CameraFeed

Inherits: RefCounted < Object

A camera feed gives you access to a single physical camera attached to your device.

Description

A camera feed gives you access to a single physical camera attached to your device. When enabled, Redot will start capturing frames from the camera which can then be used. See also CameraServer.

Note: Many cameras will return YCbCr images which are split into two textures and need to be combined in a shader. Redot does this automatically for you if you set the environment to show the camera image in the background.

Signals

format_changed() 🔗

Emitted when the format has changed.

frame_changed() 🔗

Emitted when a new frame is available.

Enumerations

enum FeedDataType: 🔗

FeedDataType FEED_NOIMAGE = 0

No image set for the feed.

FeedDataType FEED_RGB = 1

Feed supplies RGB images.

FeedDataType FEED_YCBCR = 2

Feed supplies YCbCr images that need to be converted to RGB.

FeedDataType FEED_YCBCR_SEP = 3

Feed supplies separate Y and CbCr images that need to be combined and converted to RGB.

enum FeedPosition: 🔗

FeedPosition FEED_UNSPECIFIED = 0

Unspecified position.

FeedPosition FEED_FRONT = 1

Camera is mounted at the front of the device.

FeedPosition FEED_BACK = 2

Camera is mounted at the back of the device.

Property Descriptions

bool feed_is_active = false 🔗

  • void set_active(value: bool)

  • bool is_active()

If true, the feed is active.

Transform2D feed_transform = Transform2D(1, 0, 0, -1, 0, 1) 🔗

The transform applied to the camera's image.

Array formats = [] 🔗

Formats supported by the feed. Each entry is a Dictionary describing format parameters.

Method Descriptions

FeedDataType get_datatype() const 🔗

Returns feed image data type.

int get_id() const 🔗

Returns the unique ID for this feed.

String get_name() const 🔗

Returns the camera's name.

FeedPosition get_position() const 🔗

Returns the position of camera on the device.

bool set_format(index: int, parameters: Dictionary) 🔗

Sets the feed format parameters for the given index in the formats array. Returns true on success. By default YUYV encoded stream is transformed to FEED_RGB. YUYV encoded stream output format can be changed with parameters.output value:

separate will result in FEED_YCBCR_SEP

grayscale will result in desaturated FEED_RGB

copy will result in FEED_YCBCR

void set_name(name: String) 🔗

Sets the camera's name.

void set_position(position: FeedPosition) 🔗

Sets the position of this camera.

void set_rgb_image(rgb_image: Image) 🔗

Sets RGB image for this feed.

void set_ycbcr_image(ycbcr_image: Image) 🔗

Sets YCbCr image for this feed.
