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.

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? Last edited by theodirk; 18th May 2015 at 15:52. Reason: show link to other thread |
