Interactive Video

Hello all,

I am facing a strange problem with the H5P plugin for Moodle, specifically the "Interactive Video".
I have embedded some video into a course via this content type (as .mp4).

Via Edge (version 112.0.1722.58 (Official Build) (64-bit) (my default browser), the videos play flawlessly embedded in our learning platform.
But now I get the user message that after clicking on a video tile in the video player, the following error message appears when calling it via Firefox:

"Unable to decode media."

1. Detailed steps to reproduce the bug (exactly how and when did it happen)
   Open the video https://h5p.org/node/346910 on any browser on an iPad, redirect to Youtube suggested.
   
   Open the video on Android or Windows, and the video will play flawlessly.
2. Platform and version number. E.g. Drupal, Wordpress, Moodle.
   iOS 16.4.2
3. Mobile or Desktop
   Mobile/ Tablet
4. Browser: Chrome, Firefox, Safari etc
   Chrome, Safari and Firefox (only on iPad)
5. H5P plugin version

Dear All

I have created an H5P Interactive Video where the video is hosted on Youtube.  What is the load on the Moodle Server when students access the content, view the video and answer the quesions?  As I understand it the content will stream the video from YouTube, add the interactive layer and present it to the student without the video stream having anything to do with the Moodle server - am I correct?

Having the video somewhere else must make a HUGE difference in the load on the Moodle server?
