same here…

OS: TrueNAS-12.0-U2

add custom css plugin and write this:

.plyr__video-wrapper video {

right: 0px;
bottom: 0px;
min-width: 100%;
min-height: 100%;

I’ve got the same issue. Playing around with custom css surely can’t be more than a fast workaround, can it? It would be interesting to know what’s the cause of this and if it is in the pipeline to be fixed in one of the upcoming releases.

Hi, which NC version do you have installed?

Hi and thank you for your reply. My NC is of version 21.0.1.

Hm… This should actually be fixed with NC21.0.1 in

Ok, to confirm it, I just removed the custom css and the video showed up in the upper left corner of the screen only. Can I contribute with some logfiles / diagnostics or something?

On my macbook pro. The issue seems to persist with Safari browser. With Chorme the fullscreen is working for m4v files. My server is 21.0.1.
