Please provide complete information as applicable to your setup. **• Hardware Platform (Jetson / GPU)**Orin Nano • DeepStream Version 6.3 **• JetPack Version (valid for Jetson only)**5.1.3 I’m trying to plot rectangle on gst-dsexample plugin. I have segmentation fault when cv::rectangle api is …

Could you refer to our source code in gstdsexample.cpp? /* rectangle for cropped objects */ crop_rect = cv::Rect (crop_rect_params->left, crop_rect_params->top, crop_rect_params->width, crop_rect_params->height);

That is cropping rectangle. I am plotting a rectangle on image using opencv’s api cv::rectangle

If you just want to draw the rectangle on the image, you don’t have to use the opencv or gstexample plugin. You can just use a probe function and set some parameters to our NvDsDisplayMeta like deepstream-test1.

[image] yuweiw: NvDsDisplayMeta My main intention is I like to plot rectangle on the saved image. I have earlier posts like plotting bounding box on saved image , in which I tried to shift the position of gst-dsexample plugin to after osd plugin. But doesn’t succeed. @ rajupadhyay59 suggeste…

The nvdsosd plugin draws the rectangle to the image. Is your dsexample plugin after the nvdsosd plugin in your pipeline? There are many ways to draw the rectangle on the image. But if you don’t use the opencv to draw that by yourself, you need to save the image after the nvdsosd plugin.

No. I still not succeed putting gst-dsexample after osd plug-in. Any sample for that? I tried but didn’t work. Thanks

Ok thanks. Let me check. Thanks for the sample.
