Python 2 reached upstream end-of-life in January 2020. In Fedora Rawhide, it's now provided from the compat package `python27`. Packages that only use Python 2 at build time, like gstreamer1-plugins-good, had a general exception to keep using it in Fedora 31. Now, the dependency should be removed. Switching to Python 3 seemed easy to me (though I don't necessarily know much about gstreamer1-plugins-good). So I opened a pull request: https://src.fedoraproject.org/rpms/gstreamer1-plugins-good/pull-request/2 Could you merge it? If not, if it's possible that the Python 2 build dependency won't get removed in Fedora 33, please let us know; the package will need a FESCo exception. If you need anything from us, or something is unclear, please mention it here.
The BR was removed in: https://src.fedoraproject.org/rpms/gstreamer1-plugins-good/c/b31fc6c9454b14eaf00ad78bb951d0f27264b749?branch=master Thank you!
