The Documentation page Video As A Texture | Babylon.js Documentation has 2 examples:
https://playground.babylonjs.com/#ZMCFYA#2
and
https://playground.babylonjs.com/#CHQ4T#1
In both examples the videotexture is flipped horizontally.
To correct it one needs to add:
ANote0VideoVidTex.uScale = -1;
like here - https://playground.babylonjs.com/#ZMCFYA#81
Should I make a PR with corrected PG links?
