## Functions

### cheese_camera_device_new ()

    CheeseCameraDevice *
    cheese_camera_device_new (GstDevice *device,
                              GError **error);

Tries to create a new CheeseCameraDevice with the supplied device. If construction fails, `NULL` is returned, and `error` is set.

#### Parameters

device | The GStreamer the device, as supplied by GstDeviceMonitor |
error | a location to store errors |

#### Returns

a new CheeseCameraDevice, or `NULL`

### cheese_camera_device_get_name ()

    const gchar *
    cheese_camera_device_get_name (CheeseCameraDevice *device);

Get a human-readable name for the device, as reported by udev, which is suitable for display to a user.

#### Parameters

device | a CheeseCameraDevice |

#### Returns

the human-readable name of the video capture device.

### cheese_camera_device_get_best_format ()

    CheeseVideoFormat *
    cheese_camera_device_get_best_format (CheeseCameraDevice *device);

Get the CheeseVideoFormat with the highest resolution with a width greater than 640 pixels and a framerate of greater than 15 FPS for this `device` . If no such format is found, get the highest available resolution instead.

#### Parameters

device | a CheeseCameraDevice |

#### Returns

the highest-resolution supported CheeseVideoFormat.

                                    CheeseVideoFormat *format);

Get the GstCaps for the given `format` on the `device` .

#### Parameters

device | a CheeseCameraDevice |
format | a CheeseVideoFormat |

#### Returns

the GstCaps for the given `format` .

### cheese_camera_device_get_format_list ()

    GList *
    cheese_camera_device_get_format_list (CheeseCameraDevice *device);

Get the sorted list of CheeseVideoFormat that the `device` supports.

#### Parameters

device | a CheeseCameraDevice |

#### Returns

list of CheeseVideoFormat.

### cheese_camera_device_get_src ()

    GstElement *
    cheese_camera_device_get_src (CheeseCameraDevice *device);

Get the source GStreamer element for the `device` .

#### Parameters

device | a CheeseCameraDevice |

#### Returns

the source GStreamer element.
