Instead of loading the file using liip data manager, create liip binary object from the uploaded file:

use Liip\ImagineBundle\Model\Binary;

then use the following code:

                // Generate a unique name for the file before saving it
                $fileName = md5(uniqid()) . '.' . $uploadedFile->guessExtension();

                $contents = file_get_contents($uploadedFile);

                $binary = new Binary(
                    $contents,
                    $uploadedFile->getMimeType(),
                    $uploadedFile->guessExtension()
                );

                $container = $this->container;
                $filterManager = $container->get('liip_imagine.filter.manager');    // the filter manager service
                $response = $filterManager->applyFilter($binary, 'my_thumb');

                $thumb = $response->getContent();                               // get the image from the response

                $f = fopen($webRootDir .'/images_dir/' . $fileName, 'w');                                        // create thumbnail file
                fwrite($f, $thumb);                                             // write the thumbnail
                fclose($f);                                                     // close the file
