+// Entry point to the Video Capture Service API.
+// The service hosts two VideoCaptureDeviceFactories. The "regular" factory
+// provides access to the capture devices connected to the system. The "fake"
+// factory uses the same interface but provides access to a set of fake devices

Is the "fake" one only used for testing? If yes, I would suggest separating
production interfaces with testing ones.

Ack. The Fake factory is to be shipped as part of production builds.

+// which can be configured through the FakeVideoCaptureDeviceFactoryConfigurator
+// interface.
+interface VideoCaptureService {
+  ConnectToDeviceFactory(VideoCaptureDeviceFactory& request);
+  ConnectToFakeDeviceFactory(VideoCaptureDeviceFactory& request);
+  ConnectToFakeDeviceFactoryConfigurator(
+      FakeVideoCaptureDeviceFactoryConfigurator & request);

nit: no need to have a space before "&"

Done.
