MP4 with mono track garbled in Linux

Playing videos with media control in Java FX under Linux Mint 15,16,17
and upstream Ubuntu is garbled. MP4 files are produced with Flip camera
and have the following signature below. Key difference with MP4
videos that do play is the mono track. Other players (VLC, MPLayer, Xine)
all work fine.
