php - Xpath get video tag fallback image

one text

I'm working on some Xpath for website scraping, but need to get the image from a video tag.

I'm working in PHP and using Atrox\Matcher for the retrieving of data.

I currently have this code:

//div[@class="drop-body"]/video/*/@src

But this only gets the video src. Is there a way to get the fallback image with xPath?

This is the code I'm trying to scrape:

<video autoplay="" muted="" playsinline="" loop="">
   <source src="*" type="video/webm">
   <source src="*" type="video/mp4">
   <img src="*" title="Your browser does not support the <video> tag">
</video>
