I guess you're getting downvoted since the claim that "FFmpeg is now somewhat broken" remains unsubstantiated. You're relying on information from LLMs which by definition are closer to random guesses than anything else. Effectively, what you're saying is that you cannot be bothered to learn the actual, albeit complex, syntax of FFmpeg to solve your problem, which is totally fine and up to you, but your conclusion that the tool is broken is like saying "this car is broken" when you don't know how to operate it and drive.
