It is not the KDE libraries - It is the libav/ffmpeg libraries. Short : The Debian & Ubuntu decided to use the ffmpeg fork libav /1/. The Ubuntu 14.04 is using libav 9.18 /2/. Ubuntu has a stable release policy /3/ to not update old packages. There will be bug fixes for the serious bugs. When I was using the Ubuntu 14.04 I added the HEVC support to the KDE thumbnailer by: - compiling an own local version of the current ffmpeg - rebuilding the ffmpegthumbs so it is using the local ffmpeg not the distro libav. By my knowledge the Mint /4/ is using the Ubuntu packages but I don't know witch version is using the newest released version. With the Ubuntu KF5 thumbnailer there is the bug: https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/1505014 1. https://www.kubuntuforums.net/showthread.php?62882-Avconv-Winff-ffmpeg 2. http://packages.ubuntu.com/source/trusty-updates/libav 3. https://wiki.ubuntu.com/StableReleaseUpdates 4. https://en.wikipedia.org/wiki/Linux_Mint -- You are receiving this mail because: You are watching all bug changes.
