Cross origin problems with video

`Failed to execute 'texImage2D' on 'WebGL2RenderingContext': The video element contains cross-origin data, and may not be loaded.`

How to fix this?

The response header for my video delivered seems to be OK:

1. Access-Control-Allow-Headers:
   DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range
2. Access-Control-Allow-Methods:
   GET
3. Access-Control-Allow-Origin:
   http://localhost:3000
4. Access-Control-Expose-Headers:
   Content-Length,Content-Range
