Camera
Testing MIPI-CSI2 cameras
Before running any of the pipelines below make sure you have camera(s) connected. AM6 family of processors uses gstreamer as multimedia framework. Please refer to https://gstreamer.freedesktop.org/
Camera Probe
Run the following command to see if you have the camera(s) detected
# v4l2-ctl --list-devices
This should produce the following output
j721e-csi2rx (platform:30102000.ticsi2rx):
/dev/video0
/dev/video1
/dev/video2
/dev/video3
/dev/media0
The camera interface is /dev/video0
