Provides a rudimentary on-screen video display using libsdl.
A framerate of zero means video will be displayed as quickly as possible.
In 1-channel mode, input data is assumed to be grayscale, with each input item mapping to a single pixel.
In 2-channel mode, the first channel is Y for every pixel while the second channel alternates between pixels values for U and V.
In 3-channel mode, input channels are assumed to be matching triples of YUV values, one byte per pixel, per channel.
