Error with getID3 with SermonSpeaker 7

I have upgraded our Church website to Joomla 6 and installed SermonSpeaker 7. After installing the separate components that seems to work now. 
Only, if I make a new sermon or try to save after making an edit, I get the error message (although the updated sermon is saved correctly): An error has occurred.

0 Class "getID3" not found

We are working with PHP 8.4 
Any idea's what that can be?
 

Ups, looks like I forgot to include the autoloader for those classes.
Can you try the attached version? If that works for you, I can release a new version with that fix.
 

Yes, that works!
Thank you very much for the quick fix

Sorry I was too quick
Indeed I could save new or updated sermons without an error, but now the video sermons don't show in a proper iframe anymore (see screenshot of what it should be)

I have restored a backup from directly after the upgrade from Jommla 5.4.1. to 6.0.1. with still Sermonspreaker 6.x in it. And that combination works correctly! 
It looks like I can better not upgrade to ss verseion 7 yet

That would more be an issue with the player plugin than with the component itself. Which version of which player plugin are you using (MediaElement.js 7.0.1 would be recommended)?

Also, it looks like you're using the content plugin to load two players into an article or custom module? Is that right? Then I can try to reproduce it.

I had indeed MediaElement.js 7.0.1  installed and we are using the Content plugin. 
b.t.w. I am testing Joomla 6 in our development environment - development.bereadematen.nl and as said I rolled that back to SermonSpeaker 6, so I can do any sequence of installs and test wiyhout damage. 

For your info I will include what is installed at this moment
