working with behat 3.0:

use Behat\Mink\Driver\Selenium2Driver;
use Behat\Behat\Hook\Scope\AfterStepScope;

  /**
   * @AfterStep
   */
  public function takeScreenShotAfterFailedStep(afterStepScope $scope)
  {
    if (99 === $scope->getTestResult()->getResultCode()) {
      $driver = $this->getSession()->getDriver();
      if (!($driver instanceof Selenium2Driver)) {
        return;
      }
      file_put_contents('/tmp/test.png', $this->getSession()->getDriver()->getScreenshot());
    }
  }

Note, error code is changed to 99 and the getScreenshot method now returns a binary file, rather than a base64 encoded string.

This is also automatically supported by our behat 3.x extension, amongst other useful features.

There is a dedicated Behat extension (bex/behat-screenshot) for taking screenshots, which can be installed via Composer easily.

It can upload the created image to public image hosting sites and display the URL to it on the console. If you need to upload images to a private server, you can create an image adapter for that easily.
Screenshot taking mode allows to make a combined image of previous steps, which can come handy if one of the previous step is responsible for the failing test case.

Another extension that gives more than just a screenshot with minimal setup! https://github.com/forceedge01/behat-fail-aid
