There are five ways to deal with the protections against cross-origin retrieval:

1. CORS headers -- this is ideal, but you need the cooperation of the third-party server
2. JSONP -- not appropriate for streaming content and you typically need the cooperation of the third-party server
3. Iframes and inter-window communication -- probably not appropriate for streaming content and you need the cooperation of the third-party server
4. Turning off browser protections -- you need to be running the browser in a custom mode, and you should not use that browser for anything else
5. Server-side proxy -- comparatively slow but often the only feasible option
