Python pyqt5 QWebEngineView不'；自动播放youtube视频

我尝试使用Qwebengineview查看youtube视频列表，但浏览器不会自动播放视频，我使用的是PyQt5 5.13.1 Python 3.6

下面是一个示例代码

from PyQt5.QtCore import QUrl
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineProfile, QWebEnginePage
from PyQt5.QtWidgets import QApplication

if __name__ == '__main__':
    import sys

    app = QApplication(sys.argv)
    webview = QWebEngineView()
    profile = QWebEngineProfile("my_profile", webview)
    profile.defaultProfile().setPersistentCookiesPolicy(QWebEngineProfile.ForcePersistentCookies)
    webpage = QWebEnginePage(profile, webview)
    webview.setPage(webpage)
    webview.load(QUrl("https://www.youtube.com/watch?v=VzIVI2fsRb0"))
    webview.show()
    sys.exit(app.exec_())

我已经使用QWebEngineSettings找到了解决方案，下面是一个完整的工作示例，以防有人需要它

from PyQt5.QtCore import QUrl
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineProfile, QWebEnginePage, QWebEngineSettings
from PyQt5.QtWidgets import QApplication
import time

if __name__ == '__main__':
    import sys

    app = QApplication(sys.argv)
    webview = QWebEngineView()
    profile = QWebEngineProfile("my_profile", webview)
    profile.defaultProfile().setPersistentCookiesPolicy(QWebEngineProfile.ForcePersistentCookies)
    webpage = QWebEnginePage(profile, webview)
    webpage.settings().setAttribute(QWebEngineSettings.PlaybackRequiresUserGesture, False)

    webview.setPage(webpage)
    webview.load(QUrl("https://www.youtube.com/watch?v=aKCNrkERJ3E"))
    webview.show()

    sys.exit(app.exec_())
