mpvWrapper : a viewer plugin using mpv to preview video&audio

[bytim]

Mpv has the fastest startup speed and is the most suitable for previewing.
With mpv, You can preview various videos without installing a decoder such as K-Lite Codec / Shark007Codecs.

Download mpv from https://mpv.io/installation/.
https://github.com/mpv-player/mpv/releases
mpv-v0.xxxxx-x86_64-pc-windows-msvc.zip
https://github.com/shinchiro/mpv-winbuild-cmake/releases
mpv-x86_64-v3-xxxxxxxxxx.7z    → for Newer CPUs

thumbfast : a High-performance on-the-fly thumbnailer lua script for mpv.
Place thumbfast.lua into the path "mpv\portable_config\scripts\thumbfast.lua" .
(一个高性能的时间点缩略图脚本)

Download the appropriate version based on your language.
Place the dll into "/home\viewers" and restart DOpus.
2026.7.1 v1.1 : mpvWrapper_chs.zip (47.5 KB)
2026.7.1 v1.1 : mpvWrapper_en.zip (47.6 KB)

Preferences / Viewer / Plugins, show all plugins,
move mpvWrapper up, above the video&audio plugin. Or move it to the top.

The setting GUI, you can add extensions and edit the path of mpv.exe.
If the exe path is invalid, the preview action will be delegated to other plugins.
Environment variables, Dopus alias and absolute paths are all supported.

Very cool idea.
Notes:

• I guess it is better to use the official binaries from GitHub MPV-player releases. Use MSVC based builds like mpv-v0.41.0-x86_64-pc-windows-msvc.zip
• Do you consider sharing the source code of your viewer?

Thanks @bytim Great initiative and potential use case.

I haven't personally felt anything wrong with GPS own movie dll in terms of speed. Is this a common issue by people? Honest question as I don't really use the viewer for media like this.

Interested to know what others have come across.

To be honest, I don't know which compilation version is better.
After using it for a while and confirming that there are no serious bugs, I will release it on GitHub.

In the setting GUI, double-clicking a listview entry can directly open the editing map dialog.

MPV has a wide range of functions.

Thank you very much for sharing, will the potplayer preview be supported in the future?

[bytim]

potplayer starts relatively slowly, making it unsuitable as a previewer.

[fkast]

why this plugin prevents columns to work?

[Leo]

Try moving the Video & Audio plugin to the top (or the mpvWrapper plugin down, so it's after Video & Audio).

If you also configure the Video & Audio plugin and turn off all three Playback Methods, it should allow the mpvWrapper plugin to handle playback while still handling the columns itself.

(Edit: While in the Video & Audio plugin config, make sure MediaInfo is turned on under Metadata Methods. The Windows Shell option is off by default, and not usually beneficial on top of MediaInfo.)
