title: How to read mp4 video to be processed by scikit-image?
body: <p>I would like to apply a <code>scikit-image</code> function (specifically the template matching function <code>match_template</code>) to the frames of a <code>mp4</code> video, <code>h264</code> encoding. It's important for my application to track the time of each frame, but I know the framerate so I can easily calculate from the frame number.</p>
  
  <p>Please note that I'm running on low resources, and I would like to keep dependencies as slim as possible: <code>numpy</code> is needed anyway, and since I'm planning to use <code>scikit-image</code>, I would avoid importing (and compiling) <code>openCV</code> just to read the video.</p>
  
  <p>I see at the bottom of <a href="http://scikit-image.org/docs/stable/user_guide/numpy_images.html">this</a> page that <code>scikit-image</code> can seamleassly process video stored as a <code>numpy</code> array, obtaining that would thus be ideal.</p>
