Package version

3.1.0-exp.5

Environment

* OS: ubuntu18.04
* driver version : 470.141.03, CUDA version 11.4 
* GPU:Tesla T4 GPU * 4
* Unity version: unity2020.3.41f1
* WebRTC: 3.0.0-pre.4
* Graphics API: auto
* Browser: chrome 110.0.5481.77(officual build)(64bit)

Steps To Reproduce

1.in a blank new unity project, install renderstreaming package and import samples. 2.download and launch the web application like: sudo ./webserver -w -p 88 3.open chrome and goto this page, the web page looks normal. 4.in unity, open renderstreaming broadcast sample scene, in RenderStreaming script, set it to websocket and ws://localhost:88 5.in unity, click play and run, looks ok and logs showing WS connected. 6.go to chrome the webpage and goto receiver sample page. 7.click play and start to streaming

Current Behavior

result: unity crash immediately, some last log looks like:

Expected Behavior

expected: unity runs correctly and start streaming to the webpage.

Anything else?

Any idea or Anywhere to check the unity crash log ? a bug has been reported and uploaded. Thanks

Can you check what the graphics driver is installed? I assume that the issue relates the graphics driver for Linux.

[flankechen]

@karasusan it's a driver version : 470.141.03, CUDA version 11.4 Tesla T4 GPU * 4

[karasusan]

@flankechen It looks no problem. How about Unity player log?

[flankechen]

@karasusan here is some logs, and BTW, a unity bug report is uploaded https://unity3d.atlassian.net/servicedesk/customer/portal/2/IN-31844 https://issuetracker.unity3d.com/issues/linux-render-streaming-crash-on-getrendereventfunc-when-connecting-receiver-sample-to-broadcast-sample

[eaphone]

which platform are you using? you can not run webgl at unity editor with this project now.

[flankechen]

@eaphone hi, I am runing this on standalone linux platform setup. I know it's no webgl. the stange thing is, some desektop ubuntu18.04 runs well with this sample. this server environment fails. I notice other guys report server environment runs but not the docker environment as well

[kannan-xiao4]

@flankechen I'm having a problem that looks the same in my environment, so I'll check. Just in case, is it also happening in the WebRTC sample?
