I have built an electron app that uses the camera, via getUserMedia. When I build the app in the development environment (with the electron cmd), the Ecamm Live virtual camera works fine. However, when I build for production with electron-builder (with hardened runtime and notarization), Ecamm Live no longer shows up in the production app. I am building and testing in macOS.

I am using navigator.mediaDevices.enumerateDevices() to list the devices. Other physical cameras work in the production app, just not virtual cameras such as Ecamm Live.

Any idea what's going on? I have upgraded the Electron version to 9.1.0, as I had read that there were some changes in Chrome >80 that might affect this, but that didn't help. FWIW, the camera appears fine in my Chrome app.

Figured it out, with some clues from this question.

To get virtual cameras to work in a notarized, hardened runtime app (I believe this also applies to fully native mac apps), you need to disable library validation with the com.apple.security.cs.disable-library-validation entitlement.

Once I added that entitlement and rebuilt the electron app, virtual cameras worked as expected.
