Control the Anamorphic pixels

Hi,

are some UI variable in the HTML5 player to stretch the image to a 16:9 when you have a 4:3 video prepared to be stretched (typical with sources from TV SD) . Maybe a variable to control the Anamorphic or pixel proportion?

I saw the stretchVideo UI variable but apart from it's only for legacy I'm not sure that it could be useful.

thanks
