Is it possible to display video from post?

I’m interested to know this as well, I can’t get it to work even with the custom filter in functions.php

If you want to show just screenshot and link to post then you can do that with CSS. You can use some other plugin to add auto featured image for youtube videos.

<div class="recent_videos">[display-posts category="videos" wrapper="div" posts_per_page="5" image_size="medium" order="DESC" orderby="date"]</div>

Then add css in .recent_videos {} and .recent_videos img {} to align title and image, also set width and height for image.
