I use Moodle 3.4.
I put a video in a page activity.
With Moodle mobile it works, with a PC computer it works also (tested on Chrome and Firefox).
But in a mobile browser (Chrome and Firefox) it does not work (I have some black instead of the video).
I tried several players, but it is not that problem.
Does the HTML code has to be modified to make it compatible with the browser of a mobile device ?
Thanks in advance !
