This our solution ;-)

I got a solution on a page of my index.php in a testing domain, where I just create index.php files and testo my codes, I wrote a solution that the entire embed destroyed by strange symbols, is fixed by symbols written correctly, <> "& Not those strange codes" srsrsrs

  But this has to be applied in the post_content after it creates the post

`
$post = array(
            'post_author'     => '1',
            'post_status'     => $_POST['status'],
            'post_type'       => $cpt,
            'post_title'      => (string) $feed_item->title,
            'post_content'    => (string) $feed_item->desc
            );
        $post_id = wp_insert_post( $post );
        update_post_meta($post_id, 'sponsor',      (string)$_POST['source']);
        update_post_meta($post_id, 'videoID',      (string)$feed_item->id);

// hercules arrays:
        $myembeddirty = array('ID:','&lt;','&quot;','&amp;','&gt;'
);
        $myembedcleaner = array('','<','"','&','>'
);
/*
From now on, clearly I do not know what I'm doing srsr
I do not know how to call by post_content above, would it be with $ post_content?
I suffer with this case, because cron has a minimum of one hour, and I already used grep
From linux to see if I can find the code to slow this time I can not!
So every new try I have to wait an hour to see if it works!
*/
      $post = get_post( $post_ID );
      $post->post_content;
/*
THE SOLUTION:
      //$mynewdesc = $post->post_content;
     //$mynewdesc = str_replace($myembeddirty, $myembedcleaner,  $mynewdesc);  //this solve the PROBLEM do embed breaked from htmlentities, but I don't know apply in $post_content
*/
        $post->post_content = str_replace($myembeddirty, $myembedcleaner,  $post->post_content);
        $post = array(
          'post_content' =>   $post->post_content,
         );
          wp_insert_post($post_id);
