Not able to receive WebRTC calls on Chromedriver 78

[Chaitra Shetty]

After upgrading to Chrome v78.0.3904.70  and ChromeDriver 78.0.3904.70 browser is unable to receive WebRTC calls. This used to work fine with older chromedriver versions.I am using an extension for these WebRTC calls. 

 At first, after upgrading to Chrome v78.0.3904.70  and ChromeDriver 78.0.3904.70, I had error loading the extension. Repackage the extension to CRX3 fixed the issue but now, the incoming WebRTC calls are failing with "WebPhoneVerto: call ended with cause: INCOMPATIBLE_DESTINATION" error. This is not an issue when using Chrome browser. Just an issue when using selenium chromedriver. 

Chrome driver team asked me to post the issue here.

Here is the function where I am setting the chrome profile to launch chrome using chromediver 78:

public ChromeOptions chromeProfile()

   {  

   Path path = FileSystems.getDefault().getPath(FileLocator.BROWSER_DOWNLOAD_DIR.getLocation());

   logger.info("Setting browser download path to "+path.toAbsolutePath().toString());

   

   HashMap<String, Object> chromePreferences = new HashMap<String, Object>();

   chromePreferences.put("profile.default_content_settings.popups", 0);

   chromePreferences.put("download.prompt_for_download", false);

   chromePreferences.put("download.default_directory", path.toAbsolutePath().toString()); 

   if(enableMicrophone)

   chromePreferences.put("hardware.audio_capture_allowed_urls", new String[]{"https://xxx.com", "https://xxx1.com"});

   

   ChromeOptions options = new ChromeOptions();

   if(installExtension)

   options.addExtensions(new File(FileLocator.CHROME_EXTENSION_PATH.getLocation().replace("$STACK",chromeExtensionStack)));

   

   

   if(mobileEmulationDevice != null && !mobileEmulationDevice.isEmpty())

   {

   Map<String, String> mobileEmulation = new HashMap<String, String>();

   mobileEmulation.put("deviceName", mobileEmulationDevice);

   options.setExperimentalOption("mobileEmulation", mobileEmulation);

   }

   options.setExperimentalOption("prefs", chromePreferences);

   if(enableMicrophone)

   {

   options.addArguments("use-fake-ui-for-media-stream");

   options.addArguments("use-fake-device-for-media-stream");

   options.addArguments("allow-file-access-from-files");

   Path audioFilePath = FileSystems.getDefault().getPath(FileLocator.SAMPLE_AUDIO_FILES_DIR.getLocation()+TestContext.TEST_PROPERTIES.get("audioFileName"));

   logger.info("Setting browser download path to "+audioFilePath.toAbsolutePath().toString());

   options.addArguments("use-file-for-fake-audio-capture="+audioFilePath.toAbsolutePath().toString());

   }

   return options;

}

Here is the pluging logs when trying to connect to incoming call:

Can anyone help with this please? Chrome driver team asked me to post the issue here.

have you tried getting a webrtc-internals dump (which might be somewhat tricky in selenium) or added console.log statements to all webrtc-related calls in jquery.FSRTC.js?

Thank You Philipp for helping with this issue!

Fix was to launch chromedriver with following arguments:

path/to/chrome --disable-field-trial-config --disable-features=WebRtcHideLocalIpsWithMdns
