videoQ(which folder, clip0, clip1, attributes, progressBar, priority)
From pinHeck Wiki
Works exactly like the normal video command, except it schedules this video to begin playing as soon as the current one ends.
A typical usage might be:
playSFX(0, 'P', '9', 'X' + random(3), 255); //Win dialog!
video('P', '9', 'Z', noExitFlush, 0, 255); //Win video!
numbers(0, numberFlash | 1, 255, 11, modeTotal); //Set graphic #0 to show how many points we got in this mode
videoQ('P', '9', 'V', noEntryFlush | B00000011, 0, 255); //Show mode total along with the graphic of the points.
Your kernel can send this all in one shot, and then the A/V processor will handle the timing from there.
