There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
please refer to osd_sink_pad_buffer_probe of deepstream_test_1.py, it will loop every frame of batch, then call “pyds.nvds_add_display_meta_to_frame(frame_meta, display_meta)” to add one displaymeta to each frame.
