Safaridriver not support select audio/ video device

Question

Problem In Mac OS, when use Safaridriver open a Safari browser for WebRTC samples, the audio input source only display Mock device (audio: Mock audio device 1/ Mock audio device 2 , video: Mock video device 1/ Mock video device 2) but not display Mac OS physical or Virtual audio/video device . Safaridriver control Safari browser actually result : enter image description here

Except result : enter image description here

Research

1. Manually open Safari browser , user can set Use Mock Capture Devices (Safari browser->Develop->WebRTC→Use Mock Capture Devices). enter image description here

2. If enable Use Mock Capture Devices , thin-client meeting or WebRTC samples can reproduce above problem .Debug WebRTC samples source code , navigator.mediaDevices.getUserMedia get device return Mock device . enter image description here

3. From safaridriver readMe, no configure can set Use Mock Capture Devices , because WebDrier test not support live media capture "For security reasons, Safari does not permit live media capture during a WebDriver test session. Instead, mock capture devices and streams with well-known contents are provided for testing purposes. " (In Mac OS , cd/Library/Apple/System/Library/CoreServices/SafariSupport.bundle/Contents/MacOS , man safaridriver)

4. From safaridriver debug log, safaridriver not provide any configure for SafaridirverLog

5. From selenium-safari-driver-4.1.3 (The latest release), no configure for Use Mock Capture Devices

Reproduce demo SafariDriverDebug.java

import org.openqa.selenium.safari.SafariDriver;
import org.openqa.selenium.safari.SafariOptions;
 
import org.openqa.selenium.WebDriver;
public class SafariDriverDebug {
public static void main(String[] args) throws  Exception{
    SafariOptions options = new SafariOptions();
    options.setCapability("safari:diagnose", "true");
    //options.setCapability("safari:automaticProfiling", "true");
    WebDriver driver = new SafariDriver(options);
    // Launch Website
    driver.navigate().to("https://webrtc.github.io/samples/src/content/devices/input-output/");
    Thread.sleep(3000);
    // Close the Browser
    driver.close();
    }
}
