Abstract
The techniques disclosed herein enable a guest operating system (OS) to access and use a color space conversion component on a host OS. The guest OS provides, via an application programming interface, a request for the host OS to generate media data in a color space format that is used by the guest OS. To generate the media data, the host OS uses a color space conversion component on the host OS, which is more performant than a corresponding color space conversion component on the guest OS because the color space conversion component on the host OS has access to hardware-accelerated functionality. Accordingly, the color space conversion component on the host OS converts media data into the color space format that is used by the guest OS, and stores the media data in memory that is accessible to the guest OS.
