In this WebAR example, it always turn on the front device camera when this AR webpage opened on google chrome browser in my android phone. However I want to set the back device camera as the default camera. How should I do?

Pretty sure changing the default camera is done in-browser, not in your code.

Ah, although it looks like it may be different on mobile. Folks here seemed to be having the same issue as you: https://groups.google.com/forum/#!msg/discuss-webrtc/i07T1X_DY94/qW8j9fNSpz4J

If you scroll to the bottom, you'll see posts from 2016 on how to handle it.

According to the forum, this is a possible solution. The issue is that it works for a video tag, but the video in the library is inserted inside a canvas.

Do you know how to solve this issue without adding code to the library?

I have tried the solution in this closed issue, but it is still not working on Galaxy S6 with Android 6.0.1

@DavideCapitola see #53 and https://github.com/sdwolf/ar-experiment for a working solution.

I was able to select the camera on mobile using facingMode option:

        The configuration object supports the following attributes:

            {
                onSuccess : function(video),
                onError : function(error),

                width : number | {min: number, max: number},
                height : number | {min: number, max: number},

                facingMode : 'environment' | 'user' | 'left' | 'right' | { exact: 'environment' | ... }
                deviceId : string | {exact: 'string'}
            }
