How to restart an image in Qt5 from a separate thread?

Question

Python

class ImageStream(QObject):
        image = pyqtSignal(bytes)
        
        def __init__(self):
            super().__init__()

        def run(self):
            response = requests.get('http://192.168.122.1:8080/liveview/liveviewstream', stream=True)
            for line in response.iter_content(chunk_size=1024*1024):
                if line.find(b'\xff\xd8') != -1 and line.find(b'\xff\xd9') != -1:
                    b_jpeg_s = line.find(b'\xff\xd8')
                    b_jpeg_e = line.find(b'\xff\xd9')
                    self.image.emit(line[b_jpeg_s:b_jpeg_e + 2])

        def flush(self):
            pass


class ExampleApp(QtWidgets.QMainWindow, Qt5_action_cam_main.Ui_MainWindow):

    def __init__(self):
        # Это здесь нужно для доступа к переменным, методам
        # и т.д. в файле design.py
        super().__init__()
        self.setupUi(self)  # Это нужно для инициализации нашего дизайна
        self.start_stream.clicked.connect(self.start)
        self.stop_stream.clicked.connect(self.stop)

    def start(self):
        self.start_stream.setEnabled(False)
        print('Stream Mode Strat')
        response = requests.post('http://192.168.122.1:8080/sony/camera', json={"method": "startLiveview","params": [],"id": 1,"version": "1.0" })
        print(response.content)
        self.pixmap = QPixmap()
        self.thread = QThread()
        self.image_stream = ImageStream()
        self.image_stream.moveToThread(self.thread)
        self.image_stream.image.connect(self.streamThread)
        self.thread.started.connect(self.image_stream.run)
        self.thread.start()

    def streamThread(self, image):
        self.pixmap.loadFromData(image)
        self.label_image.setPixmap(self.pixmap)

    def stop(self):
        response = requests.post('http://192.168.122.1:8080/sony/camera', json={"method": "getEvent","params": [False],"id": 1,"version": "1.0" })
        all_info_cam = json.loads((response.content).decode('utf8').replace("'", '"'))
        if all_info_cam["result"][3]["liveviewStatus"] is True:
            response = requests.post('http://192.168.122.1:8080/sony/camera', json={"method": "stopLiveview","params": [],"id": 1,"version": "1.0" })
            print(response.content)
            print("Stream Paused")
        else:
            response = requests.post('http://192.168.122.1:8080/sony/camera', json={"method": "startLiveview","params": [],"id": 1,"version": "1.0" })
            print(response.content)
            print("Stream Play")

When the stream is stopped and restarted, the image does not update after restarting. How can I make the stream start accepting images again?
