Determining which camera is "macro" camera from mobile devices containing multiple cameras using getUserMedia

[Tom Landgrebe]

Good day,

We are trying to find a solution for selecting the correct camera (consistently) using "getUserMedia" when a mobile device has multiple rear cameras. In particular, we would like to select the "macro" camera, or camera for close-up imaging, as opposed to the wide angle camera. Reading the documentation, we cannot find a way to do it, and were hoping there may be a solution?

Currently we use the following routine to select a camera:

navigator.mediaDevices.enumerateDevices()

        .then(function (devices) {

          chosenId = devices.reverse().find(adevice => adevice.label.toLowerCase().includes("back"))?.deviceId

          navigator.mediaDevices.getUserMedia({ video: { facingMode: "environment", deviceId: chosenId, width: { ideal: 640 } }, audio: false })

            .then(function (stream) {

              videoRef.current.srcObject = stream

              const tracks = stream.getTracks()

              update()

            }, function (err: any): void {

              throw err

            })

        })

        .catch(function (err) {

          console.log(err.name + ": " + err.message);

        });

thank you very much

Tom
