How can developers ensure cross-browser compatibility for HTML5 video elements without relying on external libraries like jQuery?

To ensure cross-browser compatibility for HTML5 video elements without relying on external libraries like jQuery, developers can use feature detection to check if the browser supports certain video formats and fallback options. This can be achieved by using the <video> element with multiple <source> elements for different video formats and a <p> element for a text fallback option. 

&lt;video controls&gt;
  &lt;source src=&quot;movie.mp4&quot; type=&quot;video/mp4&quot;&gt;
  &lt;source src=&quot;movie.ogg&quot; type=&quot;video/ogg&quot;&gt;
  &lt;p&gt;Your browser does not support the video tag.&lt;/p&gt;
&lt;/video&gt;
