Question about NVMS and MP4 (DVR video files)

I have a file that was taken from a customer DVR they installed and it claims to be a .MP4 file, yet will not work with any player that I have tested. However, the file does play in the included "MP4" player from Zmodo.

I have uploaded an example "MP4" and the Zmodo player software (210 MB) to:

http://www.megafileupload.com/12u4/MP4_Player.zip

http://www.filedropper.com/mp4player


Link to Zmodo Page with software under SAN4, SAN8, SBN4,SBN8, SBN6: http://kb.zmodo.com/index.php?action...=29&artlang=en



Could anyone help me figure out why it doesn't play in VLC or other real player and how to convert it to a real MP4? These types of files are common throughout the cheap chinese dvrs available on the market. It would be nice to have a way to view these files without having to download the individual "player" from each vendor.

Thank you.

Whatever it is, it's not an mp4. It has "MPG4" in the header, though, which led me to this blog post that exactly describes the file... unfortunately, a dead end for conversion. Eyeballing the hex view, it looks like a very thin wrapper around raw h.264, but you'd want a tool to extract that and I don't know of one.

dump the h264 stream out from RAM directly when you are playing the file with whatever the heck player, maybe?

If, then

So, if it can be done as a raw h.264, how can I convert that into a real MP4?

Would the methods in this thread: http://forum.doom9.org/showthread.php?t=129096 work?
