On my desktop i can run encoding tests and use nvidia-smi to see the gpu usage.

How can i do this on the jetson?

I ran ffmpeg with and without HW acceleration (see https://github.com/jocover/jetson-ffmpeg).
I can only tell that CPU utilization improved with HW acceleration (180% vs 240% out of 800% on 8 cores). RAM usage also improved (dropped) by 100MB.
b.t.w: encoding is not done with the GPU, but you can see its statistics with tegrastats.

Hi, I tried to install the Jian ffmpeg component, but with little success, I downloaded the image from the nvidea nv-jetson-nano-sd-card-image-r32.3.1 site and then I hatto update and upgrade and followed the guide but when I go to cmake … displays the following error

CMake Error: The source directory “/home/carlo/jetson-ffmpeg/build/VAR:type=LIB_V4D2” does not exist.
Specify --help for usage, or press the help button on the CMake GUI.

how can i solve?
