Can I decode video using NVIDIA Codec SDK?

Can I use https://developer.nvidia.com/nvidia-video-codec-sdk on Jetson Nano? I don’t have mine yet, and I’m evaluating its capabilities before buying

No, the NVIDIA video codec SDK is for desktop parts.

However, the Jetson SDK comes with example implementations for hardware video decode, based on the Video4Linux2 standard. The v4l2 codec can hardware encode/decode any of the supported stream formats, which varies a bit between the various Jetson levels – the Nano is based on old Maxwell chips, and thus have less wide codec support compared to the latest-and-greatest like AGX Xavier.
