title: How To create mosaic with live stream with ffmpeg ( or with xuggle )
body: <p>For a thousand minutes I try to find a way that stream multiple video and combine them into a one output . I wanna do that with ffmpeg or xuggler with ffmpeg cmd.
  VirtualDub and avis couldn't meet my needs. Actually I couldn't find a way stream in avis . I can only make 4 8 16 videos in a screen on virtualdub but they are local videos and not my issue .</p>
  
  <pre><code>&gt;cd c:\f\bin 
  </code></pre>
  
  <blockquote>
    <p>ffmpeg -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=other stream, scale=iw/4:ih/4 [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k output</p>
  </blockquote>
  
  <p>anyway join two stream side by side , but I want more . 
  Is it possible with ffmpeg ? Also 
  I cant use the program like spycam ,vlc etc . Don't say to me vlc , console vlc can easily do it .  </p>
