Hello Rémi,
to be here on the save site, I made now a small qt app where I have my player running in, so I'm sure nothing from the rest of the app is producing this problem.
I also added a button what is calling libvlc_release(instance).
Ii get still the same result, with each start of the video the memory of the app is increasing (start was at 8MB, after first start it wenup to 50MB ) by around 1MB, when I push the button to delete the instance the memory is not really going down (perhaps 500k)
