HTML Video
The HTML <video> Element
To show a video in HTML, use the <video> element:
How it Works
The controls attribute adds video controls, like play, pause, and volume.
It is a good idea to always include width and height attributes. If height and width are not set, the page might flicker while the video loads.
The <source> element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format.
The text between the <video> and </video> tags will only be displayed in browsers that do not support the <video> element.
HTML <video> Autoplay
To start a video automatically, use the autoplay attribute:
Add muted after autoplay to let your video start playing automatically (but muted):
Note: Chromium browsers do not allow autoplay in most cases. However, muted autoplay is always allowed.

The numbers in the table specify the first browser version that fully supports the<video> element.
