title: Android FFmpeg reports "file protocol not found"
body: <p>I am trying to convert sequence images to video using ffmpeg command in android.
  I have build ffmpeg for android and put ffmpeg binary file in /data/local folder.
  I am running ffmpeg command using <code>Runtime.getruntime.execute("mycommand")</code> in Android.</p>
  
  <p>Stucture of mycommand is like this</p>
  
  <pre><code>"/data/local/ffmpeg -r 40 qscale 2 -i /mnt/sdcard/images/img%d.jpg /mnt/sdcard/images/finalvideo.mp4" 
  </code></pre>
  
  <p><code>mycommand</code> contains the path of a folder where I placed all my sequence images.  Running this command gives me error "protocol not found". </p>
  
  <p>Also I read that file protocol is default in ffmpeg documentation.</p>
  
  <p>How can I run such commands?</p>
  
  <p>The Error I am getting after running simple command like ffmpeg -i /mnt/sdcard/vid.mp4</p>
