How to download video from dailymotion?

I have to download videos from dailymotion. I searhed for java libraries and apis but I couldn't find anything useful. I learnt selenium at last and tried to use websites for video downloading manually like savefrom etc. Dailymotion videos can't be downloaded from any website right now. Is there a common way to video download form any website. If there is not, can you help me with dailymotion, spesifically?

Solution

I've used Selenium to download videos. It opens savefrom.net in chrome browser, paste a link that is taken from a dailymotion video and just click download button. You can download videos with this way from any website.

    System.setProperty("webdriver.chrome.driver", "projectPath/Dailymotion/chromedriver.exe");

    WebDriver driver = new ChromeDriver();
    driver.get("https://en.savefrom.net");

    WebElement textField = driver.findElement(By.id("sf_url"));
    textField.sendKeys("https://www.dailymotion.com/video/x737y37");

    WebElement button = driver.findElement(By.id("sf_submit"));
    button.click();

    try {
        TimeUnit.SECONDS.sleep(15);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    driver.findElement(By.linkText("Download")).click();
