[Solved] HTML5 Video autoplay not working on mobile and chrome browser

I added a video from folder to play automatically on my web page but when i go to my browser to view the page the video does not play automatically in chrome.

And when I navigate to another page where another video is the video will play.

Also when I use mobile device to browse the webpage the video will not have audio. The video does not have audio in mobile device.

Here is how I did it below:

<video controls autoplay loop>
    <source src="video/aboutstc.mp4" type="video/mp4" />
</video>
