title: What is the file format of .dav file / How to read a .dav file in java
body: <p>I have a .dav file from a security camera (CP Plus).</p>
  
  <p>DAV files are created by a DVR365 digital video recorder, and are used for recording video captured by CCTV cameras. These files incorporate modified MPEG compression and are saved in an encrypted format. <a href="http://www.openthefile.net/extension/dav" rel="nofollow">More Info</a></p>
  
  <p>I need to reverse engineer a .dav file so as to enable me to read the same. 
  Does anybody know the structure of a .dav file ?
  Further, is there any tool in linux which can convert a .dav file to a standard format like mp4/avi/mov/flv ... etc.</p>
