Two cameras are connected to MIPI0 and MIPI4
In dts (which will be below) these cameras are defined.
I run the script
gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM), width=(int)1920,height=(int)1080,framerate=60/1' ! nvvidconv flip-method=0 ! 'video/x-raw, format=(string)I420' ! ! xvimagesink sync=false
Getting image from MIPI4 camera.
Now run the script
gst-launch-1.0 nvarguscamerasrc sensor-id=1 ! 'video/x-raw(memory:NVMM), width=(int)1920,height=(int)1080,framerate=60/1' ! nvvidconv flip-method=0 ! 'video/x-raw, format=(string)I420' ! ! xvimagesink sync=false
And again I get the image from the MIPI4 camera.
Two windows in which capture images from one camera which is connected to MIPI4.
Now if you remove from dts all that is connected to the camera on MIPI4 (disconnect it)
The camera with MIPI0 starts working
Logs attached.
