That the fedora mesa package completely drops the vaapi backend, so a complementary package can just drop the missing files instead of rebuilding a whole mesa package. It would assume the fedora mesa package to have everything needed in order to cope with vaapi backend enabled in the core libraries and that the vaapi backend only provide the implementation. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
