Chrome MediaStreamTrack.getSources () returns sources with an empty label

Question

As an example, I used simpl.info . In their example, I see "TOSHIBA Web Camera - HD (13d3: 5606)" in the "Video Source" section. Therefore, they can get the label property for sources. I can easily get the sources, but the label is empty:

SourceInfo {facing: "", label: "", kind: "video", id: "0c2c5a2bf359a3ced6d7d39efe2f40477f50d5627df618a6f1998b5142437b27"}

Here is my code:

$(document).ready(function ()
{
    if (navigator.getUserMedia)
    {
        if (typeof MediaStreamTrack.getSources !== 'undefined')
        {
            MediaStreamTrack.getSources(gotSources);
        }
    }
});

function gotSources(sourceInfos)
{
    for (var i = 0; i < sourceInfos.length; i++)
    {
        var sourceInfo = sourceInfos[i];

        if (sourceInfo.kind == 'video')
        {
            console.log(sourceInfo);
        }
    }
}
