Bug 103257 – crossOrigin property on HTMLMediaElement is not supported

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Media

[Antoine Quint]

It appears the crossOrigin property of HTMLMediaElement is not support at all. This makes the Opera-submitted test at http://w3c-test.org/html/tests/submission/Opera/media/interfaces/HTMLElement/HTMLMediaElement/crossOrigin.html fail.

Let me bring example code over to here with one exception. IOS didn't like the extra arguments to drawImage and produces a blank canvas ! 

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);
var dataURL = this.canvas.toDataURL("image/" + this.type, this.quality);

Without the proxy work around this will fail because lack of crossorigin attribute. The default android browser suffers the same issue however it also fails with the security work around ! 

Here is a working example for safari IOS and IE11 with the proxy work around, it makes a capture from an offscreen video tag with the reformatted url of the same sub domain, it will fail even with the same top level domain.

An example of the nginx proxy in action,

flowplayer.electroteque.org/video/big_buck_bunny_480p_h264.mp4

it does an nginx reverse proxy to 

videos.electroteque.org/big_buck_bunny_480p_h264.mp4

I think it is now supported because I can see "crossOrigin" in HTMLMediaElement source file on Webkit Github mirror.

If someone else need to be done, please update or open separate bugs. Also I am unable to retrieve above Opera submitted result. I tried to look into WPT.FYI but didn't find this test as well (might have been renamed). Thanks!
