Recently I'm working on build RPM package for `X265` project in openEuler Upstream. X265[1] is an opensource library about H.265/HEVC video encoder application.

    While when I try to create the repo in openEuler, after a quick scan, I don't know which sig that X265 should belong to. Can you give me any suggestion? Which sig is the right place, or do I need to create a new one?
