QWebEngine getDisplayMedia AbortError on macOS 15.3.2 with Qt 6.9

[Maksim Kalinin]

Hi all,

I’m using Qt 6.9 with QWebEngine on macOS 15.3.2. I’m trying to test screen capture using WebRTC via this sample page:

🔗 https://webrtc.github.io/samples/src/content/getusermedia/getdisplaymedia/

I’ve connected the QWebEnginePage::desktopMediaRequested signal as documented, and it does get triggered. However, when I click the “Share Screen” button on the page, I get the following error:

getDisplayMedia error: AbortError

Has anyone managed to get getDisplayMedia() working properly in QWebEngine on macOS? Are there any additional permissions, entitlements, or configurations required for screen capture to work?

Any help would be greatly appreciated!

Thanks!
