Preview thumbs for mp4 not generated with PHP 8.0 and non-latin path to mp4 files.
With PHP 7.4 all ok.

error log:

The correct path to file VID_20211122_185857.mp4 is:
/var/files/nextcloud/Siava/files/Автозагрузка/Мои фото/2021/11/VID_20211122_185857.mp4

Is it Nextcloud problem or my server software?

The same happens in my case. Also there is another topic on forum with the same problem.
Have you find any solutions?

I found problem in lib/private/Preview/Movie.php

escapeshellarg($absPath)
for non-latin path makes path wrong (strips characters).

Adding this string to config.php helps me:
setlocale(LC_CTYPE, "ru_RU.UTF-8");

Then this is a problem of my server… maybe setting the locale will helps.

Thanks much!
The solution works for me too.

This line was auto-deleted from config.php few time after…
So I added this after beginning of
private function generateThumbNail($maxX, $maxY, $absPath, $second): ?IImage {
in lib/private/Preview/Movie.php

Thanks much.

That solution also worked even after rebooting. Unfortunately, the error continues in the logging, but at least preview works.
