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.

Providing host media processing functionality to a guest operating system

The techniques disclosed herein enable a guest operating system (OS) to access and use a media processing component configured on a host OS. The guest OS provides, via an API, a request to create an instance of the media processing component (e.g., a codec, an encryption/decryption component, a DRM component). In association with the request, the guest OS allocates space in memory for media data that is to be processed by the instance of the media processing component configured on the host OS. The guest OS stores the input media data in the allocated memory and provides, via the API, reference(s) to locations of the allocated memory. The reference(s) to the locations of the allocated memory enable the host OS to retrieve the input media data and process the input media data using the instance of the media processing component configured on the host OS.
