I am trying to test the v4l2_camera sample (latest release 20210609-e336b5195 at the time of writing). Sample Applications — ISAAC 2021.1 documentation
I followed the instructions on the getting started guide to deploy the application on my XavierNX. I’m running Jetpack 4.5.1 as instructed by the documentation. Getting Started — ISAAC 2021.1 documentation
I have successfully deployed the algorithm on my Jetson. Here is the terminal output:
v4l2_camera deployment (21.7 KB)
Then I SSH’ed into my Jetson and ran the algorithm. Here is the terminal output.
v4l2_camera run (9.2 KB)
As you’ll realize, there’s an error message.
2022-01-13 14:08:01.375 ERROR packages/sensors/V4L2Camera.cpp@141: [V4L2Camera] Format request failed with error: Invalid argument.
Then I started Nvidia Sight on my host machine. However, I don’t see the camera feed. It says “This channel is currently empty.” But why? There’s only one camera connected to Jetson, I can find it with “ls /dev/video*”. Shouldn’t the algorithm just find the camera automatically? How can I fix this?
P.s., I can confirm that the camera works as is. I used GUVCviewer to check it.
