Trying to get qtVlm to run on Raspberry Pi 4 with a debian install

I downloaded the raspberry pi buster version, and initially I had a "cannot find shared object file: libpulseaudio", so I installed that, but the one I'm struggling with is the next error which is :-

"cannot open shared object file: libmd4c.so.6"

Any ideas ?

Thanks

We provide for rpi4 raspbian 32 or Debian 64 build both based on bullseye.

Older system should take the other 32 build
