Several software products in the video stack are dynamically linked with ffmpeg, but likely need small-scale changes to run video ‘stuff’ correctly with the new 8.1 version.
And so, when you run ‘zypper dup’ with the possibility of upgrading all the packman packages to 8.1, it wants to add in the Opensuse 8.0.1 ‘mini’ library to assure that an 8.0.1 version is still present.
At this time, if you feel a need to stay with Packman because you need to use some of the newer and better codecs which were excluded from the Opensuse ‘mini’ library because of possible legal risks, you can click through the resolver options concerning the duplicated codecs to ‘keep the obsolete’ packman package in each case. Your packman will stay on 8.0.1, but with all the “bad” and “ugly” codecs still available.
Or, if you anticipate running multiple dist upgades before it the linked pacjkages get fixed and tested in QA, you can add locks on the packman 8.0.1 packages to spend less time typing with command-line zypper’s seven or eight 'resolver 'complaints.
The choice I would NOT make, myself, is allowing installation of the smaller Opensuse 8.0.1 “mini” package to link with all the Opensuse graphics packages. (As you saw, that would provoke about 27 “issues” instead of just seven “issues” where can keep your “obsolete” packman versions.) You would have an 8.1 Packman version in place, but it wouldn’t be working with the video stack for most things.
