Bug Description

The situation is quite simple to #392

However, my MacBook is Intel Mac and I can’t find TextureFrame#ChangeNameFrom.

Also, I put Debug.Log in TexutreFrame#GetNativeTexturePtr, but it isn’t called.

Importantly, the error is occurred without scene change.

Sometimes, I can see the web cam screen in the first scene (face detection), and when I change to other scene the error is occurred, but almost all errors occur first scene that means I can’t see the web cam screen at all.

• When I build old version; 0.9.1 and run in unity 2020.3.~~, it works well.

Steps to Reproduce the Bug

1. Run python3.9 build.py build --desktop cpu -vv
2. Start Play Mode and the below error occurs. TimeoutException: Failed to start WebCam

Thank you! Hmm, that’s interesting.

In my case (on Linux Desktop), when it happens, it happens often, and when it doesn’t, it doesn’t happen at all (and now I happen to be unable to reproduce it at all). Can you tell me how much the count will eventually go up in your environment? https://github.com/homuler/MediaPipeUnityPlugin/blob/6efa5e1b75b7c6aa487254ade15fe7cd49fc6842/Assets/MediaPipeUnity/Samples/Common/Scripts/ImageSource/WebCamSource.cs#L264

I encountering this issue too. I am on Mac OS M1.

I got it to go away by setting timeoutFrame to 3000. It seems that 2000 is too low.
