When embedding a video into a blog post you may want to have it start auto playing, i.e. without the website visitor having to click the play button when they visit the page.
To have a video auto play follow these steps.
1. Insert the YouTube HTML code as you normally would into the blog post.
2. Insert the following text at the end of the YouTube link which is contained in the HTML code you have pasted into the blog post ?autoplay=1
For example the YouTube standard embed code would look like this:
<iframe width="560" height="315" src="https://www.youtube.com/embed/thhvqSwz9c0" frameborder="0" allowfullscreen></iframe>
After inserting ?autoplay=1 it would look like this (highlighted area is just to show where the difference is):
<iframe width="560" height="315" src="https://www.youtube.com/embed/thhvqSwz9c0?autoplay=1" frameborder="0" allowfullscreen="">
</iframe>
3. Save the blog post.
4. Visit the blog post page to test that the auto play scripting has worked.
Process Complete.
