It looks like libheif now supports a plugin architecture, so we could move libheif to Fedora, while having the HEVC/H.265 backend plugin in RPM Fusion. Also, according to the CMake, the HEVC/H.265 plugins are not built by default anymore: https://github.com/strukturag/libheif/blob/cdcc5b210879e0a0348032a594f8be52bb739c0d/CMakeLists.txt#L92-L98 So feel free to package it and bring it into Fedora. :) -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ 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
