This did it. Thanks ! I apologize for the noise : I was fairly certain that my misguided attempt to use Marillat's package had been thoroughly cleaned. It was *not : charpent@brique:~/Vidéos/Établi$ dpkg -l "*" | grep "\-dmo" | sed -re "s/[ \t]+/ /g" | cut -f 2 -d " " | sed -re "s/:amd64//g" | xargs echo libaom-dev libaom3 libaribb24-0t64 libass9 libcdio19t64 libchromaprint1 libcue2 libdav1d-dev libdav1d7 libdca0 libdvbpsi10 libdvdcss-dev libdvdcss2 libebml5 libvmaf-dev libvmaf3 Downloading (manually !) the current trixie versions, deleting libvmaf* and libdvdcss* and reconfiguring libdvd-pkg did the trick.
