Those all have dependencies on various other packages in the libav
family. libavdevice?? seems more fundamental but gives me a surprising

# rpm -e --test libavdevice56
# rpm -e --test libavdevice57
error: Failed dependencies:

# rpm -e --test libavdevice58

As far as I can see, libavformat56 and friends are not used by
anything. 57 is used by a lot of stuff and 58 is also used by some
things, but for some reason they don't use libavdevice58.

Does that sound plausible?

So I can delete the *56 packages in the correct order.

Thanks again, Dave
