Hi @massi-ang,  
I had a rather similar issue some time ago. When using OpenCv objects (images, matrices, ...), you need to clone those objects via the OpenCv cloning functions.

As you can see in [this](https://discourse.nodered.org/t/live-stream-about-pluggable-message-routing-some-questions/30508/12) old discussion, I have been experimenting with custom cloning. However due to free time constraints, I had to quit this. Keep in mind that it was a quick test, so it might be a bad design!!

It would be nice if cloning could somehow been customized in the future. But I assume this will probably not that easy, because it has to work in a lot of different scenarios. And it should be fast, because this code is being called all over the place.  
Bart
