do you mean want to draw on frame before nvosd ?

  1. Nvosd can draw polygons ,please refer to Gst-nvdsosd — DeepStream 6.1.1 Release documentation
  2. you can add display meta in probe function, nvosd will process these meta, please refer to osd_sink_pad_buffer_probe in deepstream-test1.
  3. some code in probe function, Push frame back to DeepStream pipeline inside a probe function
