Nvidia Jetson Nano two Webcams with same name

I have to Logitech C720 cams which name is not a valid identifier since the cam gets the name from the Card-Type. The method camlist returns both cameras: one on /dev/video0 and the other on /dev/video1. Since the camera method uses the camname for analysing the device index, the sscanf function returns an error because to names are available.

My solution for the Moment is to rewrite the function, but this issues should be fixed in future releases.

Hi Matti,

The camera function enables the user to create a camera object based on the card-type. To create a camera object for the desired camera, provide the Card-type(Ex '/dev/video0') in place of 'VideoDeviceID' in the below syntax.

camObj = camera(hwObj, cameraName, resolution, 'VideoDevice', '<VideoDeviceID>');

This duplicates what @Sai Ram Sristi already posted.

If the point was to move Sai's posting to be an Answer, then the moderators have tools to do that.
