How do I debug the code data pipline of deepstream?

[autodrive2022]

In the process of building the whole pipeline, I want to debug, for example: how to see what the output stream data is after Nvinfer element loads the engine?
Is there a tool or a code demo that I can refer to, so that I can observe these variables and know what they mean at the same time.

You can add probe function at any plugin to get the data you want. You can refer the osd_sink_pad_buffer_probe from the demo source deepstream_test1_app.c. You need to know some basics of gstreamer.
