title: ffmpeg Error: Pattern type 'glob' was selected but globbing is not support ed by this libavformat build
body: <p>I'm trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"</p>
  
  <p>Example parameters i used:</p>
  
  <pre><code>frame duration  = 2 secs
  frame rate      = 30  fps
  encoder         = libx264 (mpeg)
  input pattern   = "*.jpg"
  output pattern  = video.mp4
  </code></pre>
  
  <p>Based on ffmpeg wiki instructions at (<a href="https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images" rel="noreferrer">https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images</a>), I issued this command:</p>
  
  <pre><code>ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4
  </code></pre>
  
  <p>But I'm getting this error:</p>
  
  <pre><code>[image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not 
  supported by this libavformat build *.jpg: Function not implemented
  </code></pre>
  
  <p>Which probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (<code>ffmpeg-20150702-git-03b2b40-win32-static</code>). </p>
  
  <p>How can I choose a group of files using pattern matching using ffmpeg?</p>
