Question IP camera footage not displaying over mesh renderer

I'm doing this experiment of mine where the Unity project uses the AR/XR (ARFoundation) Kit. I had no problem setting everything up in Unity itself, as the documentation provided was pretty clear.

Now to the IP Camera connection part. I've searched through various pages around the internet, from here on Stackoverflow to several Unity forum threads and managed to have the code below that is supposed to fetch the video stream via URL while also processing the image.

When I start the program, instead of showing the footage, a plain white screen appears, like seen in the image below. No compiling errors are shown up in the console either.



I'm using an assisting iSpy software to help me generate a link for the camera. The IP camera I'm using is an AHD x001woxytn.

I'm just not sure if it's from the URL itself or if it's something wrong with the code, which is down below:
