Video format not supported
Hi,
Suddenly most mp4 videos uploaded in H5P (Moodle 3.5.17 Build: 20210308) are no longer loading for students due to 'Video format not supported' error. The format is 'unknown' when looking at the source file in H5P as an administrator.
I cannot identify why embedded mp4-files gives the error "video format not supported" only when logged with the role 'student'. All videos load fine when logged in as an administrator. There are no issues with the video source URL. We've tested all browsers and couldn't see any difference.
