Hello! 👋

In my project, everything works perfectly inside the Unity Editor — the face landmark detection and the webcam feed are displayed correctly.

But when I build the game (Windows standalone), the webcam does not appear at all.
The UI loads fine, but the RawImage (where the camera feed should be) stays black.

There are no errors or crashes, just no webcam image.

Log

Steps to Reproduce

Open the FaceLandmarker sample or my own blink detection scene.

Run in Editor → webcam works ✅

Build the game → run .exe → webcam not visible ❌

Additional Context

What I Tried

Tested both CPU and GPU delegates — same issue.

Added Application.RequestUserAuthorization(UserAuthorization.WebCam) before Play().

Tried different resolutions and frame rates.

Added debug logs — camera reports “ready”, but no frames appear.

Works fine in Editor, only broken in Build.

Checking in, I have the same problem on linux, in editor everything works fine and the input sources are found but as soon as it's built for linux binaries the media input can't be found anymore.

Never mind, I think I've found the fix,
in unity go to MediaPipeUnity/Samples/Scenes
Then open "AppSettings"
Set Asset Loader Type to Streaming Assets,
Before it was on local which would crash MediaPipe

Could we make this the standard?

AAA, so the folder I was building the project in wasn't written in English, but in Cyrillic. It works now, thanks.

Maybe same as #1284

@CharliVanNood Actually, Streaming Assets is the default setting in this sample project, but the default value of the package (i.e., .tar.gz or .unitypackage) is set to Local.
The reason is that, while we can assume the StreamingAssets folder exists and contains the required model files in the sample project, we cannot make that assumption once the package is imported into another project.
In such cases, if the default value were Streaming Assets, the sample scenes would not work properly on the UnityEditor.

ah okay, thank you
