Loading movie runtime with WWW class

Hi everyone,
I would like to load movie via WWW class. I’ve tried to load a sound and it works. I check the manual, I copy/paste made some changes, but nothing. I also tried to add directly in Unity without the download and again, it works.

I’ve tried .avi, .ogg, .mov. … nothing.

var myWWWImageAPI = new WWW(“http://www.savie.qc.ca/CVJE3_DEV/Videos/sample.avi”);

yield myWWWImageAPI;

var myMovie:MovieTexture = myWWWImageAPI.movie;

var movieText = visualQ.GetComponent.<UI.RawImage>();

movieText.texture = myMovie;

var movie:MovieTexture = movieText.texture as MovieTexture;

movie.Play();

anyone can help ?
Thanks

I have Unity 5.1.1f1 free
