Thanks for clearing this up!

I actually mistook it for some kind of warning, so I'm wondering: How 
could someone who sees such a message know if it's a warning or just 
informal?

When I teach FFmpeg handling to e.g. archivists, I usually tell them to 
watch out for anything that "looks unclean" in the process. The message 
contains the word "invalid" - which is why this ended up on my table for 
inspection :)



Grateful for any suggestions, but also fine if "that's just how it is" ;)
