How to make the Video Autoplay in cms block? Magento 2.2

Question

In Cms Block, I'm trying to add an embed Youtube video that would autoplay upon the page is loaded. However, the part that defines autoplay "?autoplay=1&loop=999999999999&playlist=_bkTXNozzzQ" in the url is trimmed off after saving the block. Is there any way I can make it happen?

Answer 1

If you want to add in cms block try below example:

<iframe width="420" height="315" src="http://www.youtube.com/embed/
oHg5SJYRHA0?autoplay=1" frameborder="0"
allowfullscreen></iframe>

Answer 2

Go to Stores->Configuration->Catalog->Product Video (where you entered the youtube API key). There should be a field called Autostart base video. Set that to Yes after cache clean and check.
