I've been trying other people's examples of how to share a webpage with a video on it to facebook, and hoping that the video can play inline in the facebook wall. So far in each of my attempts, facebook only shows the meta information text of my webpage on the profile feed, but doesn't show a video. Here's my HTML code:
<!DOCTYPE html>
<html xmlns:og="http://ogp.me/ns#">
<head>
<title>Ocean Vid</title>
<meta property="og:type" content="video" />
<meta property="og:video:type" content="video/mp4" />
<meta property="og:video:width" content="500" />
<meta property="og:video:height" content="500" />
<meta property="og:video" content="https://mywebapp.com/video/oceans.mp4" />
<meta property="og:video:secure_url"
content="https://mywebapp.com/video/oceans.mp4" />
</head>
<body>
</body>
</html>
What am I doing wrong?
