Capture frames from deepstream with a tracker - RuntimeError: get_nvds_buf_Surface: Currently we only support RGBA/RGB color Format

I’m new to deepstream and I’m trying to capture frames from the deepstream_nvdsanalytics.py example.
I added another nvvidconv to convert to RGBA, but for some reason it is still showing this error: “RuntimeError: get_nvds_buf_Surface: Currently we only support RGBA/RGB color Format”. My guess is that I linked the elements in the wrong order, but I don’t know what’s the correct one.

You need to add the nvvideoconvert before the nvdsanalytics plugin.

Thanks, that makes sense
