I am testing the Sensor/Camera_USB sample application and it seems that only supports USB cameras with YUYV 4:2:2 output? I have a camera which supports UYVY and MJPEG.

Just wondering if it is possible to develop a plugin to support UYVY ?

Thanks

Dear @jpvans,
Plugin development is not possible for camera. May I know camera details and what error you encounter?

I am using a E-ConSystems Camera See3CAM_CU135

The sample application is the following:

Dear @jpvans,
Yes UYVY is not supported. Also, I notice you seems to be using DW 3.0 release which is not part of Devzone release( DRIVE SW 10.0 has DW 2.2)

Thanks for confirming. I am using both DW 10 and Nvidia Drive 3.0
