macOS Catalina MonoWriter: Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead

Hello, if I see this error should I downgrade ffmpeg? Or is it user error? waf run_tests looks good. Sorry for the newb question this is my first time using essential. Read on for more details...

When I compile, install, link and run essential within an Xcode project on macOS Catalina I see the runtime error:

"Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead"
