Comment (by stha02):

 The error means that the control V4L2_CID_EXPOSURE_AUTO could not be read
 and will not be used (just means that you will not be able to use
 automatic exposure control) and "extraneous bytes before marker" is just
 an annoying warning which could be ignored.

 I am not sure whether I understand your last question. If the camera
 supports jpeg-compression (image/jpeg), you should use
 camera.camera_format = :MODE_JPEG (camera will do the work for you)
 camera.output_format = :MODE_UNDEFINED (just keep the received format)
