Hardware Encoding GUID (Jetson Nano)

Hi,
Video Codec SDK is specific to desktop GPUs and not supported on Jetson platforms. For hardware encoding, please use gstreamer or jetson_multimedia_api. You already have the link to gstreamer user guide. For jetson_multimedia_api, please check
https://docs.nvidia.com/jetson/l4t-multimedia/index.html
After the installation, you can see samples in

/usr/src/jetson_multimedia_api

For WebRTC, please check
