Playing video with chromakeys


I’m been trying to use A-Frame and Universal SDK to have Image Tracking.
But currently I’m facing a problem that I can’t make my video be transparent (On the chromakeys).

I have imported this plugins on my HTML.
aframe-chromakey-material - npm (

But either it won’t work or failed to load my webpage.

Here are my codes:-

<a-video src="#Green_Screen" width=“4” height=“2.25” position=“0 0 0.1” scale= “0.8 0.8 1” material=“shader: chromakey; src: #video; color: 0 0 1” webkit-playsinline playsinline></a-video>

Did I did it right?
