Unity hangs when stopping the app

Software Unity
1

I’m running 8 ZEDX cameras (using 4 zed boxes), with object detection,
when I stop the application, Unity freezes for ~5 min.
any help would be appreciated.

Steps to Reproduce

  1. open scene with 8x zed rigs (mono)
  2. hit play,
  3. after cameras start detecting, stop app

Hi,

At the first use of a AI model, the SDK will download and optimize it, which can take some time.

Can you try to optimize the models manually following this guide ? https://support.stereolabs.com/hc/en-us/articles/9747407795223-How-can-I-optimize-the-ZED-SDK-AI-models-manually-

Best,

Hi Benjamin,

The models actually were optimized manually.
This occurs not during runtime, but when closing the app.
It might have something to do with threads not joining correctly.

However, I will give it a go.

Ok I get it.

You are using multiple cameras, so I suppose you are using our live link sample (GitHub - stereolabs/zed-unity-livelink: ZED Livelink plugin for Unity), is that right?

Actually no, We are using multiple ZED rig prefabs for each camera,
No skeleton tracking

Hi Benjamin,
I have tried the above, did not make a difference unfortunately

Hi, I am actually struggling with the same issue, yet I have the feeling it mostly hangs when closing the app before all cameras have successfully loaded. Any news on this issue?
