Can you share you configure file and which DS sample do you used?

nvpreprocess config

nvinfer config

The DS sample is deepstream-preprocess-test, and i change the nvinfer to a custom-classify model, which caused the NvDsObjectMeta is None

I meet the same error as below,while input-tensor-meta=1, the classifier result was none, can you give me some advice?
Cannot obtain the pgie classifier result using nvpreprocess - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums

Preprocess ROI have one green box on the picture. Can you see it?

I did not draw the result on the image, but i can get the value of ROI in the NvOSD_RectParams struct.

We have many samples, such as: /opt/nvidia/deepstream/deepstream-6.1/sources/apps/sample_apps/deepstream-preprocess-test/test/config_preprocess_yolo.txt Can you have a try it?

There is no update from you for a period, assuming this is not an issue anymore.
