<p>autovideosrc is a video src that automatically detects an appropriate
video source to use. It does so by scanning the registry for all elements
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
of their element information, and also have a non-zero autoplugging rank.</p>
