title: How to add different Quality in a Single video in my website?
body: <p>How can I add different Quality in videos. Do I have to embed it in  or  or any other tag . I mean I want to open a video website. Now I have to post 720p and 1080p. I have to post them separately. But I want them to be posted at once in same video . The people could change the Quality just by choosing like YouTube. Or Is there anyway I can post 2 separate button. 1. 720p 2. 1080p . By Clicking no. 1 a video will be open in the same page. Then clicking no.2 the other Quality video will open in same place as 720p video and forcing the 720p to be hidden</p>
