Returns two input devices: InputDeviceInfo {deviceId: "", kind: "audioinput", label: "", groupId: "", …} InputDeviceInfo {deviceId: "", kind: "videoinput", label: "", groupId: "", …} 2) Call `stream = await navigator.mediaDevices.getUserMedia({video: true})` This fails with the following error: OverconstrainedError {message: "Invalid constraint", constraint: "", name: "OverconstrainedError"} 3) Call `stream = await navigator.mediaDevices.getUserMedia({audio: true})`. The user grants microphone access. The call succeeds and returns a stream. No errors. 4) Call `await navigator.mediaDevices.enumerateDevices()`. Returns ONE input device: InputDeviceInfo {deviceId: "18D5FE168D21164D9C4ED78C74A6A6D2A572513C", kind: "audioinput", label: "MicrophoneBuiltIn", groupId: "FD080DBDD6AA6F6F23AE94E8627078192F0F58C3", …} Expected behavior: If no camera is available, then enumerateDevices() should not return a device of kind "videoinput". 2121514 1 ap 2025-06-03 15:29:29 -0700 Thank you for the report! Does this reproduce with the latest simulator? 2121613 2 milen.yordanov 2025-06-04 00:33:23 -0700 I tested it on the latest iOS 18.5 Simulator, iPhone 16, and the result remains the same. 2122696 3 webkit-bug-importer 2025-06-10 04:36:12 -0700 <rdar://problem/152938326> 2122954 4 youennf 2025-06-11 01:55:25 -0700 Pull request: https://github.com/WebKit/WebKit/pull/46594 2122972 5 ews-feeder 2025-06-11 04:15:20 -0700 Committed 296083@main (22a5e4f2aa67): <https://commits.webkit.org/296083@main> Reviewed commits have been landed.
