Screen Capture API: what screen sharing can verify

Screen Capture allows a user to choose a display surface such as a screen, window or tab for capture in a supported browser.

Why it matters

How this changes a diagnosis

A successful DeviceOK screen-share check proves the browser can request and receive the selected capture stream. It does not prove that Zoom, Teams or OBS is configured to use the same source.

Key points

What to remember

  • The user selects what to share.
  • Browser and operating-system privacy controls can block capture.
  • App-specific capture pipelines can differ from browser capture.
