XML-RPC(wp.uploadFile) problem

Hello! I have some promlems with adding new image via xml-rpc(wp.uploadFile).

public function test ()
 	{
 		$image = 'migrates/image.jpg';
 		$result = $this->addImage($image, 2);
 		echo '<pre>';
 		print_r($result);
 	}

public function addImage ($image, $post_id)
	{
		$path = $image;
		$data = file_get_contents($path);
		$base64 = 'data:' . $this->mime_content_type($image). ';base64,' . base64_encode($data);

		$content = array(
            'name' => basename($image),
            'type' => $this->mime_content_type($image),
            'bits' => $base64,
            true,
            //'post_id' => $post_id
        );

        $context = array(0, $this->wpuser, $this->wppassword, $content);

        $xmlcontent = xmlrpc_encode_request('wp.uploadFile', $context, array('encoding'=>'UTF-8','escaping'=>'markup'));
		return $this->makeRequestAPI($xmlcontent);
	}

public function makeRequestAPI($xmlcontent)
 	{
 		$arMessage = array();

		$opt = array(
				'http' => array(
						'method'  => 'POST',
						'headers' => "Content-type: text/xml; charset=utf-8 \r\n".
									 "User-Agent:MyAgent/1.0\r\n".
									 "Content-length:" . strlen($xmlcontent) . "\r\n",
						'content' => "$xmlcontent"
					)
			);
		$context = stream_context_create($opt);	

		$fp = fopen($this->targetURL, 'r', false, $context);
		$result = stream_get_contents($fp);

		$data = xmlrpc_decode($result);
		if (is_array($data) && xmlrpc_is_fault($data)){
			$arMessage[] = "Невозможно получить данные";
			$arMessage[] = "Error Code: " . $data['faultCode'];
			$arMessage[] = "Error Message: " . $data['faultString'];
		}else{
			$arMessage[] = $data;
		}

		return $arMessage;
	}

And my response example to this:

Array
(
    [0] => Array
        (
            [attachment_id] => 84
            [date_created_gmt] => stdClass Object
                (
                    [scalar] => 20160530T12:27:38
                    [xmlrpc_type] => datetime
                    [timestamp] => 1464611258
                )

            [parent] => 0

            [url] => http://wordpress/wp-content/uploads/2016/05/image.jpg
        )

)

But, when I going to admin-media-library my image looks like . I check $base64 before create $context and it was fine(I decode base64 to my image). Can you help me?
