Created attachment 206704 [details] https://github.com/dirkvdb/ffmpegthumbnailer/pull/149 ffmpegthumbnailer master branch has a patch to correctly rotate videos that have been flipped 180°. The v2.2.0 release only correctly handles videos that have been rotated 90° clockwise or counter-clockwise.
I don't use FreeBSD as a desktop system and hence I can't test it and apply patches. The transition to different maintainer is the best option for this case.
fwiw I also don't use freebsd on the desktop, but do use ffmpegthumbnailer on server commandline.
Thank you for the report and patch Mark @Maintainer Did you want the MAINTAINER'ship reset entirely for this port, or did you want to just forego testing/verification for this specific issue only?
(In reply to Kubilay Kocak from comment #3) I'd prefer the MAINTAINER'ship reset entirely for this port

I have reset maintainership. To submitter: would you agree to take on maintainership for this port?
Sure, I'd be happy to take on maintainership.
