Nothing really comes to mind - my builds should be reproducible. I assume DVD playback has worked before with your own builds?

Possibly some build host dependency is missing - have a look at how Kodi is building, search for "DLIBDVDNAV_URL" and what path is it using? These are my DVD-related build settings:

Code:

...-DENABLE_DVDCSS=ON -DLIBDVDCSS_URL=/home/neil/projects/LibreELEC.tv/sources/libdvdcss/libdvdcss-2f12236.tar.gz -DLIBDVDNAV_URL=/home/neil/projects/LibreELEC.tv/sources/libdvdnav/libdvdnav-43b5f81.tar.gz -DLIBDVDREAD_URL=/home/neil/projects/LibreELEC.tv/sources/libdvdread/libdvdread-17d99db.tar.gz

Yours should be similar.     

DVD playback always worked before, it stopped working just recently.
I don't see anything obviously suspicious. libdvdcss, libdvdnav and libdvdread are the correct versions.
I did another clean build and it still does not work. Debug log
