Any plans regarding this ITP? Are you planning to upload the package to debian/non-free at some point?
I see you are providing packages on you own apt tree. The packages there are currently uninstallable in bookworm and seem to be blocking upgrades of libavcodec59 and libavutils57. Dependency issue seems to be with libmakemkv1: Depends: libavcodec59 (= 7:5.1.3-1), libavutil57 (>= 7:5.1) -- Samuli Suonpää, toimittaja
