Sharedmemory

Hi
Just trying to pass a videoin texture between
2 Vvvv instances on the same computer
My camera only send 640x480@30fps(mpeg4)
The received image is buggy
Changing the bit per pixel pin to value 8
Let me see a. Part of the image
But still repeated/superposed
So i wonder if the shared memory
Node only support square formats?

SharedMemory (DShow9 Transforminplace)
is the answer

if i want to optimize the framerate in my main patch
does it make sense to use a second instance of vvvv with theSetProcessAffinityMask (Windows)
for a videoin + SharedMemory (EX9.Texture) patch
???
