DetectRTC.jsDetectRTC | Is WebRTC Supported In Your Browser?
Live Demo: https://www.webrtc-experiment.com/DetectRTC/
if (DetectRTC.isWebRTCSupported === false) {
alert('Please use Chrome or Firefox.');
}
if (DetectRTC.hasWebcam === false) {
alert('Please install an external webcam device.');
}
if (DetectRTC.hasMicrophone === false) {
alert('Please install an external microphone device.');
}
if (DetectRTC.hasSpeakers === false && (DetectRTC.browser.name === 'Chrome' || DetectRTC.browser.name === 'Edge')) {
alert('Oops, your system can not play audios.');
}What is this?
A tiny JavaScript library that can be used to detect WebRTC features e.g. system having speakers, microphone or webcam, screen capturing is supported, number of audio/video devices etc.
Free?
It is MIT Licenced, which means that you can use it in any commercial/non-commercial product, free of cost.
Tests?
Releases?

DetectRTC is supporting version property since 1.4.1.
if(DetectRTC.version === '1.4.1') {
alert('We are using DetectRTC version 1.4.1');
}Why load method?
If you're not detecting audio/video input/output devices then you can skip this method.
DetectRTC.load simply makes sure that all devices are captured and valid result is set for relevant properties.
How to fix devices' labels?
You need to check for device.isCustomLabel boolean. If this boolean is true then assume that DetectRTC given a custom label to the device.
You must getUserMedia request whenever you find isCustomLabel===true. getUserMedia request will return valid device labels.
if (DetectRTC.MediaDevices[0] && DetectRTC.MediaDevices[0].isCustomLabel) {
// it seems that we did not make getUserMedia request yet
navigator.mediaDevices.getUserMedia({
audio: true,
video: true
}).then(function(stream) {
var video;
try {
video = document.createElement('video');
video.muted = true;
video.src = URL.createObjectURL(stream);
video.style.display = 'none';
(document.body || document.documentElement).appendChild(vide);
} catch (e) {}
DetectRTC.load(function() {
DetectRTC.videoInputDevices.forEach(function(device, idx) {
// ------------------------------
// now you get valid label here
console.log(device.label);
// ------------------------------
});
// release camera
stream.getTracks().forEach(function(track) {
track.stop();
});
if (video && video.parentNode) {
video.parentNode.removeChild(video);
}
});
});
} else {
DetectRTC.videoInputDevices.forEach(function(device, idx) {
console.log(device.label);
});
}How to select specific camera?
Demo: https://jsfiddle.net/cf90az9q/
<script src="https://www.webrtc-experiment.com/DetectRTC/CheckDeviceSupport.js"></script>
<script>
function selectSecondaryCamera() {
checkDeviceSupport(function() {
var secondDevice = videoInputDevices[1];
if(!secondDevice) return alert('Secondary webcam is NOT available.');
var videoConstraints = {
deviceId: secondDevice.deviceId
};
if(!!navigator.webkitGetUserMedia) {
videoConstraints = {
mandatory: {},
optional: [{
sourceId: secondDevice.deviceId
}]
}
}
navigator.getUserMedia = navigator.mozGetUserMedia || navigator.webkitGetUserMedia;
navigator.getUserMedia({ video: videoConstraints }, function(stream) {
//
}, function(error) {
alert(JSON.stringify(error));
});
});
}
