Since @javigzz's answer did not work for me, here is a twig extension that works with the latest version of sonata_media:

namespace Socialbit\SonataMediaTwigExtensionBundle\Twig;

use Sonata\CoreBundle\Model\ManagerInterface;
use Symfony\Component\DependencyInjection\Container;

Class:
/**
 * Description of MediaPathExtension
 *
 * @author thomas.kekeisen
 */
class MediaPathExtension extends \Twig_Extension
{
    /**
     *
     * @var type Container
     */
    protected $container;

    /**
     *
     * @var type ManagerInterface
     */
    protected $mediaManager;

    public function __construct(Container $container, $mediaManager)
    {
        $this->container = $container;
        $this->mediaManager = $mediaManager;
    }

    public function getFunctions()
    {
        return array
        (
            'media_public_url' => new \Twig_Function_Method($this, 'getMediaPublicUrl')
        );
    }

    /**
     * @param mixed $media
     *
     * @return null|\Sonata\MediaBundle\Model\MediaInterface
     */
    private function getMedia($media)
    {
        $media = $this->mediaManager->findOneBy(array(
            'id' => $media
        ));

        return $media;
    }

    public function getMediaPublicUrl($media, $format)
    {
        $media = $this->getMedia($media);

        $provider = $this->container->get($media->getProviderName());

        return $provider->generatePublicUrl($media, $format);
    }

    public function getName()
    {
        return 'SocialbitSonataMediaTwigExtensionBundleMediaPathExtension';
    }
}

services.yml:

services:
    socialbit.sonatamediatwigextensionbundle.mediapathextension:
        class: Socialbit\SonataMediaTwigExtensionBundle\Twig\MediaPathExtension
        public: false
        arguments:
            - @service_container
            - @sonata.media.manager.media
        tags:
            - { name: twig.extension }

The usage will be the same:

{% set img_url = media_public_url(media, 'reference') %}
{{ dump(img_url) }}
