我有一个简单的共享按钮,可以将某些视频分享到facebook,不幸的是,只有图像显示,但是这里没有视频
<meta property="og:url" content="https://meed.audiencevideo.com" />
<meta property="og:video:type" content="video/mp4"/>
<meta property="og:title" content="test title" />
<meta property="og:description" content="Test" />
<meta property="og:image" content="https://meed.audiencevideo.com/images/thumbnail.PNG" />
<meta property="og:video:secure_url" content="https://meed.audiencevideo.com/videos/good_job.mp4" />
<meta property="og:video" content="https://meed.audiencevideo.com/videos/good_job.mp4" />
<meta property="og:video:width" content="398">
<meta property="og:video:height" content="264">
我的代码中缺少什么?
