Gutenberg block and Shortcode for embedding YouTube/Vimeo videos, in a way that prevents users easily accessing the underlying video.
This is useful for example when embedding an “unlisted” video as premium course content behind a paywall on your site.
Features include:
<ul>
<li><a href="https://plyr.io/" rel="nofollow ugc">Plyr</a> player used to overlay default player with custom controls</li>
<li>Player modifications to always prevent clicking the default player</li>
<li>Encodes video ID in HTML to prevent finding it via “View Source”</li>
<li>Settings page to e.g. configure the player theme to match your site</li>
</ul>
<a href="https://protected-video.alecrust.com/" rel="nofollow ugc">View Player Demo</a>
Note: This only provides a basic level of protection. Technical users may still be able to access the underlying video.
This plugin is open source and contributions are welcome <a href="https://github.com/AlecRust/protected-video" rel="nofollow ugc">on GitHub</a>.
