Bug ID: 356348
Summary: HEVC Videos Not Showing in Preview Mode
Product: dolphin
Version: 4.14.2
Platform: Mint (Ubuntu based)
OS: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: view-engine: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: phillip9...@juno.com
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.
