vlc when mp3 encountered or set up a button in oap to open vlc.... This option would make using vlc a lot easier. For now you have to exit oap to get to rpi and then launch vlc. If I want to create the button, what path to vlc do I use?
