@rsardal Hi, which architecture in raspberry pi are you using? ndi-python only support for aarch64 in raspberry pi, so should select 64bit os. Please check the your architecture with the following command.

uname -m

@buresu Ahh mine is armv7l, so looks like I won't be able to use it! Is there any support for 32 bit os coming?

Regardless, I love the library and thanks for the great work!
