Plays video back as a series of full-window images
This option decodes incoming video (first video to load), but plays them back as series of full-window images. That is, a single image element, that gets updated 24 times a second, instead of playing the video back within an efficient video element. I have no idea why you might want this option, as it pretty crude up and uses up a lot of CPU, but you can right-click to save a single frame from the video to disk, as a PNG file. This might be useful if you need to take a lot of snap shots of some video and don't want to have to hassle with cropping a window-grab. Quality of the images is pretty high; near lossless.
