title: Android - How to join two videos
body: <p>Basically, I am looking for a way to combine two mp4 video files (on the sd card) together.
  More like, appending the second video at the end of the first one. 
  I have searched a lot, but couldn't find a suitable solution. 
  (well I wasn't able to find any solution at all). </p>
  
  <p>So my question is, Is there a library available that can combine (and possibly trim) videos
  supported by android?</p>
  
  <p>Most of the java libraries I looked for this were platform dependent,
  for ex Xuggler was not much help in this case. </p>
  
  <p>Thanks.</p>
