not adding src

Someone help.

@technocombo How are you embedding the YouTube video? You should be using an oEmbed instead of adding a raw iframe in your post content. To add an oEmbed, just paste the URL to the video on a paragraph by itself.

Nevertheless if the URL starts with https:// it should not get stripped.

Note also the removal of src being a problem here: https://github.com/Automattic/amp-wp/issues/938

@technocombo Please share the iframe code from your underlying post_content.

Sorry for replying late.

Here’s the iframe code:
<iframe width=”560″ height=”315″ frameborder=”0″ allowfullscreen=”allowfullscreen” src=”https://www.youtube.com/embed/BLgNbncE3E0″></iframe&gt;

Even though the URL starts from https, the amp still strips https from the <amp-iframe>!
Please help

Does oEmbed works on Facebook videos or Bitcoin charts?

Because the problem is same for all. AMP automatically strips out the src from <amp-iframe> tag although using https

I updated the Permalinks. Forgot to say.

In the non-AMP version I’m actually not seeing what you shared. I actually see:

<iframe width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen" src="about:blank" data-rocket-lazyload="fitvidscompatible" data-lazy-src="https://www.youtube.com/embed/BLgNbncE3E0"></iframe><noscript><iframe width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen" src="https://www.youtube.com/embed/BLgNbncE3E0"></iframe></noscript>

It seems this is actually a problem with the plugin “Lazy Load by WP Rocket”: https://github.com/wp-media/rocket-lazy-load/blob/c8af2e40fd346989c3376af6da7c22605ffb1a0e/rocket-lazy-load.php#L447-L527

Try adding the following to your theme’s functions.php to disable the functionality when serving as AMP:

add_filter( 'do_rocket_lazyload_iframes', function( $do_lazyload ) {
    if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) {
        $do_lazyload = false;
    }
    return $do_lazyload;
} );

Thank you so much. That worked really well.

P.S. For those who are getting this error “Uncaught DOMException: Failed to construct ‘PresentationRequest'”, make sure to add the following attribute to your iframe tag:
sandbox=”allow-scripts allow-same-origin allow-presentation”
