Can't you just show us the output of
ffmpeg -i videofile
or
ffprobe videofile
??

Answering your question without knowing your file:
Use "-map" to select the video stream to extract.
(There's probably a command to do all four extractions & remuxings in
one command. I leave that to the other list readers.)
