[Mitra]

I want to try Avisynth+ CUDA Build, this is my script :

LWLibavVideoSource("input.avi")
OnCUDA()
KTGMC()

but gets the following error:
This Avisynth does not support memory type 2 (CUDA)

And if I delete OnCUDA(), it gets this error:
Unhandled C++ exception!

my machine : i7 10700k, GTX 1660, Nvidia driver 472.84 standard
