  74 autovideosrc is a video src that automatically detects an appropriate
  75 video source to use.  It does so by scanning the registry for all elements
  76 that have <span class="quote">“<span class="quote">Source</span>”</span> and <span class="quote">“<span class="quote">Video</span>”</span> in the class field
  77 of their element information, and also have a non-zero autoplugging rank.
