```python from selenium import webdriver from selenium.webdriver. chrome .service import Service from selenium.webdriver. chrome .options import Options import json # 启动 Chrome chrome _options = Options() chrome _options.add_argument('--headless') chrome _options.add_argument('--disable-gpu') chrome _options.add_argument('--no-sandbox') chrome _options.add_argument('--disable-dev-shm-usage') chrome _options.add_argument('--remote-debugging-port=9222') chrome _service = Service('/path/to/ chrome driver') chrome _service.start() driver = webdriver.Remote( chrome _options= chrome _options, command_executor= chrome _service.service_url) # 获取视频性能指标 driver.get('https://example.com/video') performance = driver.execute_cdp_cmd('Performance.getMetrics', {}) print(json.dumps(performance, indent=2)) # 关闭 Chrome driver.quit() chrome _service.stop() 这段代码会启动一个无头 Chrome ，然后打开指定的 URL，获取视频的性能指标，并输出为 JSON 格式。你需要将 `/path/to/ chrome driver` 替换为你本地的 Chrome Driver 路径。
