Broken MP4 --Need Your Help

[sony1118]

Hi All the expert members out here,

I am pretty new here. However before posting this I have tried to do my due diligence on searching the forum forum for the solution for my problem. However I could not find one.

Here is the Problem which I am having, I have a movie mp4 file which a friend of mine gave it to me and and it is about 1.5GB. I dont know the source of it, however the file seems to be completely unplayable. I tried all different players (Quicktime, VLC, windows media player etc). Also I tried to open the file in other software to change it to avi or another format, using Loiloscope but could not open it.

So I start more poking around and see if I can find some solution -- There was a solution about Grub Video Repair tool, I tried that as well, it did not work. Then I checked whether the file can be repaired or not going on mp4repair.org. Found that file can be repaired.

So then I started to see where the file could be wrong, there were some suggestions to check Atomic Parsley -- See the image

Also Here is the Media Info of the file (see image)

Also here is the portion of the Hex editor output for the file (See below) and also the image

Based on what I can interpret from my limited knowledge base that somewhere in the MP4 file the headers are corrputed, because when I looked the media info and atomic parsley of known good files i could get expected output.

Anykind of help is greatly appreciated..

Regards..

You can try untrunc (in a Linux emulator) and recover_mp4_to_h264. In both cases you will need to supply a healthy MP4 file with what you believe to be a matching structure.

Have you tried FFMPEG or WinFF?
