Hi,
The steps should work fine without building the source manually:

$ echo "deb https://repo.download.nvidia.com/jetson/ffmpeg main main" |  sudo tee -a /etc/apt/sources.list
$ echo "deb-src https://repo.download.nvidia.com/jetson/ffmpeg main main" |  sudo tee -a /etc/apt/sources.list
$ sudo apt update
$ sudo apt install ffmpeg

After executing the steps, you should see the hardware decoders:

nvidia@nvidia-desktop:/$ ffmpeg -decoders | grep nvv4l2
