I would like to clarify that I am a first-time user of the Kit.
I am following the link WebRTC Livestreaming: "Not Found" error when accessing streaming client .
I’ve enabled the extension described in that post.
First, I tried the method described above, but unlike the video, the
.\repo.bat launch -n my_company.my_usd_composer_streaming.kit -- --no-window
part didn’t work. So I tried the
.\repo.bat launch -n my_company.my_usd_composer.kit -- --no-window method.
However, I can’t connect, although I’m not sure if it’s a port issue.
My ultimate goal is to integrate the video in real-time with a web page created in Next.js.
Please help.
PS. I’m running this on Windows 11, not Docker.

Hi there and thanks for posting. If you leave your kit filename as default, then yes,
.\repo.bat launch -n my_company.my_usd_composer_streaming.kit – --no-window
Should work fine. What error were you seeing? Make sure you are running that command in the kit app streaming folder.
You should have also run the “npm” command for the streaming sample, as well.
You sent a screenshot of your web interface, but it is waiting for a response with the “Next” button. When you did that, what error were you seeing?
Thank you!
I found the cause. The reason was that I had to press Space+Enter for Streaming in Template New, instead of Enter.
Thank you so much for your help.
I’m using Viewer.streaming. What’s a more efficient way to adjust parameters in real time after integrating a website?
I understand the messaging method. Is there any documentation that might be helpful?
Ah yes, that silly spacebar gets everyone. Sorry to hear that. I have told them to get rid of that !
Glad you solved it !
I have one last question. I’m currently working with Kit, but I’m thinking of switching to Isaac-Sim. Is the process the same?
No, Isaac Sim has its own streaming system at this time. You will have to follow those specific instructions.
Livestream Clients — Isaac Sim Documentation
First, I’d like to apologize for the delay.
I’ve successfully live streamed to the web using the kit. I’m planning to enable multiple users to simultaneously view the webcast from anywhere in the future.
The link doesn’t seem to allow simultaneous viewing, but I’m planning to use force fields to simulate liquids. I don’t see any reason to insist on Isaac-Sim.
Unfortunately, we cannot stream to multiple users right now, using the web viewer sample code.
To support this currently, you would need to configure the Kit application to emit multiple streams. Please see Overview — omni.kit.livestream.app for details on how to do that.
Each individual client would then need to connect to one of the unique signalPort which was defined in the settings for your Kit application.
Thank you for your reply! First of all, real-time integration is currently possible with a website built with Next.js, not Web-Viewer-Sample.
Looking at the link you sent, if only one client can connect per instance,
then I guess I could create multiple instances and distribute them to users?
That is one way of doing it yes. Multiple instances, for multiple users. Can I ask exactly what you are trying to do?
First of all, I apologize for the late reply.
I’m trying to create a 3D point cloud, assetize it, and use it to create training data through simulation.
I’m also trying to integrate it into the web, enabling manipulation and observation.
