Open KlingOne opened 2 years ago

KlingOne commented 2 years ago

Package version

2.4.0-exp.7

Environment

* OS:Windows and Linux
* Unity version:2021.3.3f1

Steps To Reproduce

Build and the VideoReceive Sample with Dedicated Server as build Target (Windows or Linux)

Current Behavior

App Crashes when initializing WebRTC

Expected Behavior

App does not crash

Anything else?

This used to worked on 2.4.0-exp.4

We have not supported dedicated server platform yet, but the app crashes is weird. I think the dedicated server don't have the video/audio rendering feature.

@KlingOne Is it related your issue? https://github.com/Unity-Technologies/com.unity.webrtc/issues/734

@karasusan I don't think so. For me the samples work fine in the editor and in standalone builds. Only when building as Dedicated Server the crash occurs. I also tried the develop brach with #741 and the error still persists.

But the problem could be similar, since Dedicated Server builds do not initialize a graphics device at all as far as I know.

karasusan commented 2 years ago

@KlingOne Sure. I will check it on the platform. I am curious how you use it on the Dedicated server.

KlingOne commented 2 years ago

@karasusan We are using the dedicated server as signaling server so that every player that joins our game automatically gets added to a WebRTC group call

karasusan commented 2 years ago

@KlingOne This is only my opinion, I think websocket is better than webrtc for signaling server.

KlingOne commented 2 years ago

@KlingOne For sure. But for us it was the fastest way to implement it since the Server was allready up and running.

I still wanted to let you know about the crash.

karasusan commented 2 years ago

@KlingOne We added the ticket for the issue into our backlog, but I cannot promise when it will be fixed.

We are seeing this problem as well. Not using a dedicated server build. It will crash when calling WebRTC.Initialize();, and this happens when trying to run inside the Unity editor.

@jonkelling Thanks for reporting your situation. Can you share your environment ( platform, WebRTC package version, Unity Editor version) or Editor.log ?
