-// Entry point to the Video Capture Service API.
-// The service hosts three VideoCaptureDeviceFactories. The "regular" factory
-// provides access to the capture devices connected to the system. The "fake"
-// factory provides access to a single fake device that generates test frames.
-// The "mock" factory provides access to a set of mock devices provided by the
-// client, which are useful for verifying that the service implementation
-// operates these devices correctly.
