Consider running ldd `which HandBrakeCLI` | grep -i found which might show you which other libraries are missing. If it's only libass.so.5, potentially a symlink ln -s libass.so.9 libass.so.5 in /usr/lib64 would do the trick, but the difference in version numbers appears large. Maybe it matters, maybe not. I'd also try to update HandBrakeCLI ; a later version might make use of libass.so.9 . HTH, Kay
