Plugins installed: mplayerthumbs, ffmpegthumbs, kffpmegthumbnailer, kdegraphics-thumbnailers, ffmpegthumbnailer. The thumbnail previews of various container videos (e.g., flv, mpeg, mkv, and avi) in dolphin do appear, when "Preview" mode is active or when you mouse over the files. However, with HEVC (high efficiency video codec) video files the previews do not appear on the files nor when you mouse over the icons. In the preview panel, you can still play the HEVC video files without any hindrances, but the preview thumbnails or icons are still missing in Preview panel. Reproducible: Always Steps to Reproduce: 1. Install the following plugins/codecs: mplayerthumbs, ffmpegthumbs, kffpmegthumbnailer, kdegraphics-thumbnailers, and ffmpegthumbnailer. 2. Activate the plugins/codecs in the "Settings" tab and under "Preferences". 3. View HEVC video files in the local drives (via Dolphin 4.14.2), with "Preview" and "Preview Panel" activated. Actual Results: The thumbnail previews of various container videos (e.g., flv, mpeg, mkv, and avi) in dolphin do show even when you mouse over the files. However, with HEVC (high efficiency video codec) video files the previews do not appear on the files nor when you mouse over the icons. In the preview panel, you can still play the HEVC video files without any hindrances. I'm just curious if I'm missing any plugins or codecs that is necessary to view HEVC video file thumbnails and previews. If not, then it might be a bug or missing feature which I think should be remedied now that HEVC is starting to become more common. If you need more information or require anything on my end, please don't hesitate to ask.

Which mime type or file extension do these unsupported files have?
Maybe - Libraries don't support HEVC ? A quick test - with an older Ubuntu: $ lsb_release -a Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty $ kde4-config --version Qt: 4.8.6 KDE Development Platform: 4.13.3 Standard Ubuntu repository thumbnailer - using libav $ apt-cache policy ffmpegthumbs ffmpegthumbs: Installed: 4:4.13.3-0ubuntu0.1 Candidate: 4:4.13.3-0ubuntu0.1 Local build - using ffmpeg - not Ubuntu repository libav $ apt-cache policy kde-thumbnailer-ffmpeg-real-thumbs-mattepaint kde-thumbnailer-ffmpeg-real-thumbs-mattepaint: Installed: 0.4~trusty~ppa3 Candidate: 0.4~trusty~ppa3 Sample file: https://x265.com/hevc-video-files/ -> https://s3.amazonaws.com/x265.org/video/Tears_400_x265.mp4 The stamdard Ubuntu repository thumbnailer: http://imgur.com/KWy29Gl Local build: http://imgur.com/BNT6pCp Maybe - Libraries are too old, don't support HEVC ?
(In reply to Christoph Feck from comment #2) > Which mime type or file extension do these unsupported files have? The HEVC files are both mp4 and mkv containers. I hope that is what you were referring to. Let me know if you need anymore information.

I take it that KDE 4.14.2 doesn't have the necessary libraries to preview HEVC in dolphin? Does that mean I should update my libraries or try updating KDE Plasma 4 to Plasma 5? Does this problem occur in KDE Plasma 5?

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
