The h264dump.h264 does not look to be correct: Does it include the IDR frames ( like SPS, PPS, video header information).
You can attach the video here, so users here may help to have check.
I just checked your file with other tools( FFMPEG etc). It fails as well. The simpleplayer can take the raw H.264 stream (bit stream format).
I am not sure about the output of rtpdump in wireshark. I just did a quick search, it looks it produce a different output here: http://www.cs.columbia.edu/irt/software/rtptools/#rtpdump
