AMP error in search console

Hello, guys.
In the last couple of months, we’d have been experiencing some issues in the Google Search Console. In this one, for example, it throws us: The tag ‘img’ should be replaced with an equivalent ‘amp-img’ tag..
We reviewed this, and we found that the Embed Plus for YouTube plugin is using a png image to show the play button on the gallery videos, but it’s not showing the correct structure for AMP pages.
How can we address this issue?

Thanks in advance for your reply.
