Description

Receives frame updates from a nap::CVCaptureDevice on the main application thread. The actual capture operation is handled by the nap::CVCaptureDevice on a background thread. Register to the 'frameReceived' signal to receive frame updates on the main processing thread.

Note that the frame that is forwarded to potential listeners is a reference. Do not modify the content of the frame! Changes will be forwarded to other listeners. To get an actual copy of the content of the frame call FrameEvent::clone(). Do this before performing any operation on the frame itself.
