Livestream Clients

This section shows you the three different methods of livestreaming Omniverse Isaac Sim. Before running a livestream client, make sure that Isaac Sim app is loaded and ready. It may take a few minutes for Isaac Sim to be completed loaded. To confirm this, look out for this line in the console or the logs:

Isaac Sim Headless Native App is loaded.

You may see other lines depending on which mode was launched:

Isaac Sim Headless WebRTC App is loaded.
Isaac Sim Headless WebSocket(Deprecated) App is loaded.
Isaac Sim App is loaded.
Isaac Sim Python App is loaded.

Note

Only one method of streaming can be used at a time for each Isaac Sim instance.
To cleanly exit the app. Click the File menu then click Exit.
Livestreaming is not supported when Isaac Sim is run on the A100 GPU. NVENC is not included in the A100.

Omniverse Streaming Client

Omniverse Streaming Client is the recommended streaming client to view Omniverse Isaac Sim remotely on your desktop or workstation without a powerful GPU.

Note

A GPU is required to use Omniverse Streaming Client.

To connect to a local headless instance of Omniverse Isaac Sim, use IP 127.0.0.1.

Each Omniverse Isaac Sim instance can only connect to one Omniverse Streaming Client. Connecting to an Omniverse Isaac Sim instance that is currently serving a Omniverse Streaming Client will result in an error for the second user.

Errors may still be displayed in the logs even when running Omniverse Streaming Client is successful. This will be cleaned up later on. Right now, the logs would be useful for debugging. See: Known Issues - Errors.

The 1280 x 720 (HD) resolution may not work for AWS EC2 instances.

Omniverse Isaac Sim or the Omniverse Streaming Client may hang when shutting down from the File menu. See: Known Issues - Hang.

The following ports need to be whitelisted: TCP/UDP 47995:48012, TCP/UDP 49000:49007, and TCP 49100.
