selenium.webdriver 操作H5视频

方法如下，但是play()和pause()方法在浏览器执行正常，通过webdriver好像有问题。

from selenium import webdriver
from time import sleep

with webdriver.Firefox() as driver:
    driver.get('https://www.17sucai.com/pins/demo-show?id=34262')
    driver.maximize_window()
    driver.implicitly_wait(5)
    driver.switch_to.frame('iframe')
    video = driver.find_element_by_tag_name('video')
    # 获取播放文件地址
    url = driver.execute_script('return arguments[0].currentSrc;', video)
    print(url)
    # 播放视频
    driver.execute_script('arguments[0].play()', video)
    # 保持5S
    sleep(5)
    # 暂停视频
    driver.execute_script('arguments[0].pause()', video)
    sleep(1)
    # 重新加载视频
    driver.execute_script('arguments[0].load()', video)
    sleep(3)
