@akavel no problem and I understand (I can imagine). @shashlick thanks for that. Very useful.
I have left my spaguetty code [here](https://github.com/mantielero/h2nim.py) (I called it **h2nim.py** ). It uses [pyclibrary](https://pyclibrary.readthedocs.io/en/latest/) under the hood. It is far from perfect (it is not aiming to), but it is under 500LOC, so it is easy to tweak to particular needs. It might help others wrapping easy libraries. It helped me with VapourSynth because of this [issue](https://github.com/nimterop/nimterop/issues/137) I filed in nimterop and with GR.
