title: Cannot play any file with JMStudio after installing fobs4jmf or jffmpeg
body: <p>I'm currently developing a multimedia application in Java using Eclipse IDE and JMF API on Windows7. However, I can only play <code>.midi</code> and <code>.mp3</code> files in my app. This is a bit normal because JMF supports a very limited number of formats and the mp3 plugin must be built in. Strangely enough, JMStudio can't play any file, be it an mp3 or a midi file. </p>
  
  <p>I extended the API by <a href="http://fobs.sourceforge.net/f4jmf_first.html" rel="nofollow">following the instructions provided</a>, and registering the fobs4jmf plugin with JMStudio as indicated. I also added the necessary jars in the classpath and moved <code>fobs4jmf.dll</code> to <code>Windows/System32</code>, but the result is still the same -  JMStudio can't play any file I open, nothing happens. </p>
  
  <p>More importantly, JMStudio complains that it can't create a Player for a file I did not even choose on subsequent attempts to open a file. Here's what the errors says the second time I open a file:</p>
  
  <blockquote>
    <p>JMStudio Error</p>
    
    <p>Could not create player for file:</p>
    
    <p>nullnullnullnullnullnullnullC:\myFile\MUSIC......\Tu M'en Veux(chui,
    chui,chui).mp3</p>
  </blockquote>
  
  <p>The error is exactly the same for any file I open upon failure of the first.
  I get the same result if I separately register the jffmpeg plugin (which is actually a jar) with JMStudio.</p>
