Godot Native Camera Plugin

A Godot plugin that provides a unified camera capture interface for Android and iOS using native platform APIs. It enables real‑time camera frame streaming directly into Godot with configurable resolution, rotation, frame skipping, and optional grayscale output.

Key Features:

• Unified GDScript API for Android and iOS
• Enumerate available cameras and their supported output sizes
• Start and stop native camera frame streaming
• Receive raw frame buffers or ready‑to‑use Image objects
• Configurable resolution, rotation, frame skipping, and grayscale capture
• Designed for real‑time use cases (CV, AR preprocessing, custom rendering)

Installation

Before installing this plugin, make sure to uninstall any previous versions of the same plugin.

If installing both Android and iOS versions of the plugin in the same project, ensure that both versions use the same addon interface version.

There are two ways to install the NativeCamera plugin into your project:

• Through the Godot Editor AssetLib
• Manually by downloading archives from GitHub

Installing via AssetLib

Steps:

• Search for NativeCamera in the Godot Editor AssetLib

• Click Download

• In the installation dialog:

  • Keep Change Install Folder set to your project root
  • Keep Ignore asset root checked
  • Click Install

• Enable the plugin from Project → Project Settings → Plugins

Installing both Android and iOS versions

When installing both platforms via AssetLib, Godot may warn that some files conflict and will not be installed. This is expected and safe to ignore, as both platforms share the same addon interface code.

Installing manually

Steps:

• Download the release archive from GitHub
• Unzip the archive
• Copy the contents into your Godot project root
• Enable the plugin via Project → Project Settings → Plugins

Usage

Add a NativeCamera node to your main scene or register it as an autoload (singleton).

Typical workflow:

1. Query available cameras using get_cameras()
2. Choose a camera and desired output size
3. Create a FeedRequest to configure the stream
4. Start the camera feed
5. Receive frames via signals

Example

@onready var camera := $NativeCamera

func _ready():
	camera.permission_result.connect(_on_permission_result)
	camera.frame_available.connect(_on_frame_available)
	camera.request_permission()

func _on_permission_result(granted: bool) -> void:
	if not granted:
		push_error("Camera permission denied")
		return

	var cameras := camera.get_cameras()
	if cameras.is_empty():
		return

	var cam: CameraInfo = cameras[0]
	var request := FeedRequest.new()
		.set_camera_id(cam.get_camera_id())
		.set_width(1280)
		.set_height(720)
		.set_rotation(90)
		.set_grayscale(false)

	camera.start_feed(request)

func _on_frame_available(frame: FrameInfo) -> void:
	var img := frame.get_image()
	# Use the image or raw buffer here

---

Signals

Register listeners on the NativeCamera node:

• permission_result(granted: bool)

  • Emitted after a camera permission request completes

• frame_available(frame: FrameInfo)

  • Emitted when a new camera frame is available

---

Methods

• request_permission()

  • Requests camera permission from the OS

• get_cameras() -> Array[CameraInfo]

  • Returns a list of available cameras

• start(request: FeedRequest)

  • Starts the camera feed with the given configuration

• stop()

  • Stops the active camera feed

---

Classes

CameraInfo

Encapsulates camera metadata provided by the mobile OS.

Properties / Methods:

• get_camera_id() -> String
• is_front_facing() -> bool
• get_output_sizes() -> Array[FrameSize]

---

FeedRequest

Defines configuration parameters for starting a camera feed.

Configurable options:

• Camera ID
• Output width and height
• Frames to skip (performance tuning)
• Rotation (degrees)
• Grayscale capture

Supports fluent chaining via setter methods.

---

FrameInfo

Represents a single captured frame.

Accessors:

• get_buffer() -> PackedByteArray
• get_width() -> int
• get_height() -> int
• get_rotation() -> int
• is_grayscale() -> bool
• get_image() -> Image

---

FrameSize

Represents a supported camera output resolution.

Accessors:

• get_width() -> int
• get_height() -> int
• get_raw_data() -> Dictionary

---

Platform-Specific Notes

Android

• Ensure Android export templates are installed
• Enable Gradle build in export settings
• Camera permission is required at runtime

Troubleshooting:

• Logs (Linux/macOS): adb logcat | grep godot
• Logs (Windows): adb.exe logcat | select-string "godot"

Helpful resources:

• Godot Android export documentation
• Android Studio & ADB documentation

iOS

• Follow Godot’s iOS export instructions
• Camera permission must be declared in the generated Xcode project
• Use Xcode console logs for debugging
