解决方案

WebEngineView 里面的

    onFeaturePermissionRequested: {

        if(feature  == WebEngineView.MediaAudioCapture
                || feature == WebEngineView.MediaAudioVideoCapture
                || feature ==  WebEngineView.MediaVideoCapture){


            grantFeaturePermission(securityOrigin,feature,true)

        } else{
            grantFeaturePermission(securityOrigin,feature,false)

        }
    }
