title: How can I view the "code" of a .mp4 video file?
body: <p>I know that my terminology is not correct, but I am a complete novice when it comes to video. </p>
  
  <p>I have a regular .mp4 video file. I use MP4Box to segment the video file so I can play it back using a video player that supports MPEG dash. It is not segmented by creating multiple smaller video files. It creates a new, large video file that is a bit larger than the old video file.</p>
  
  <p>I want to compare the regular video file with the dashed video file and see what MP4Box does to it to segment it. I believe that it is adding some type of header to the new video file. Obviously when I open it up in a text editor, it is unreadable. How can I go about comparing these files?</p>
