Typically no.

I recommend to stop digiKam and drop the thumbnail-digikam.db file and restart
it.

Force to rebuild thumbnails with F5 key when you are in album with video. This
fix the problem ?

I had Digi closed deleted the thumbnail-digikam.db and started Digi. I hit F5
and it rebuild the thumbnails in a few mins. Everything flashed and then still
only gray video boxes.

Ok,

I suspect a possible ffmpeg codec missing for your video.

Can you share some video sample through the cloud to reproduce the problem ?

Can you install debugview program and run digiKam to press F5 in a video album
? debugview will capture all debug statements from digiKam. Se  this page for
details :

These are the codecs I have installed:
https://www.codecguide.com/download_kl.htm
The mega version and updated.

I will look into sharing some video sample through the cloud to reproduce the
problem. However I believe it is a shear numbers problem as sometimes a few
thumbnails load, even up to 20-30 videos show thumbnails. As soon as I scroll,
they flip back to gray. Not a particular video in the group that is causing the
issue.

Here is the output from debugview:
I edited path name and video locations for privacy reasons. Also this is a snip
it of starting digi cam, with thumbnail data base removed, and after hitting
F5. For each video file it simply repeats making a very large file where the
only thing different is the file name.

Let me know if you have trouble viewing that pastebin and I will copy the text
here.

No. Your codecs that you have installed are not used by digiKam

We compile ffmpeg codecs for QtAV player used in digiKam.

This kind of error is explicit :

avcore\npsm\localprovider\baseprovider\lib\baseprovider.cpp(604)\NPSMDesktopProvider.dll!00007FFA59332140:
(caller: 00007FFA593326E5) ReturnHr(497) tid(2de8) 80070490 Element not found.  

It miss a codec for your video. avcore come from libav codecs into ffmpeg.

Which kind of video type you use exactly ?

The file video file types are various, avi, flv, mov, mp4, wmv, and more... A
big mix.

Sorry, I do have those errors as well, I thought they were part of a different
problem I am having with Oculus Rift cameras because they occur at about the
same time.

The codecs are in digiKam, included at compilation time.

There is no way for the moment to know which codecs are available. I know that
only GPL2 licensed codecs are installed. No GPL3 and no patented codecs are
compiled for legal reasons.
