WebGL video playing in safari.

I tried to play video in unity webGL. By default, unity doesn't provide support for this. So, I tried to use the plugin Simple movie texture https://www.assetstore.unity3d.com/en/#!/content/38369 . But this plugin doesn't seem to work in safari. It's working fine in chrome and firefox.But , In safari, i am getting the following error. " INVALID_VALUE: texImage2D: no video". Can anyone help me out of this
