Hi!

the wrapper works great!
But seems runing holisitic got some issue, the pose tracking not working, it was stucked at first frame.

Can u help me out? I have sent you an email, thanks so much!

My best guess is that you need to clear the queue of the pose output stream. For example, in this repository's face mesh example, I don't just grab the next packet available in the multi_face_landmarks output stream. Instead, I clear the queue until it is empty:

libmp-example/main.cpp

Lines 29 to 38 in d682b12

	// I use a unique_ptr for convenience, so that DeletePacket is called automatically
	// You could also manage deletion yourself, manually:
	// const void* packet = face_mesh->GetOutputPacket("multi_face_landmarks");
	// mediapipe::LibMP::DeletePacket(packet);
	std::unique_ptr<const void, decltype(&mediapipe::LibMP::DeletePacket)> lm_packet_ptr(nullptr, mediapipe::LibMP::DeletePacket);
	// Keep getting packets from queue until empty
	while (face_mesh->GetOutputQueueSize("multi_face_landmarks") > 0) {
	lm_packet_ptr.reset(face_mesh->GetOutputPacket("multi_face_landmarks"));
	}

Remember that if you don't use a smart pointer, then you have to delete packets yourself, otherwise they will stay in memory.
