Have you tried to remux the MP4 file? Or have you tried to use *vlc* --*
demux=avformat http://www.ltuic.latrobe.edu.au/rob_vid1.mp4*

> We're using the Mozilla firefox plug-in to provide an interface to a custom

> media files accessed via HTTP using any VLC older than 0.9.9 (in both QT GUI
> and Mozilla plug-in). I posted this information to the VLC forums[0], and it
> was suggested that I try here.

> The test mp4 file we've used is available at

> vlc-1.1.0-pre3-20100502-1255-win32, 1.2.0-git-20100508-0002-win32. The
