hi,

I created a new json file to just record file via recording tool. Basic one. I got that error. Here my json code:

Dear makman4,
We do not support usb cameras via recording tool currently and protocol for camera sensor should be camera.gmsl(Please check file:///usr/local/driveworks-2.0/doc/nvsdk_html/rigconfiguration_usecase0.html). Please check sample_camera_usb(file:///usr/local/driveworks-2.0/doc/nvsdk_html/dwx_camera_usb_sample.html) for recording on x86.
