Providing host media processing functionality to a guest operating system

A system comprising:

• a processing system;
• and
• computer-readable storage media storing a host operating system that, when executed by the processing system, performs operations comprising:
• receiving, from a guest operating system, a request to receive first media data in a first color space format;
• receiving second media data in a second color space format that is native to a sensor of an image capture device;
• converting the second media data in the second color space format into third media data in a third color space format that is used by the host operating system;
• generating the first media data in the first color space format by performing a color space conversion operation on the third media data in the third color space format using a color space conversion component on the host operating system;
• and
• storing the first media data in the first color space format in memory that is shared between the guest operating system and the host operating system.

A method implemented by a guest operating system on a computing device, the method comprising:

• sending, to a host operating system, a request for a color space conversion component on the host operating system to convert first media data in a first color space format into second media data in a second color space format that is used by the guest operating system;
• allocating, in association with the request, memory for the second media data in the second color space format, wherein the memory is shared between the guest operating system and the host operating system;
• sending, to the host operating system, a reference to the memory;
• and
• retrieving the second media data in the second color space format from the memory.
