mediastreamtrack.getsources not supported in firefox, how to do the equivalent

Question

is there an equivalent way to get the list of video devices connected to the PC? I have an external webcam connection in addition to the build-in one.

mediastreamtrack.getsources is working in chrome but firefox reported "TypeError: MediaStreamTrack.getSources is not a function". I am running firefox version 25.0.1

Thanks!

Answer 1

Please use below-mentioned code. It is working properly giving all audio and video devices list.

navigator.mediaDevices.enumerateDevices()
        .then(function (devices) {
            devices.forEach(function (device) {
                var option = document.createElement('option');
                option.value = device.deviceId;
                if (device.kind === 'videoinput') {
                    option.text = device.label || 'camera' + (videoSelect.length + 1);
                    videoSelect.appendChild(option);
                } else if (device.kind == 'audioinput') {
                    option.text = device.label || 'mic' + (audioSelect.length + 1);
                    audioSelect.appendChild(option);
                }
            });
        })
        .catch(function (err) {
            console.log(err.name + ": " + err.message);
        });
