a ?? dat file ??
*.DAT are normally windows raw file for say a game


so what exactly is this "dat" file ?
mplayer thinks it is a mpeg compressed file ?
or is it some raw camera file

what produced this "dat" file

is it supposed to be a music audio file or a video file ?

sumeet inani 01-09-2014 09:39 AM
It is video file from a bought CD .
I will post its ffmpeg analysis ASAP.

John VV 01-09-2014 01:03 PM
so it is from a 700 meg video CD

i am betting someone used some DRM encryption schema on it to keep people from copying it

a guess here ....
it is a game cd and you are trying to pull parts of the video out of it
if so that "dat" file is likely in a proprietary format and you need to contact the game publisher

if you read the file using a hex editor you can read the text in the video header
ghex or ockular

sumeet inani 01-13-2014 05:44 AM
It is movie CD .
If it is DRM encrypted then the question arises - how does it get played by mplayer from command line but NOT from same binary when double clicked ?
Anyway here is its ffmpeg analysis
