title: Create slideshow from images on linux
body: <p>I need to dynamically create a simple but nice slideshow from images on my linux server (CentOs). I'm using <code>php</code> with the <code>dvd-slideshow</code> and <code>ffmpeg</code> tools, but dvd-slideshow is very limited: </p>
  
  <p>1) The quality is absolutely too poor: there's definitely too much loss of quality from the <code>pngs</code> to the final <code>vob</code> file and no parameter seem to help in this.</p>
  
  <p>2) I can't apply the (just 4) effects on just some part of the frame running at the moment.</p>
  
  <p>Example using: <code>dvd-slideshow -n test_video -H -sharpen -w template1.txt</code> </p>
  
  <p>I can't find any tool better than this to use to create my slideshow in the whole www. Can you suggest any? I can use whichever alternative can be flow-controlled by <code>php</code>: </p>
  
  <p>1) Every command line tool in linux.</p>
  
  <p>2) Libraries/scripts in <code>python</code> or <code>ruby</code> (but nothing that need Spielberg to be used with).</p>
  
  <p>3) New <code>canvas</code> or <code>js</code> library running on nodejs technologies.</p>
  
  <p>4) No online service like <code>flickfusion</code>...</p>
  
  <p>Can anyone point me to any solution?</p>
