You tube default width

Great plug-in. Have a small question. How can i change the default width of embedded YouTube videos? (by editing the css file)

    @PRAB AFAIK, you can't change the embeded videos through CSS. However, in mediator.js, the lines 44-49 set the width up conditionally.

    function Mediator () {
      var mlist = $('.MessageList .Message');
      if (mlist.width() < 640) {
        width = mlist.width() - 40;
        height = width * 0.5625;
      } else {
        width = 640;
        height = 360;

    You change this to:

    function Mediator () {
      //var mlist = $('.MessageList .Message');
      //if (mlist.width() < 640) {
      //  width = mlist.width() - 40;
      //  height = width * 0.5625;
      //} else {
      //  width = 640;
      //  height = 360;
      width = 1280;
      height = 720;

    changing the last numbers to whatever you want.

    Thanks a lot @hgtonight!

    @PRAB, the above solution should work indeed. Do let me know if it doesn't, and I'll figure out a fix.

    You can use css to control the embedded content , if the embedded content is an iframe you would just add iframe to the list below. I use this all the time to keep everything the size I want regardless of what they embed and how big. This would go in your custom.css file of your theme.

    .Preview .Message, .MessageList .Message .Video object embed {
    width: 680px;
    height: 420px;

    here is screens of it.I made the embed object here very wide so it reaches to the other side under the panel. in the first image the second I made the embed object the width of the content only with css and overriding any size the embed may contain.
