I’m using python deepstream app and the input image size is 1920x1080 and the image size for inference is 1248x384 and the image size for tracker is 640x384.
I would like to see how the input images get resized by the elements “nvinfer” and “nvtracker” to get an understanding of the image being processed.
I tried to attach a probe method for the “nvinfer” element’s sink and source method, but I don’t see the resized(1248x384) image rather I see the full(1920x1080) image.
Could someone help me to visualize/store the resized image by the nvinfer element?

This requires modifying the code of nvinfer(/opt/nvidia/deepstream/deepstream/sources/gst-plugins/gst-nvinfer).

You can refer this FAQ.
