video file won't play. need to know what type it is - what codec?

[chriscaton]

Hi. I just pulled a video clip off off a DVR used for closed circuit cameras. I just have one camera in test mode and pulled a 3-4 minute clip to USB.

I took it to my computer and none of my video programs will play it. I need to find out if it's just a codec i'm missing or is there something wrong with the file itself.

would anyone be willing to take a look at the file? it's about 2.3M. i can email it as necessary..

thanks

Chris

If the extension is hidden start - > control panel -> folder options ->view ->uncheck " hide extension for known file types then click ok. See if the extension becomes visible.

the ext is .mpg (extensions and file types are not hidden)

the is a new unit that i have setup to test. The last thing i have to do is extract and play video...

what other player other than WMP, VLC, QT, moviemaker would anyone suggest trying. anyway to analyze the file?

I have seen raw mpeg files that would not play in windows, can you inport it into virtualdubmod?

[chriscaton]

i just tried to open using virtualdub, virtualdobmod, and avidemux. All gave invalid file type.... I'll try to contact the manufacturer tomorrow unless there are any other suggestions.

Thanks for the help

You can also try loading it into GSpot or MediaInfo and posting a screenshot (in GSpot's case) or cut and paste the information from MediaInfo's Tree View, here, and maybe someone will be able to know what to do with it. Blank out the path and/or filename if you prefer.

Most security camera DVRs use proprietary codecs. Google the model number to see if anyone has cracked that model.

Why not post the video file somewhere like megaupload so we can look at it.
