Official Unity Render Streaming Introduction & FAQ

Thank you for your reply

 

Hello,
How can I change the port of the Signaling URL?
The server can be changed with webserver.exe -w -p 81,
RenderStreaming(Script) Signaling URL ws://localhost:81
Will be ignored and will be the default (80).

 

I am following the documentation to setup my project. The documentation states to click on the webserver.exe
Whenever I try to open the 'webserver.exe', it closes immediately. Does anyone know why this happens?

 

UnityRenderStreaming 3.1.0-exp.2
So how can I change the port number?

 

I was able to resolve my problem by removing the default website in IIS (this was using port 80)

 

Hello,

I am having trouble understanding how does the bidirectional example works. As far as I know two RTCPeerConnections are required for bidireactional stream. One for the local stream the other for the remote. But in the sendVideo.js example only one Peer class is initialized and assigned to this.pc. Can anyone explain how this works?

 

What I want to know is not the Web Server side. I would like to know how to change the port number on the application side that runs on Unity.

 

Thank you very much for your answer. I referred to this answer and it seems to have improved a little, but I still feel stuck. I want to know if there is an upper limit to encoding. MaxBitrate in ChangeVideoParameters or if there is an upper limit to renderStreaming. I want to make full use of my bandwidth and CPU

 

Hi, Good project and has huge potential. Thank you !

I have been trying to work with it for a week now. I integrated my data and the project worked fine as expected. I connected my laptop to my mobile-internet. Started the application from my laptop and the application worked in both in my laptop and android-mobile.

But today when I tried the same, the application starts in desktop. But in my android-mobile, when I click the play button, the UI-buttons appear, but after a while it goes back to the play button screen. I checked the console both the browser and unity consoles , there are no suspicious errors.

Edit : API request are successful too. It is the moment the when suppose the rendering should start, it goes back to the play-button screen

Edit 2 : I checked it another mobile. This works. But still not in my mobile. I cleared the caches too.

 

Hello @kazuki_unity729

Do you have a planned date to release 3.1.0 as the stable branch?

Thanks

 

Thank you very much for your reply. I'm sorry I'm not good at English.

When I said stable branch, I meant the official release package, not the experimental package.

Is there any problem in using the exp version for commercial real service?

 

Hello,
I want to use the same data channel as the Input system to send some JSON data to the server, but the server crash at the end, is there a better way to solve it?

Client -> Arfoundation4.0 Scenes
Server -> Broadcast Scenes

Code (CSharp):

1.  
2.     // In Sender.cs file
3.     public class MyClass
4.     {
5.         public string name;
6.         public string time;
7.     }
8.  
9.     class Observer : IObserver<InputRemoting.Message>
10.     {
11.         private RTCDataChannel _channel;
12.         private string json;
13.         public Observer(RTCDataChannel channel)
14.         {
15.             _channel = channel ?? throw new ArgumentNullException("channel is null");
16.         }
17.         public void OnNext(InputRemoting.Message value)
18.         {
19.             if (_channel.ReadyState != RTCDataChannelState.Open)
20.                 return;
21.             byte[] bytes = MessageSerializer.Serialize(ref value);
22.             _channel.Send(bytes);
23.      
24.             // Add JSON data
25.             MyClass myObject = new MyClass();
26.             myObject.name = "Test";
27.             myObject.time = DateTime.Now.ToString();
28.             json = JsonUtility.ToJson(myObject);
29.             _channel.Send(json);
30.         }
31.  
32.         public void OnCompleted()
33.         {
34.         }
35.         public void OnError(Exception error)
36.         {
37.         }
38.     }

 

I tried it. However, the port number I entered is ignored and defaults to 80.

 

Check the "Run On Awake" is select after change the port number.
It works for me.

 

please install node enviroment

 

It was no good.
As a result of investigation
Assets\Samples\Unity Render Streaming\3.1.0-exp.2\Example\Scripts\SceneSelectUI.cs
The value of s_signalingAddress is hard-coded inside,
It turns out that it will be overwritten.

 

Certainly, it seems that you can change the port during execution by starting from Menu.unity. I wanted to try Multiplay.unity, so I was launching it.
solved.

 

Hi,
I use Unity Render Streaming 3.1.0-exp.2 Unity 2019.4.26
I use one Unity Editor send microphone audio data and other Unity Editor receive data.But the delay will be about 500 milliseconds.
I do not know how to reduce this delay!
Thanks!

 

Excuse me, if I have a mouse click event on an object, then the result is displayed through the GUI. I need to be able to operate in the editor, but also in the browser, which way do I need to use in this case.

 

I'm having some issues with the Broadcast sample scene and using the web browser as a client.
I'm wanting to click into the scene using the html client and that mouse click should cast a ray from the camera to the object the user is clicking. I've tried implementing this but i'm getting weird results with the raycast. Any tips?

 

[BUG] Received screen upside down (up-down-reversed) with "Screen Stream Sender" on Linux (Ubuntu 20.04)

I tried the https://docs.unity3d.com/Packages/com.unity.renderstreaming@3.1/manual/sample-broadcast.html sample on both Windows and Linux.
On Windows it's good.
But on Linux I saw the received screen (in browser) was upside-down (up-down-reversed), see the screen shot below.

To Reproduce
Steps to reproduce the behavior:

1. Follow https://docs.unity3d.com/Packages/com.unity.renderstreaming@3.1/manual/sample-broadcast.html to run the sample with latest WebRTC package and webserver application, on Linux (I was using Ubuntu 20.04 desktop)
2. Open link "http://localhost/receiver/index.html" in browser (I was using chrome).

Expected behavior
The received screen in browser is consistent with the desktop screen.

Screenshots


Environment (please complete the following information):

• OS: Ubuntu 20.04 LTS Desktop
• Browser: Chrome
• Unity Version: 2020.3.25f1
• Package version: 3.1.0-exp.2

Additional context
Looks this issue only happens to "Screen Stream Sender", and doesn't happen to "Camera Stream Sender".
Also, when I built my own unity project with WebRTC package, the same issue happened. So looks it's not an issue of the sample, but a bug of the package or the webserver app.

I also posted this issue here: [BUG] Received screen upside down (up-down-reversed) with "Screen Stream Sender" on Linux (Ubuntu 20.04) · Issue #618 · Unity-Technologies/UnityRenderStreaming (github.com)

 

I did my own shader to rotate WebCamTexture then I'm creating VideoStreamTrack and video works well in portrait mode but there is problem when i'm trying stream video in landscape mode. Rotation is ok but aspect ratio is still in portriait mode. Is there some option to change VideoStramTrack texture resolution runtime or some other way to keep proper resolution to device rotation???

 

Hello,my version is unity 2020.3.23f1,Unity Render Streaming 3.1.0-exp.2 depends on WebRTC 2.4.0-exp.5.When I run the video stream demo, the received video on web is extremly vague.I have tried to change resolution and anti-aliasing,but nothing changes.So I guess the video codec leads to this the problem,what can I do to change the webrtc codec from VP8 to VP9 through chrome?Does some way else to improve the video quality?

 

I never use the Hardware Encoder Support from the beginning,just as the default setting,and I just forgot to say my unity would crash if I use Hardware Encoder Support.

 

I closely watched the broadcast demo's results to find that the video quality seems to be equally vague to my own project's results,so could I change my project to hdrp template to solve the problem

 

Hello!
There were some problems with cloud rendering
Such as:
When running Unity and opening the server, there is no screen in the browser, but the mouse wheel and buttons are available.
The computer system is Windows 7, will it have any impact on unityRenderStreaming?
Have what good solution method!
Thank you very much!

 

I recently find that only when I move the camera which employs render streaming ,the video on web will be extremely vague.Can I solve the problem at present?

 

Hello, I am using Unity 2019.4.33 and com.unity.webrtc 2.4.0-exp.5. When I use one Unity to send audio, the other Unity receives audio. I stop the sending side and at this point when I stop the receiving side Unity crashes on the receiving side. I can't find the reason? I see that it has been fixed in 2.4.0-exp.6, but it still appears in my test

 

Hi, here is the crash log. Thank you

 

• I sometimes can't connect, report this error
  

 

Hi
I am following this tutorial (

) and successfully running application
and having two player connected fine. Now I want to render a webcam texture on each player cube and don't know what to do next.

 

has anybody deployed the signaling server in Google Cloud or somewhere? Just tried with Google Cloud but I'm having issues making the NodeJS app run.

 

I just found there was a problem with dependencies and filed this bug:
https://github.com/Unity-Technologies/UnityRenderStreaming/issues/662

By creating a new repo with the contents of WebApp, and making the Procfile for running in Heroku, I was able to deploy the signaling server and use it with HTTP signaling successfully.

Would be nice to have WebApp as a separate repo so that we can make our adaptations but still get new features or fixes from the Unity side. But I understand that might be asking for too much
