我做了一切来用 python 操作 ptz

我不确定是否专注于/专注。Onvif主页，似乎显示为焦点移动。

我不知道要获取和编辑什么值，所以我会上传它。

而且即使在调整光圈（光圈）值时，降低该值也可以，但是如果您这样做+，则该值不会很好地改变

在这种情况下，我认为

ptz = mycam.create_imaging_service()

如果通过 ptz.GetOptions() 查看选项，Iris 值为 0（Max）和 -22（Min）。

媒体 = mycam.create_media_service()

media_profile = media.GetVideoSources()[0]

在这里，相机的图像设置是通过 GetVideoSources 加载的。从这个值，在 Imaging.Exposure

有当前光圈值的Iris，Iris最大值的MaxIris，最小值的MinIris。

如果当前光圈值为 -5，则 MinIris 取 -22，但 MaxIris 带来当前光圈值 -5。

即使我每次加载它时都带着改变的值，它似乎也不会改变，但如果你知道如何修复它，请。
