The behaviour described in the bug report is either by design, or would be far too complex/time-consuming to be changed

Problem - Thumbnails view - MOV (and any video) files

Post by *monarch-lfv »

When the thumbnails view is turned on in the folder with the *.MOV files (video from any smartphone), the TCx64 is closed (crashed) without displaying any errors.
TCx32 don't closed, but at the same time thumbnails of *.MOV files do not display.
Same Error with MP4 files, may be and other formats of video files.

Unfortunately this isn't a bug I can fix - it seems to crash in the Explorer thumbnail handler (or a plugin) used to extract the thumbnails.
What you can try is:
1. Install better DirectShow filters like the LAV filters which are known to work well with Total Commander
or
2.Exclude the problem extensions from icon extraction via Explorer method:
Configuration - Options - Thumbnails, change
Use Explorer method
from
*.*
to
*.* | *.mov *.mp4
You will not get thumbnails for these files then.
or
3. Find a Lister plugin which can handle these files and install it, it takes precedence over the Explorer method.

1. This bug is manifested at the newly installed TC32,64. There are no plugins (clean). Default TC settings. Codec settings by default Windows.
Explorer perfectly displays all thumbnails of video files in the folder. The problem is manifested on Windows10 х64 and Windows7 х64.
An example for the test of such a video file by link:
https://cloud.mail.ru/public/zX6k/YBpDEtcsW

2. Nevertheless, I want to see thumbnails. :(

3. I don't known that plugin. Maybe someone will tell me. :)

Thanks for the test video. I have tried it on Windows 7 and 10 in VirtualBox without any additional codecs, and it didn't crash and showed up just fine.

Hmm, strange. I checked again - crashed. There might be something wrong with the codecs. I will look for the cause of the failure. In any case, thanks!

Since you are getting a Windows crash, you can use the tool Procdump to create a crash dump:
https://technet.microsoft.com/en-us/sysinternals/dd996900.aspx

1. Create new directory c:\dumps
2. Create a lnk file of procdump.exe or procdump64.exe (for 64-bit Windows)
in Total Commander with Ctrl+Shift+F5, e.g. procdump.lnk
3. Open the properties of the lnk file with Alt+Enter
4. Change the command from c:\path\procdump.exe to
"c:\path\procdump.exe" -ma -i c:\dumps
5. Important: Click on "Advanced" and check option "As administrator"
6. Run procdump with this link file
7. Wait until the crash occurs.
8. Send me the dump file from c:\dumps.

Alternatively to 8, you can analyze the report yourself with Windbg (made by Microsoft):
https://developer.microsoft.com/en-us/windows/hardware/download-windbg

Usage:
1. Create new directory c:\Symbols
2. Run Windbg
3. Menu File - Symbol search path, add the following:
srv*C:\SYMBOLS*http://msdl.microsoft.com/download/symbols
4. File - Open crash dump - choose the dmp file
5. Enter the following in the command line:
!analyze -v
(including the exclamation mark!) and press ENTER.
6. Wait
7. When the result is there, select all, press Ctrl+C and paste the result to the forum.

According to both dumps, the crash is in IcarosThumbnailProvider.dll calling swscale_ics_5.dll, which are both part of the K-Lite codec pack. The default installation directory is
%PROGRAMFILES%\K-Lite Codec Pack\Icaros

Try uninstalling K-Lite and install LAV filters instead:

K-Lite contains the newest LAV filters
and there are no crashes here with MOV files and TC thumbnails.
Also tested with the video from monarch-lfv'
My K-Lite is Standard version 17.0.5 with LAV Filters 0.76.1-3-ga6b20
May be he should update his K-Lite package.
Windows 11 Home x64 Version 23H2 (OS Build 22631.3374)

You right!
Really, 'K-Lite Codec Pack' is guilty. Unfortunately update to latest version k-lite did not help.
I uninstall it, and thumbnails began to show without any problem.
Then I Installed LAV filters for support video formats.
Problem solved. The only strange thing is that the explorer displayed thumbnails earlier, but the TC did not.
Thank You very much!

K-Lite contains more components than just the LAV filters. The problem library IcarosThumbnailProvider.dll isn't included in the LAV filters. There is no need for a separate thumbnail provider because once you have the right codecs installed, the default thumbnail provider can extract the thumbnails for Explorer and Total Commander.

Thats ony true if you don't need any of the thumbnails Icaros delivers
also one can configure what Icaros does.
Thumbnails are fast here and I not only use them in TC.
As I said no crashes with MOV files from Mobiles and also with the provided test file.
So I'm very happy with the K-Lite Standard package.

Of course you can keep using K-Lite as long as you don't have any crashes. Maybe it has troubles with one specific video codec or even an encoding format which causes the crash. If you don't have any such videos, you will not get any crash.

The thread provides a MOV video which crashes on the posters machine
but not for me !
