My application fails to stream during local validation
Below are a few potential reasons why you may encounter this, including troubleshooting steps.
Host desktop is being streamed to the browser
If you are seeing your own desktop window streamed in the browser, it is likely due to an overlapping nvstreamer-server running. Execute the following command to display all instances of nvstreamer:
ps aux | grep nvstreamer
Look for a duplicate nvstreamer process as shown below. In this example, the top one is the conflicting process:
nvidia 2772 0.0 0.0 7372 2920 ? Ss May13 0:00 /bin/bash /opt/nvidia/nvstreamer/bin/startnvst.sh nvidia 2780 0.3 5.4 10220164 1779680 ? Sl May13 11:56 /opt/nvidia/nvstreamer/bin/../server/nvstreamer
You may kill this process or disable the nvstreamer server by invoking the following command:
systemctl --user stop nvstreamer-server
To fully disable the server, run this command:
sudo systemctl disable nvstreamer-server
You may need to stop and re-launch the Docker container using this command:
docker container stop CONTAINER_ID docker run --runtime=nvidia --gpus all --net=host usd-viewer
Black viewport screen: Application not yet ready
This can occur if the shaders are still being compiled when the Web Client connects to the streaming Kit application. Depending on the number of unique shaders, compiling may take several minutes.
Once all shaders are compiled and the application is ready, you should see the message RTX ready
in your container’s terminal.
