<h4>General Information and Features</h4>
<p>The Falconiform YouTube Widget allows you to add YouTube videos to your sidebars. This is easily done by adding the widget to a sidebar in the administration interface. After that you simply paste the link (URL) of the desired YouTube video (or the video ID) into the appropriate widget settings field. You can adjust the following settings:</p>
<ul>
<li>widget title</li>
<li>YouTube video ID</li>
<li>player width (automatic width possible)</li>
<li>player height (automatic height possible)</li>
<li>player theme</li>
<li>color of the player’s video progress bar</li>
<li>player controls visibility</li>
<li>hide controls / progress bar at playback</li>
<li>start playback automatically</li>
<li>restart the video automatically after playback ends (loop video)</li>
<li>show related videos after playback ends</li>
<li>show video information like the video title</li>
<li>show video annotations</li>
<li>show fullscreen button</li>
<li>hide YouTube logo in the controls bar</li>
<li>disable keyboard control for the player</li>
</ul>
<h4>Editors Can Specify Videos</h4>
<p>Optionally, the Falconiform YouTube Widget allows users with Editor rights to specify the video that is shown in the sidebar. In WordPress Editors are not allowed to change widget settings. Therefore the Falconiform YouTube Widget adds an extra menu to the administration interface that allows Editors to specify videos that are linked with one or more YouTube widgets (via index number).</p>
<p>If you don’t want Editors to specify videos, you can disable this in the widget settings (disabled by default).</p>
<h4>Technical Details</h4>

Details about the YouTube player can be found at <a href="https://developers.google.com/youtube/player_parameters" rel="nofollow ugc">YouTube Embedded Players and Player Parameters</a>. The HTML output of this plugin was checked against HTML5 conformance successfully.</p>

You can add a line to your functions.php to make videos responsive if you're doing your own theme. However, if you're not, this plugin works beautifully and gives other options like lazy load, etc. 

If doing your own theme, add: add_theme_support( 'responsive-embeds' );
