How can I pass a fake media stream to firefox from command line?

问题

I am developing a java/selenium based application and need to pass media i.e. audio and/or video files to the browser.

I have been able to successfully do this in Chrome using the below code snippet:

DesiredCapabilities capabilities = DesiredCapabilities.chrome(); 
ChromeOptions options = new ChromeOptions();
options.addArguments("--allow-file-access-from-files",
            "--use-fake-ui-for-media-stream",
            "--allow-file-access",
            "--use-file-for-fake-audio-capture=D:\\PATH\\TO\\WAV\\xxx.wav",
            "--use-fake-device-for-media-stream");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);

Are there similar options available in Firefox 33.1 to achieve the same capability?

If not, how can this be done?

回答1:

Firefox has only these capabilities, browserName, browserVersion, platformName, acceptInsecureCerts, pageLoadStrategy, proxy, setWindowRect, timeouts, unhandledPromptBehavior

But as a option, there is one as in a below code,
