Oh that's unfortunate.

So changing the project name (like FFmpeg does it all the time) does
not constitute changing the copyright notice? Or does FFmpeg violate
the law? Or are you joking?
Some files don't even have a name in the copyright notice. And I bet no

Panning was later reimplemented in libswresample (independently?
unknown), and some time after that, this code was removed and replaced
by using libswresample API.
