Use the <video> tag for inserting videos in HTML
The <video> tag is added in HTML5 along with its sibling, <audio>. Before the release of HTML5, a video could only be played in a browser with a plug-in (like a flash). The HTML5 <video> element specifies a standard way to embed a video in a web page. That is to say that the video is identified by adding a video URL to a source attribute. One can use it to embed videos imported from the computer or hosted by an external website.
