Video.cs on a Docker install ? Open not called after 4 sec error

Hi Xibo Team.

I encountered an issue very common : “MediaElement_loaded : Open not called after 4 secs, marking unsafe and skipping”.

It happend so many i’m driving mad about it.

I’ve found the solution for a dotnet client installation : Video failed: Open not called after 4 seconds

But the Dockers installation is not the same. I am a newbie in this case and i’ve failed to find this directory in my docker who look like this :
opt
xibo
shared
backup
cms
ca-certs
custom
library
locale
web
theme
userscripts
db

Discuting with AI recommand me to create the video.cs file and call it ?

Any idea ?

Thanks for your answer,

Jean
