That error message is pretty clear. You are trying to use "-c:v copy"
while applying a filter. That can never work.

Actually, you are providing the codec twice: "-vcodec libx264" and "-c:v
copy". Probably, the latter is just a copy/paste error.

I am convinced you will run into other issues with your command line.
E.g. I believe you are not mapping your inputs correctly, and I think
YouTube requires a stereo audio stream. But I'm just guessing. Please
be sure to always provide the complete, uncut console output (minus
your YouTube key) of your ffmpeg command when asking for assistence
here.

BTW, there's usually nothing (at all!) which justifies running such a
command with root priviledges.
