Presently there is now way for us to 'embed' videos from commons in our blog posts. We don't simply want to reference the video files since it can include community translated subtitles. To address this mwEmbed includes a "share button":
But the <object> tag it produces is striped by wordpress on saving the blog post.
It would be fairly trival to either
a) add a handler to our config:
b) Create a wordpress 'commons embed' plug-in
If this is something we want to do, and will be installed once I create it, I will make it happen.
