in this case we need to
- apply the Kodi-specific patches, or
- switch libdvd* upstream to the Kodi repos
The packages were all forked by Kodi:
https://github.com/xbmc/libdvdnav/commits/master
https://github.com/xbmc/libdvdread/commits/master
https://github.com/xbmc/libdvdcss/commits/master
to add functions for supporting iso images by their internal VFS
implementation, for example dvdnav_get_vm:
https://github.com/xbmc/xbmc/search?utf8=%E2%9C%93&q=dvdnav_get_vm
This function is not defined in upstream libdvdnav, but added by
https://github.com/xbmc/libdvdnav/commit/8305696be79fe650d3d9eee29b2a88e020d7
c58f, guarded with ifdef _XBMC...
You can however link kodi.bin successfully with an unpatched libdvdnav, but
be warned: Kodi will crash during runtime like this:

to provide the libdvd* source to be compiled during Kodi build. With them I
can play iso dvd images without problems.

This week I switched my production system to a CMake-build Kodi created by
buildroot so the next iteration of my patch series is not far away :)
