The "slide show" is just a very crude cycling through images, with n seconds
delay before moving on to the next image (n >= 1).
By "playback", we mean playing back the images at a very precise frame rate (24
or 30 fps for 2048 horizontal resolution images), with the usual "movie player"
kind of controls (pause, play, forward, back, etc.). This would probably
require quite a bit of clever work in pre-caching the images as OpenGL textures
in order to achieve frame rate, or possibly having one thread handle the
interface and a second thread reading images ahead of when they are actually
needed. It needs to be a good movie player, although it only needs to play
back a list of individual frames; in contrast to something like VLC, it does
not need to understand movie formats like Quicktime or AVI, nor does it need to
play back sound (for now, anyway).
