Add delayed end to launchVideo

[csdf27]

I have zero javascript knowledge so forgive me if this is a stupid question, but I wanted to introduce a delay to the video stop event to account for the fact that even once VPX has started, nothing appears on screen for a few more seconds, and I want the loading video to continue to be visible for that time. My attempt was to change the myGameStarted function to the following (for a 3 second delay):
function myGameStarted(ev) {
setTimeout(mainWindow.launchOverlay.bg.clear(0xff000000),3000);
}
But this appears to have zero effect. An alternative was just to comment out the gamestarted event hook entirely, which works fine except I think video continues running in the background somewhere which is a bit wasteful. And when you exit the table, the loading video briefly reappears again.

Any suggestions?
