using	pull_free_image_cb_t = std::function<bool(std::shared_ptr<img_t> &img_out)>
	Get free image from pool. Calls must be synchronized. Blocks until there is free image in the pool or capture is interrupted.

using	push_captured_image_cb_t = std::function<bool(std::shared_ptr<img_t> &&img, bool frame_captured)>
	Callback for when a new image is ready. When display has a new image ready or a timeout occurs, this callback will be called with the image. If a frame was captured, frame_captured will be true. If a timeout occurred, it will be false.

Parameters

pull_free_image_cb	call this to get a new free image from the video subsystem.
img_out	the captured frame is returned here
timeout	how long to wait for the next frame
cursor_visible	whether to capture the cursor
