Missing tegra_multimedia_api

I just setup my Jetson TX2 as per https://tm3.ghost.io/2018/07/06/setting-up-the-nvidia-jetson-tx2/ version 3.3 of Jetpack. I have the jetson_clocks.sh file in my home folder, but I’m missing the tegra_multimedia_api folder. What do I need to do to get it to load?

If you install [Multimedia API package] via Jetpack, it should be under /home/nvidia/
