0.98.0: Video thumbnails not working
Posted: Wed Dec 30, 2020 3:41 pm

XnView: MP 0.98.0 - 64 bit
OS: Windows 10 20H2 64bit
In the file list pane, video thumbnails are not being generated. In the settings it's set to generate 4 images, just like for folders. Switching that to 1 image does not solve it.
Effect: All I see it the system icon in place of the thumbnail. Same icon as in details view, but bigger.
To reproduce:
No idea, mate. Just go to a folder with videos and be in thumbnail view?
Actual behaviour (bug): No thumbnails for video
Expected behaviour: Opposite of actual behaviour.
Additional context:
This is the case for at least MP4 and WEBM files. I have not tested any other videos, as I don't have other files handy right now.
It might be helpful to know that this issue existed on 0.97.1 as well (at least - I can't be sure for older versions). I updated just to see if it happens to have been fixed.

Ah, and there it was. Thumbnails were disabled there.
Honestly, I do find that a weird place to enable/disable thumbnails, since there's a dedicated "thumbnails" section in the settings...
/edit
Oh, it crashes in some folders with those thumbnails enabled. No error message or anything, just *poof* and XnView is gone.
Even though all videos play just fine.
This might be why I disabled it, until it's got the bugs ironed out.

Same problem here.

XnView MP Linux

The first video metadata read ok, but for the second, it crashed:

Sorry, but how did you get those logs (I assume they are) on a crash?
For me XnView is jut *poof* and gone completely.

I returned to use XnView.
With Version 1.4.5 64bits (May 10 2023) it is working.
