I’m currently working with PipeTuner for optimizing a pipeline, and I’m looking to integrate a preprocessing step into my configuration. I’ve reviewed the documentation but couldn’t find any specific information on how to incorporate preprocessing tasks. Any suggestions would be greatly appreciated.
Thank you!

Hi PipeTuner user, could you provide more detailed use case?
Are you using DS Gst-nvdspreprocess plugin for preprocessing? Do you want to tune any preprocess parameters?


Can you provide the information we are asking for?

Hello, I’m using the Gst-nvdspreprocess plugin for preprocessing in a GStreamer pipeline, with a model size of 320x320. My video stream size is 3840x2160. I want to add ROI to the video stream during preprocessing.

Do you want to tune any preprocess parameters?

No I don’t want to tune any preprocessing parameters. Let me rephrase the question. For pipetuner we use a gstreamer pipeline where nvstreammux, nvinfer and nvdsosd elements are used. I wanted to include nvdspreprocess before nvinfer, so that the pipeline is closer to my use-case and the tracker is more accurate.

PipeTuner uses deepstream-app pipeline for tuning by default. The deepstream-app supports preprocess with nvinfer DeepStream Reference Application - deepstream-app — DeepStream documentation 6.4 documentation. There is a sample configuration file /opt/nvidia/deepstream/deepstream/samples/configs/deepstream-appsource4_1080p_dec_preprocess_infer-resnet_preprocess_sgie_tiled_display_int8.txt

What kind of ROI do you want to add in the configuration?
