在python中获取海康威视网络摄像机的框架

我拥有下一台海康威视IP摄像机http://www.hikvision.com/es/Products_accessries_161_i11969.html我在本地网络中配置了它，并且我已经连接到浏览器，并且我可以看到相机正常工作。我已经在不同的帖子中搜索这样的相机，但我不能这样做。在这里，我把我用来尝试它的代码和响应。我想获得一个框架并将其保存在我的去库存中以进行处理。在python中获取海康威视网络摄像机的框架

使用此代码我无法获得一个框架。

其他选项：

camera = requests.get('http://192.168.1.64', auth=('admin', contrasenia), stream=True)

bytes += bytes()

其他：

其他：

此代码是从其他帖子与类似的问题，但我不能用它来获得我的目标。我能做什么？

我可以使用以下命令下载图片： “Wget -r -P ./ -A jpg，jpeg，*'http：// admin：[email protected]/Streaming/channels/1/picture' “ 但我需要在python中实时获取此图像，并且无法连接到我指出的网址。我怎么能这样做？我曾尝试使用urllib库，但错误是它不是非数字端口，此外，urllib3也不可能。有任何想法吗？ –

您是否找到解决方案？我也有同样的问题。 – Leopoldo

我在我的电脑有一个问题，opencv版本有问题。现在，我有opencv 3.2，我可以做下一行：

cv2.VideoCapture("rstp://admin:[email protected]/doc/page/previw.asp")

我可以采取帧。
