Okay so I am having this issue where training videos that I upload to a youtube channel, when embedded in a Moodle lesson content page, get this dialogue box that says "no video with supported format or MIME type found". You cannot interact with it. But it doesn't do this to all of them. These videos have the same settings, etc. This happens when using Mozilla FireFox. If I open the same page in Chrome, instead of the dialogue box having that message, its just an empty video player box. If you click on that box, it will open a new tab to the youtube video.
Yet I have other videos from the same youtube channel, same settings, and they embed and play perfectly fine inside the content page. I do not understand why this happens or how I am supposed to address it.
