title: FFMpeg convert VOB to H264 and multi language
body: <p>I try to convert VOB files to H264. I know it seems to be crazy to do that but the goal is to use it with the Apple TV.</p>
  
  <p>To just converting a VOB file to mp4 with the right audio stream is not really a problem. </p>
  
  <p>The problem is when the VOB file contains multi-sequences in different languages. For example, in the mp4's file I will have 3 seconds of video including for example a book on the screen in english, then, the same 3 seconds with the book in french and so on...
  But with the VOB file I will have only the 3 seconds in the right language.</p>
  
  <p>When I check the VOB file, I only see one stream #0.0 for the video.</p>
  
  <p>So my question is, how can I avoid to include the differents videos sequences with these different languages ?</p>
  
  <p>Thx for your help. </p>
