Maybe what Jimmy is saying is you don't need -pix_fmt h264 as you
already have -input_format h264. If removing it gives the same logging
output then it's not needed.

As has been said, you are getting compressed h264 from the camera, but
you are using -r 20 which means you are requesting 20 fps not 30. You
should also probably use -framerate 30 rather than -r 30 - there may
be a difference in behavior.

The fact you see yuvj420p is not an error, it is reporting what the
h264 stream was before it was encoded.
