BLACK SCREEN

I am experiencing a problem with YouTube videos when using the H5P Interactive Video content type in Lumi.

The issue started suddenly today. The exact same YouTube videos were working normally yesterday, but now the video area appears completely black.

The important details are:

• The YouTube video loads and plays.

• The audio works normally.

• The H5P interactions also work normally at the correct timestamps.

• However, the video image remains completely black during playback.

• The video duration is detected correctly.

• The same problem happens with different YouTube videos, not only one specific video.

• The YouTube videos themselves work perfectly when opened directly on YouTube; both video and audio are displayed normally.

• If I upload the original MP4 file directly from my computer into Lumi instead of using a YouTube URL, the video image displays correctly. Therefore, the problem seems specifically related to YouTube video embedding/playback inside H5P Interactive Video.

I also exported one of the affected projects as an .h5p file and uploaded it to my MoodleCloud course. The exact same issue occurs there:

• audio works,

• H5P interactions work,

• but the YouTube video image is black.

Even H5P activities that I created and uploaded yesterday, which were working correctly at that time, are now showing the same black screen in Moodle.

I have already tried the following troubleshooting steps:

• Restarted the computer.

• Tried Microsoft Edge.

• Tried Google Chrome.

• Created a new Lumi account.

• Created a completely new H5P Interactive Video project.

• Tested a different YouTube video URL.

• Tested older H5P projects that previously worked.

• Tested the YouTube video directly on YouTube, where it works normally.

• Tested uploading the MP4 file directly into Lumi, where it also works normally.

I also received an “Internal Error” message from Lumi shortly before this problem started.

Because the same issue occurs with multiple YouTube links, multiple browsers, a new Lumi account, and also after exporting the H5P file to Moodle, it appears that there may currently be an issue with YouTube playback or embedding inside H5P Interactive Video.

This is very important for my project because I am using YouTube as the video source to keep the H5P files small and avoid consuming a large amount of MoodleCloud storage.

Could you please let me know:

1. Is this a known issue currently affecting Lumi or H5P Interactive Video?

2. Is there a temporary workaround that still allows us to use YouTube URLs?

3. Is an update or fix currently being prepared?

4. Will existing H5P projects automatically work again once the issue is fixed, or will they need to be recreated or re-saved?
