I&#x27;m not sure if this is what you&#x27;re referring to, but they also don&#x27;t allow you to embed a custom HTML5 player, just Flash. So, if you&#x27;re a content producer or platform that wants to use your own player, your only option is to embed a SWF.<p>The irony is that I&#x27;m pretty sure the reasoning has security in there somewhere.
