Access-Control-Allow-Origin HTTP Header needed
When streaming video (or audio) from VLC using HTTP protocol, there should be way to enable 'Access-Control-Allow-Origin' header in VLC response. This header is needed to tell web browser it's allowed to get raw access to data streamed from VLC even when it's loaded from different server.
Without this header, it's not possible to do any pixel manipulation for video stream unless video stream is coming from same server as HTML page.
