Error with getID3 with SermonSpeaker 7

I just tried to set up a similar article like you have, and for me it works works as expected.

Maybe you had some browser cache issues after updating the site? Make sure to clear the browser (by force reload with Ctrl-F5 or clearing cache in the settings) and Joomla cache after the update to be sure.

From your list, I see you still have a language pack installed. You can uninstall that one. The current files are included with the extensions for quite some years and your language pack would overwrite it with 10 year old strings.

Thank you again. 
From my situation with Joomla 6 and SermonSpeaker 6 (fully functional) I have upgraded all components, modules and plugins to Sermonspreaker 7, one by one and now most things work OK. I do have the livestream iFrame on teh homepage working correctly. But when I test the video sermon archive, which is basically a sermonlist I still have a problem with the player frame. It opens bigger, but immediately shrinks to a size that the start button is almost covering the whole frame. If I look at the 'preview' in the sermon editor it looks perfect, but when I open the same sermon from the sermon archive list I see the shrinked player. 

See screenshots:
 
    

Hmm, that looks like an issue with a specific sermon detailpage layout.
Which one did you use here? And can you try to change it to eg "content"?
You can set the layout SermonSpeaker uses in the SermonSpeaker Options, in the Layouts tab. Or it can be overwritten in the active menuitem, so maybe check that as well.

Thanks again Thomas!
Indeed that did the trick: I have switched the "single sermon' to "content" in the menuitem layout tab. And I have changed the default in the Global settings. 

It remains strange that it worked OK with SermonSpeaker in both Joomla 5.4 and Joomla 6.0, but I am happy it is working correctly now.
