当我使用以下OG元数据将视频嵌入facebook时，我看到facebook正在图像上嵌入标题和域，如何避免？

当我使用以下元数据将视频嵌入facebook时，我能够成功地嵌入视频，但我不希望facebook在嵌入后将文本添加到图像顶部。我怎么做

<meta property="og:type" content="movie"/>
<meta property="og:video:type" content="application/x-shockwave-flash" />
<meta property="og:video" content="http://player.theplatform.com/p/yHjoOC/onsite_dev/swf/select/nEdMK4_islkz&autoPlay=true" />
<meta property="og:video:height" content="265" /> 
<meta property="og:video:width" content="470" /> 
<meta property="og:video:secure_url" content="https://player.theplatform.com/p/yHjoOC/onsite_dev/swf/select/nEdMK4_islkz&autoPlay=true" />
<meta property="og:title" content="Christina Aguilera On The Voice"/>
<meta property="og:description" content="Christina Aguilera gives insight on her team and competition." />
<meta property="og:image" content="https://mpxstatic-nbcmpx.nbcuni.com/NBCdotCOM/mezzthumb/9d883881039c20870dfeaf068a5be0e7_1c966ee53db728d715881e1cf193ebc2.jpg"/>

请帮助我如何实现这一点。

它的facebook默认行为，因此我们无法更改它
