Hi @abdallah0012,
Sorry for my late response.
Normally, usb webcamera exists in either /dev/video0
or /dev/video1
.
ls /dev/video*
If you find /dev/video0
, set the config.yaml to camera_input: 0
.
If you find /dev/video1
, set the config.yaml to camera_input: 1
.
Hello when i run this: python "run_stream.py" with my jetson xavier and logitech c930e. note that have this in config.yml (camera_input: 1 ) i have this error ;
run_stream.py:59: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe.
