Hello, I tried running the sample_dnn_tensor (Driveworks-4.0) with camera AR0231 as input. But it seems that the exposure and
white balance are always constant. How can I set the auto exposure and white balance mode? Thank you.

Dear @Chris1234888,
The sample does not have parameters to control exposure and white balance. Note that, DW APIs does not have APIs to control these parameters. May I know do you see any issue with your camera when using the sample?

@SivaRamaKrishnaNV
Thank you for reply. The main issue is that the Drive AGX Xavier cannot make auto exposure so the image is always dark when the light condition bad.

Do you mean that we can only use fixed exposure and white balance settings in DW?
