if you're stuck on something and can't find an answer, keep trying to rephrase your question. i'd put money down that it is highly unlikely you are the first person attempting whatever you are doing, and it is very likely someone else has had issues like you.
sometimes, searching for the exact error message isn't as useful as one would hope, but with enough time you'll start to recognize how/why those errors are what ffmpeg is struggling with but it is actually something related that you need to address.
wondering if theres a standard set of tooling for creating audio waveform videos?
