I want to use the Gst-nvvideoconvert for cropping the video input before going to the inference. But I don’t know how to use it. Am I just going to edit the config file and add new properties or am I going to edit the code of deepstream? Also any advice for cropping the video woud be great (I want to get right half side of the frame as ROI)! Thank you!

nvvideoconvert has already support cropping video(src-crop, dest-crop). You can set the property in your application.

For basic gstreamer programming, please refer to https://gstreamer.freedesktop.org/
