Issue uploading more than 2 videos on Xibo Docker 4.2.3

[0x0]

@DanBW,

First lead is tn_* named thumbnails from here:

@dan

The thumbnails for each library image are only generated once when first requested - after that they are saved to the library folder in the format tn_<mediaId>.<media ext>

I have tried to delete all thumbnail tn_* files from CMS library in hope reboot will play smart and automagickly regenerate all missing thumbnails on new start …

Looking at file date it seems that it did regenerate all tn_* files but failed with same bug as in thumbnails for videos are scrambled, pictures seems to work…

Files regenearated on date and time is set to 18:08-18:12:

Video thumbnail broken:

Image thumbnail works:

Second lead is script which is generating thumbnail:

Thumbnail Display Issue v3.1+

I’ve only checked 3.3.8 as that’s the current v3 release, but it does indeed cache that in the CMS library when the thumbnail is generated the first time. That’s the function. That’s where it’s checking if the file already exists. You’d see those in the CMS library directory as files starting with tn_.
