Detect DVD menu from UI
by Jonathan Dieter-2

Rate this Message:
I am attempting to write a simple UI for xine that will primarily be
used to watch DVDs on a home theater system running MythTV. I have a very simple remote control with only eight buttons: up, down, left, right, play, stop, esc and mute. I would like use up, down, left, right and play as select when I'm navigating DVD menus, and then as volume up, volume down, seek -60s, seek +60s, and play/pause when the movie is playing. To accomplish this, I need to be able to detect whether or not we're in a DVD menu. How can I do this using the xine API?

How can I do this using the xine API? UI, so have patched xine's default ui to handle multiple keybindings if one is for a menu. Attached is the patch. The only thing I don't like is that the variable that tells us whether we're on a menu or not is global.
