1

I installed xibo CMS version 1.7 … and the xibo client same version on my computer, until then everything works well
but when I installed xibo client on other computers, videos do not show on other computers

Presumably that’s 1.7.9 CMS and Windows players in 1.7.9?

What Windows versions do you have on those PCs that have problems displaying the videos?
In what format and encoding are those videos please?
Are you able to play them in the Windows Media Player on those PCs?

Windows 10 and windows 7
the videos are in .mp4 format, and I can play the videos of such format on Windows media player
