The constructor doesn't seem to behaving properly on videoTextures.
I can't seem to disable the mipmaps or change the sampling mode. However, invertY is working probably. I also get an error if I try and feed in the urls/url as an object stating that urls.ofEach is not a function.
Here is an example:
