Thank you for your bug report, is there any chance you could add a short video example to the bug (or give an url to download one)?
It's probably a bug in totem, does it has the same issue if you do $ totem-video-thumbnailer somevideo.mkv bug.png then look at the generated image? ** Package changed: nautilus (Ubuntu) => totem (Ubuntu) ** Changed in: totem (Ubuntu) Importance: Undecided => Low ** Changed in: totem (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1818623 Title: Thumbnails have weird purple tint on HEVC MKV files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1818623/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
