I don't think this will solve the problem but anyways there is no driver built for the card you have.   Also I don't think the GT220 has NVENC but I could be wrong about that, but what I also think don't work that the "old" driver version of 'nvidia-smi' isn't compatible with the Plugin from @b3rs3rk.   Wouldn't it be better to buy a used GTX1050 or something similar that is capable of 4K encoding and decoding?
