It is very advisable to switch on this option if the system GPU video-hardware and device drivers supports XVideo and more modern rendering systems such as Open GL and VDPAU are unavailable – the speedup is very noticeable even on a fast CPU.

The VIDIO provides an affordable and effective platform on which to develop new 4K and Video over IP products.

That requires a considerable amount of processing power, which could slow down or degrade the video stream; video controllers are specifically designed for this kind of computation, so can do it much more cheaply.

Similarly, the X video extension can have the video controller perform color space conversions, and change the contrast, brightness, and hue of a displayed video stream.

Other compositing window managers such as Compiz also use compositing.

However, on a system with limited Open GL acceleration function, specifically the lack of an Open GL Framebuffer Object or pbuffer, the use of an Open GL environment like Xgl makes xv hardware accelerations impossible.
