I’m using xibo server (version 4.2.3) with players (version 4.0.5) installed in Windows 11 stations.
I was testing a new layout, and after finishing and checking it with the preview options, I published it, but to my surprise the player refused to open the layout with a message that it was invalid.
After many tests, I fund that the problem was a .PNG file that was very large (2480x3508). In the admin page the PNG displayed fine, in the preview too, but the player itself refused to open the layout with the image. I then resized this image to a smaller size (848x1200) and with that the player worked fine.
The layout for this test had only another .PNG file (sized 1080x1348) and nothing else.
So, is that a bug in the (windows) player? Or should the preview option have warned me that the image was too large?
I ran into this exact issue in my own Xibo CMS environment. The root cause turned out to be a misconfigured XTR, which meant that the Image Processing failed to run.
As a result, any layout containing images larger than 1920x1080 pixels couldn’t be processed and the players assigned to those layouts would refuse to play them entirely. On the other hand, layouts using images smaller than or equal to 1920x1080 worked fine as those didn’t require additional processing.
To help you further, It will be useful knowing the following:
Are you running Xibo CMS using Docker, or a custom setup?
Can you confirm whether the Image Processing task is active?
You can check this by going to: Tasks → Image Processing
If you find that the Image Processing task isn’t running, a temporary workaround is to manually resize your images to a width of 1920 pixels or 1920x1080 pixels before uploading them.
In the case you are using Xibo CMS with Apache II, you may find my earlier post helpful. It explains the steps to configure XTR properly: Cron Job not Working - #6 by MrStefan
Indeed i had not installed the cronjob, which would explain my problem. Unfortunately, I can’t make it work because there is some problem with the ZeroMQ repository (apt reports “404 Not Found [IP: 2620:2d:4000:1::81 443]” when trying to add it), so I can’t get it to work. I will try again later and report my findings.
Scratch that. While I was writing the last message the job worked (I had added it to cron…), the windows player downloaded the layout and accepted it. It’s working. So it was indeed the missing cron job.
