See http://goo.gl/ll2FvQ for common issues.

Issue Description:
I am trying to automate a WebRTC (Real Time Communication) Application 
,designed on HTML5 and it runs on Chrome browser .
In this application i need to access and capture the input from the Microphone 
or Camera from web application.
When i click on capture button, chrome is showing info bar(a kind of popup 
alert) with “allow” and “deny” options., Since this info bar i cannot 
handle with Selenium web driver.

After doing some research i came, to know that, If i manually launch chrome 
browser from command line with a switch “--use-fake-ui-for-media-stream” 
chrome is allowing to access the camera without info bar.

Example: C:\Users\user>start chrome --use-fake-ui-for-media-stream

But if i try the same switch web driver script,i am still getting the info bar 
with same "allow" and "deny" options when my script try to enable camera or 
microphone.

how to suppress this info bar as it worked manual chrome browser launch from 
command line? 

Selenium Web Driver Code Snippet:
import java.io.IOException;
import java.net.URL;
import java.util.Arrays;
import org.openqa.selenium.By;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
public class UseChromeSwitch {
public static void main(String[] args) throws IOException {
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(“chrome.switches”,Arrays.asList(“--use-fake-ui-
for-media-stream”));
RemoteWebDriver driver1 = new RemoteWebDriver(new 
URL(“http://127.0.0.1:4444/wd/hub”), capabilities);
driver1.get(“http://www.html5rocks.com/en/tutorials/getusermedia/intro/”);
driver1.findElement(By.id(“capture-button”)).click();
}
}

Note: Before running above code you need to run the from command line:
java -Dwebdriver.chrome.driver=”C:\chromedriver.exe” -jar 
“C:\selenium-server-standalone-2.41.0.jar”

(Note: Using very latest Chrome Driver)
Note: Please try this on laptop which has built-in camera otherwise you cannot 
access the camera.

Please provide chrome switch through ChromeOptions and it is working fine
Chrome:41, ChromeDriver:2.14

Please find below code:
ChromeOptions options = new ChromeOptions();
options.addArguments("--use-fake-ui-for-media-stream");

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

WebDriver driver = new RemoteWebDriver(new 
URL("http://localhost:4444/wd/hub"),capabilities);
driver.get("http://www.html5rocks.com/en/tutorials/getusermedia/intro");
driver.findElement(By.id("capture-button")).click()
