OBS is both a software and the openSUSE official build instance.
Packman uses OBS (software) on a separate build instance called Packman Build Service (PMBS), which publishes packages under a host where SUSE can not be held accountable.
My question was clumsy - I really wanted to know why PACKMAN can provide x264/x265 and suse can’t. Does PACKMAN have some sort of license that suse doesn’t?
