Abstract
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.
