| 18 | * Contains implementation of a class EmulatedBaseCamera that encapsulates |
| 19 | * functionality common to all emulated camera device versions ("fake", |
| 20 | * "webcam", "video file", "cam2.0" etc.). Instances of this class (for each |
| 21 | * emulated camera) are created during the construction of the |
| 22 | * EmulatedCameraFactory instance. This class serves as an entry point for all |
| 23 | * camera API calls that are common across all versions of the |
| 24 | * camera_device_t/camera_module_t structures. |
