Videoplayer: Error loading filename.mp4

I had just finished setting up nextcloud, when I faced this problem. When I try to watch videos from my server on the web gui, videoplayer just displays: Error loading filename.mp4 (same error with .mov videos). Some mp4 and mov videos however play correctly. I have tried to scan all files with occ files:scan --all , but that isn’t helping. I also checked file permissions on the server and they should be right…

In the server log there are two errors like this, but I am not sure if they are related to the problem I am facing:


0. /var/www/html/nextcloud/apps/text/lib/Service/DocumentService.php - line 324:OCA\Text\Service\DocumentService->getFileById(1469, "admin")

How could I fix this problem?

I have enabled:
APCu for local caching,
Redis for filelocking and distributed caching,
and OPCache.

Videoplayer cannot play videos if there are some special characters in the path. (ä, å, é, #…)

I wouldn’t say this is solved… can we get this rather fixed in the video-player plugin itself? Unfortunately I cannot modify some file names :confused:

Thx, Michal

For me it is working as a good workaround as I manage paths and filenames.
Thanks to everyone.

Hello guys.

Is there a specific solution for this issue?

I have the same problem and I also changed the special characters of the video title.

Used docker to download these apps/containers. All from the Linux server.

I’m very new to this and thanks in advance.
