Autoplay in embed video

Hi!

I have a problem with the video on my website. Depends on the fact that when using a video throw by embed code, after the page is loaded runs autoplay.

<iframe type=”audio/mpeg”
src=”https://www.wdecha.pl/wp-content/uploads/2016/06/Sequence-01.mp4&#8243; width=”640″ height=”360″
frameborder=”0″ webkitallowfullscreen
mozallowfullscreen allowfullscreen>
</iframe>
I tried to type autoplay = 0 , etc. However, it does not help.

For this shortcode autoplay does not work , but the mobile version instead view video is displayed white page.

<video src=”https://www.wdecha.pl/wp-content/uploads/2016/06/IMG_1789.mp4&#8243; width=”640″ height=”360″ frameborder=”0″ controls></video>

Do you know perhaps how to deal with this problem? I want to embed a video from my own host , not yt or vimeo.

If you have questions go to the site https://www.wdecha.pl . There are two problematic posts.
I also recommend to enter both on the computer and on your mobile device to see exactly what’s going on.

Thanks for the help
