What you are creating implies the "image2" muxer. Check its documentation:
So this should do the right thing for you:
ffmpeg -i "Foobar.mp4" -f image2 -start_number 0 "Frame%05d.png"
And in this case, you can continue to omit the implicit muxer:
ffmpeg -i "Foobar.mp4" -start_number 0 "Frame%05d.png"
P.S.: Despite being a programmer, it often riddles me why anyone would
like to start counting with 0. ;-)
