STEPS TO REPRODUCE
1. Browsing searches in Tabel-Thumbnails view.
2. On time Similiarity also Not Responding.
3.

The Table view is more problematic

great performance improvement to the table view
Almost no freezing of the table view when
scrolling a large view with > 30000 items.
Updating an entire row is faster than updating
a table element when updating thumbnails.

Comment 5 Maik Qualmann 2021-04-21 06:14:17 UTC

The table view is not as fast as the thumbnail view. It needs optimization in sorting and in the model code. But I cannot reproduce a general problem. From what number of items in the table view does the problem arise for you? A DebugView log might also help, as described here:

Comment 7 HJ 2021-04-21 08:06:13 UTC

I have 92000 image and video files.

Comment 8 Maik Qualmann 2021-04-21 08:11:27 UTC

They are very strange error messages. Also, it is not normal that from the video files cannot be create thumbnails. You are sure that your hard drive has no errors or reading problems? That would explain the freeze.

Comment 9 HJ 2021-04-21 09:00:18 UTC

"Cannot create thumbnail for ..." are broken files?

Comment 10 caulier.gilles 2021-04-21 09:09:08 UTC

Hi,

For ex:

[11448] digikam.general: Thumbnail is null for  "D:/MEEDIA/My Videos/Panasonic
video/VIDEO_TS/MP4/MVI_2898_x264.mp4"

The path include space. It can be a problem, but i'm not sure.

Can you try to take a video file in your D:/ in a path not including space. Just for testing ?

MVI 2774 _x264.mp4 is a broken or file without a video codec.
This is a remnant of a program experiment.
The VIDEO_TS.VOB file works with the VIDEO_TS.IFO file and contains a video dvd menu image.

Comment 13 Maik Qualmann 2021-04-21 10:43:02 UTC

The message "Cannot set Iptc tag string into image using Exiv2" could also come from Exif, I have adjusted the error message. We will see it with the next Windows version.

Comment 14 Maik Qualmann 2021-04-21 10:45:13 UTC

Another thing, you haven't set the debug environment variable with the Windows environment variable editor at the moment, as described on the digiKam page. Can you post the error messages again with the debug variable activated? Then digiKam becomes even more talkative.

Comment 22 Maik Qualmann 2021-04-22 19:25:16 UTC

Your search returns 92028 items that will take some time in the table view before they are displayed. Use the thumbnail view, this is already more optimized. I never use the table view myself. However, you have strange waiting times in the logs, I definitely suspect that you have a hard drive problem.
