Comment (by ami_stuff):

 In this case the file is flipped unnecessary.

 libavcodec/mjpegdec.c:
 {{{
             else if((len > 20 && !strncmp(cbuf, "Intel(R) JPEG Library",
 21)) ||
                     (len > 19 && !strncmp(cbuf, "Metasoft MJPEG Codec",
 20))){
 -                s->flipped = 1;
 +                s->flipped = 0;
             }
 }}}

 so it looks like the intel jpeg encoder can save flipped and not flipped
 jpeg frames and the question is how to identify which frames should be
 fliped and which not.
