YouTube iframe embeds often load many unnecessary resources, which slows down your page. YEP: Optimize YouTube Embeds is a lightweight WordPress plugin that replaces YouTube iframes with a clickable preview image. 
The actual video loads only when the user clicks the play button, improving page load times and reducing initial page size.
<h3>External services</h3>
This plugin uses the external YouTube thumbnail service (https://i.ytimg.com) to display preview images of YouTube videos. 
When a page with a YouTube embed is loaded, the plugin requests the thumbnail image directly from YouTube servers. 
No personal data is sent from your site to YouTube, only the video ID (already public in the YouTube URL).

<li>autohide (supported players: AS3, HTML5)
<ul>
<li>
Values: 2 (default), 1, and 0. This parameter indicates whether the video controls will automatically hide after a video begins playing. The default behavior (autohide=2) is for the video progress bar to fade out while the player controls (play button, volume control, etc.) remain visible.
If this parameter is set to 1, then the video progress bar and the player controls will slide out of view a couple of seconds after the video starts playing. They will only reappear if the user moves her mouse over the video player or presses a key on her keyboard. 
 If this parameter is set to 0, the video progress bar and the video player controls will be visible throughout the video and in fullscreen.

</li>
</ul>
</li>
<li>controls (supported players: AS3, HTML5)
<ul>
<li>
Values: 0, 1, or 2. Default is 1. This parameter indicates whether the video player controls will display. For IFrame embeds that load a Flash player, it also defines when the controls display in the player as well as when the player will load:
<ul>
<li>controls=0 – Player controls do not display in the player. For IFrame embeds, the Flash player loads immediately.</li>
<li>controls=1 – Player controls display in the player. For IFrame embeds, the controls display immediately and the Flash player also loads immediately.</li>
