How do I enable video thumbnails in an earlier file manager, I was installed TOTEM program to do this, but this does not work now

Is there a solution  :?:  :?:  :?:

So which file manager do you use?
I think maybe any file managers don't have this function.

I use the file manager nautilus which comes default with deepin

Even I have used nautilus, nemo file managers. The thumbnails (for both photos and videos) are not generating. Please let us the method to generate thumbnails.

This issue has been reported to the bug tracker to see if it is considered a flaw: 0002466

I found it works well on my computer
