The problematic bit is "mux. ! filesink"

mux. means 'link the left element to a suitable pad on the element named
mux', so the ! after that doesn't make sense.

Try:

gst-launch filesrc location=audio.mp3 ! mp3parse ! mp4mux name=mux
filesink location=output.mp4  filesrc location=image.jpg ! jpegdec !
x264enc ! mux.
