Usage of RTSPwriter

Hi, I attempted RTSP streaming from isaacsim2023.1.1 following the instructions on the following page, but it didn’t work out well.
https://docs.omniverse.nvidia.com/isaacsim/latest/replicator_tutorials/ext_replicator-character/writer_control.html

  1. The RTSPwriter was found in omni.replicator.character.core instead of omni.replicator.core, so I added the import statement and wrote the script as follows.
import omni.replicator.core as rep
import omni.replicator.character.core as repchar

render_products = []
render_products.append(rep.create.render_product("/World/Camera",resolution=(1024, 1024)))


writer = rep.WriterRegistry.get("RTSPWriter")
writer.initialize(device=0, annotator="rgb", output_dir="rtsp://<my IP address>:8554/RTSPWriter")
writer.attach(render_products)
  1. Additionally, I enabled the following two Extensions in the Extensions Window.
    image

  2. I positioned the cone mesh and camera.

As a result, the logs from isaacsim’s console and terminal appeared as follows, but it doesn’t seem to be functioning properly. Could you please provide guidance on the correct procedure?
