Description andrejkassovick.16 2024-08-14 18:23:36 UTC
Good morning. The same problem as always returns in this version 23.08. When updating Ubuntu from 22.04 to 24.04, the video thumbnail views disappear and the previous video folder views are not seen either.
 Can the previous version be downloaded? I had an old version installed on Ubuntu 22.04, which worked perfectly, but when I updated it uninstalled it.
Comment 1 Akseli Lahtinen 2024-08-20 08:25:25 UTC
Couple questions:

- Does pressing F12 to toggle the previews on and off solve issue?
- Can you see any other previews, like images?
- Going to "configure dolphin" menu (default shortcut should be Ctrl+Shift+,) and in "Interface" section selecting "Previews" tab, is video files enabled?

Good morning. F12 does nothing. Previews of images are visible and of any
other type of file. NOT VIDEO. In Dolphin configuration NO BOX APPEARS TO
ACTIVATE VIDEO PREVIEWS. I know that in old versions there was. I hope for
a solution. Thank you.

Hi, the last message you received was because I added myself to the cc list for this bug. That's why there was no other message. Please be patient, we will respond to you when we have more information.

Good morning. Well, the issue is very simple. Video thumbnails and video
previews are not visible in the folder, at least on secondary drives. Image
views are visible in both cases.

In previous versions there was the possibility of configuring Dolphin to
see them, but not in this new one.

Hello. What do you need more information about? The thumbnails and folder
previews of videos are not displayed in this version of Dolphin. There is
no way to configure it, since this option does not appear, which was the
case in previous versions. The screenshots I sent show what I am saying. Let's
see if it is fixed once and for all, or if there is some trick I can do to
recover both options, because it is taking me forever to do my daily
work. Nothing
more, I am waiting for news.

Comment 11 Akseli Lahtinen 2024-11-06 23:42:10 UTC
Hi, I set it from "needsinfo" to "reported" so that the bug wont be automatically closed.

Now that I remember, one thing you could try though is that pressing F12 in dolphin toggles the previews on and off. 
Can you give that a try and report back here, if it helps at all?

Hi. I already said it in a previous message. F12 is useless. Is there
anything else I can do? I await your reply.

Comment 13 Justin Zobel 2025-02-08 00:40:59 UTC
Can you please check that the ffmpegthumbs package is installed? Perhaps the upgrade removed it for some reason. You can do this by opening up a terminal and running 'sudo apt install ffmpegthumbs'. It will install or tell you it is already installed.

Yes, the package is installed, but the thumbnail previews of the video
files are still not displayed.

Comment 15 TraceyC 2025-02-10 17:40:33 UTC
I am not able to reproduce this bug on Plasma 6.2.5 with Dolphin 24.12.1 (on Solus) or Dolphin 23.08.5 (Kubuntu 24.04)
I see a preview on a folder with mp4 files and for the file itself 
View - show previews - checked
If I uncheck that, they disappear as expected

To try to get more information about the issue on your system, can you run Dolphin from terminal and reproduce the problem?

From command line just run

dolphin

Then navigate to your mp4 folder
Then paste the output into a comment in this report. Thanks!

Comment 18 TraceyC 2025-02-10 21:53:14 UTC
I see your new attachments with new screenshots. That's not what I'm asking for.
After you run `dolphin` in your terminal, there should be some text output in your terminal
Can you open the folders and then copy and paste the text from your terminal application where you have run dolphin?

Thanks!
Comment 19 TraceyC 2025-02-11 02:32:11 UTC
Can I also ask you how to look at Dolphin in Discover and tell me how it was installed? Mainly, I need to know if it's a snap or not. Run this in a terminal, and let me know if dolphin is in this list:

snap list

Thanks!

Good morning. I've had trouble replying. To comment 18: do you mean all the
text that appears in the terminal?:
name:      dolphin
summary:   File Manager
publisher: KDE✓
store-url: https://snapcraft.io/dolphin
license:   unset
description: |
  Dolphin is KDE's file manager that lets you navigate and browse the
  contents of your hard drives, USB sticks, SD cards, and more. Creating,
  moving, or deleting files and folders is simple and fast.

  Dolphin contains plenty of productivity features that will save you time.
  The multiple tabs and split view features allow navigating multiple
folders
  at the same time, and you can easily drag and drop files between views to
  move or copy them. Dolphin's right-click menu provides with many quick
  actions that let you compress, share, and duplicate files, among many
other
  things. You can also add your own custom actions.

  Dolphin is very lightweight, but at the same time, you can adapt it to
your
  specific needs. This means that you can carry out your file management
  exactly the way you want to. Dolphin supports three different view modes:
a
  classic grid view of all the files, a more detailed view, and a tree view.
  You can also configure most of Dolphin's behavior.

  Dolphin can display files and folders from many Internet cloud services
and
  other remote machines as if they were right there on your desktop.

  Dolphin also comes with an integrated terminal that allows you to run
  commands on the current folder. You can extend the capabilities of Dolphin
  even further with powerful plugins to adapt it to your workflow. You can
  use the git integration plugin to interact with git repositories, or the
  Nextcloud plugin to synchronize your files online, and much more.
commands:
  - dolphin
And from there I sent it to you.

I don't have Google or any of its variants or apps installed. I use Firefox
and open source variables. This appears in the snap list:

Comment 22 TraceyC 2025-02-18 22:19:03 UTC
Thanks for the additional detail.
From the output, Dolphin is indeed installed as a snap.

I'll let someone more knowledgeable about Dolphin take it from here.
Comment 23 Justin Zobel 2025-02-19 00:55:14 UTC
Adding Scarlett as this is a snap issue.
