Yes. What are you implying with your question? That the behavior is
neither a bug nor is it the way ffplay was intended to behave? (Do you
not understand "or", or do you not understand "intended"?)

*I* was trying to say: If Mohammed's expectation was correct - I did
follow it for a while - then it's some sort of bug. OTOH, if this
behavior was intended, then it's obviously correct. Perhaps I should
have written: "I'm not sure this is the intended behavior." (I am now.)

(By the way, I was truly misled by the fact that I found no audio
"equivalent" of "-nodisp", and thought it implied "don't play, just
decode", when in fact it's an alias for "-vn" and the equivalent is
"-an".)

Then does it not also "work" as expected?

I find ffplay's error message misleading, but "patch surely welcome,
but no patch attached".
