            Bug ID: 151294
           Summary: Html5MediaElement missing "crossOrigin" attribute
                    therefore CORS does not work
    Classification: Unclassified

           Version: WebKit Nightly Build
          Hardware: All
                OS: All

Hi I'm not sure if anyone has mentioned this but this standard has been around for a long time now. 

This is not implemented therefore this type of code will not work

this.canvas = document.createElement("canvas");
    this.canvas.setAttribute("width", width);
    this.canvas.setAttribute("height", height);
var ctx = this.canvas.getContext('2d');
 ctx.drawImage(video,0, 0, width, height, x, y, width, height);
var dataURL = this.canvas.toDataURL("image/" + this.type, this.quality);

Both Safari in OSX and IOS, Android default browser and IE11 suffer the same issue. 

It requires a proxy work around setting up a new video for capture or requires Flash to do the capture !   to think it needs a work around like this is silly considering Apple's stance against Flash but then requiring Flash to do captures of video frames. 

It is a fairly common requirement and the deviation from standards is troubling. 

I believe there is a ticket in regards to the 360 webGL CORS which is quickly becoming popular and will be needed. But this is not just drawing to the canvas but "toDataUR" to get the image data uri also. 

Let me know.
