MarsSeed [1] filed a deletion request for ffmpeg-vp9-timestamp [2]: Orphaned package based on the legacy ffmpeg 4.4.1 package, backporting an as-yet unreleased patch from ffmpeg git master (after n5.1-dev). Build was reported failing 9 months ago but no one fixed the package. I believe this abandoned package is not useful to keep. It does not work and does not even declare its conflicts properly. I think if that specific unreleased patch was really important and urgent for the general user base, an Arch bug should be filed for such request. (But as of now, no one have done so.) (Or better yet: an ffmpeg ticket could be filed to get this backported to ffmpeg 4.4 and/or 5.0. But it seems that hasn't happened either.) So I see no point in keeping this package, broken, sans maintainer and without any indication that it is needed by anyone. Safe to delete; nothing on AUR specifically depends on this one.
