Well not two different package managers but just two repos from different people (so hard to keep deps in sync). Packman (the third party codec repo for openSUSE) is slower to update compared to official repos, which often results in a situation where a thing from Packman requires a different version of a library than stuff from official openSUSE repos. But in that case it is easy to solve (for the user) in that you'll just have to wait a bit for Packman people to figure out the situation.
