Can't switch device camera on android chrome

Unity Engine
,

It’s currently not possible to switch the device camera on chrome for android. Import the attached package to an empty Unity project, and build it for WebGL(no compression).

Proposed solution:
On the webgl.framework.js file:

1- Go to the function addDevice, change its signature to

function addDevice(label, deviceId) {
    label = label ? label : "device #" + MediaDevices.length;
 
    var device = {
        deviceName: label,
        deviceId: deviceId,
        refCount: 0,
        video: null
    };
    MediaDevices.push(device)
}

2- Not much further below, change the following line:
if (device.kind == “videoinput”) addDevice(device.label) to
if (device.kind == “videoinput”) addDevice(device.label, device.deviceId)
_3-_Finally, on the _JS_WebCamVideo_Start function, change the constraints of the getMedia request to:

video: {deviceId: MediaDevices[deviceId].deviceId},
audio: false

This solution only seem to work the first time. After I refresh the browser, I get the error:

To make it work again, you need to clear the cache and then refresh the browser.

But I guess it’s a good starting point.

@jukka_j Hey Jukka, I’d just like to notify that another bug related to device camera on WebGL is live on the issue tracker. I hadn’t made a forum post for this one.

Thanks, that particular one is in my work queue now.
