I am getting this error when using videos-panorama
Dom Exception: Failed to execute \'texImage2D\' on \'WebGLRenderingContext\': The video element contains cross-origin
The concept of "CORS" is explained here: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
There is an earlier thread here on Stack-Overflow discussing this here: enable cors in .htaccess
To boil it all down, most webservers are happy, if you just supply them with a two-line file named ".htaccess", containing these 2 lines:
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
