C# - Stream from IP camera over 3D Plane object

Hello i made a program with Unity3D that "project" the image of an ip camera over a 3D object, a plane..

The script is working well with streams i got from the internet but i have problems with my Panasonic WV-SW458.

Do not know why because i get the right stream on the internet and in the VLC with both the internet camera and my Panasonic.

I'll attach my code , maybe i'm missing something that, at the moment, i cannot see...
