Comment field like Buzzfeed

I need a comment field like buzzfeed.com has with the possibility for the user to easily add a picture (either link or upload), video or link to any post. Does any wordpress plugin exist for this?

Also if a video link (for example to youtube) is provided, the video should be displayed inline in the comment. I saw that wordpress.com supports this, but wasn’t able to find a corresponding plugin, which doesn’t require the user to enter some markup code or change the url
