CameraFrameStreamer Class¶

Description¶

FrameStreamer gets data from CameraDevice and generates frame to feed filters.

If you are looking for a customizable frame feeder to use your own video source, it is not available yet in the latest EasyAR SDK, but will be available as subclass of FrameStreamer in some later releases.

Constructor¶

C: void easyar_CameraFrameStreamer__ctor(easyar_CameraFrameStreamer * * Return)¶

C++11: CameraFrameStreamer()¶

Traditional C++: CameraFrameStreamer()¶

Java: public CameraFrameStreamer()¶

Objective-C: + (easyar_CameraFrameStreamer *) create¶

Swift (since EasyAR SDK 2.1.0): public convenience init()¶

attachCamera¶

Attach CameraDevice to the streamer. Streamer will not start to streaming until a CameraDevice is attached.

Attach null object will detach previous attached CameraDevice from tracker.

C: bool easyar_CameraFrameStreamer_attachCamera(easyar_CameraFrameStreamer * This, easyar_CameraDevice * obj)¶

C++11: bool attachCamera(std::shared_ptr<CameraDevice> obj)¶

Traditional C++: bool attachCamera(CameraDevice * obj)¶

Java: public native boolean attachCamera(CameraDevice obj)¶

Objective-C: - (bool)attachCamera:(easyar_CameraDevice *)obj¶

Swift (since EasyAR SDK 2.1.0): public func attachCamera(_ obj: CameraDevice?) -> Bool¶

peek¶

Peek the latest frame from streamer.

C: void easyar_CameraFrameStreamer_peek(easyar_CameraFrameStreamer * This, easyar_Frame * * Return)¶

C++11: std::shared_ptr<Frame> peek()¶

Traditional C++: void peek(Frame * * Return)¶

Java: public native Frame peek()¶

Objective-C: - (easyar_Frame *)peek¶

Swift (since EasyAR SDK 2.1.0): public override func peek() -> Frame¶

start¶

Start to streaming frames.

C: bool easyar_CameraFrameStreamer_start(easyar_CameraFrameStreamer * This)¶

C++11: bool start()¶

Traditional C++: bool start()¶

Java: public native boolean start()¶

Objective-C: - (bool)start¶

Swift (since EasyAR SDK 2.1.0): public override func start() -> Bool¶

stop¶

Stop streaming.

C: bool easyar_CameraFrameStreamer_stop(easyar_CameraFrameStreamer * This)¶

C++11: bool stop()¶

Traditional C++: bool stop()¶

Java: public native boolean stop()¶

Objective-C: - (bool)stop¶

Swift (since EasyAR SDK 2.1.0): public override func stop() -> Bool¶
