custom file recovery

[inou81]

I have a security camera DVR that i need to recover some video from. The file extension is .264 I have tried to use the GUI based tool to add the file type as well as follow the instructions posted on this forum. I cant seem to figure out what I am doing wrong. Any help would be appreciated.

I downloaded one file, then that file hosting ask me to wait app. half an hour to download another one. So, maybe next day I'll be able to look at those files.

Try this one:
<?xml version="1.0" encoding="UTF-8"?>
<FileTypeList version="2.0">
<FileType id="50001" group="DVR Video" description="DVR files" features="" extension="264">
<Begin combine="OR">
<Signature offset="80">MDVR96NT\x5f2\x5fR</Signature>
</Begin>
<End combine="OR"/>
</FileType>
</FileTypeList>
Unfortunately, I couldn't find a signature for the file end. So, it would be not easy to find file ends.
