  • Sharing webcam between guest and host OS
    Patent number: 9389896
    Abstract: A system, method and computer program product for implementing a video camera that is accessible by different Virtual Machine GOSs and the Host system. A standard USB video camera is build into a Host system. A VM running a Guest OS is launched on the Host system. The Guest OS has virtual driver for the Host video camera. The virtual driver is connected to a virtual USB bus, which communicates with a special Host library over a Virtual Machine Monitor (VMM). A special Host side VM application acquires and processes video data from a standard Host system video processing API that communicates directly with a Host-side virtual camera driver. Video frames are provided via the Host-side VM application to the virtual USB bus and to the virtual driver. Host applications or other VMs can acquire video streams from the Host USB camera simultaneously.
