Python ONVIF GotoPreset 设置全局移动速度失败

Question

我正在尝试以定义明确的速度设置名为“Preset001”的点，但我做不到，因为我在控制台上收到以下错误：

My camera's hostname: MYCAM
gotoPreset:
{
    'ProfileToken': 'MainStreamProfileToken',
    'PresetToken': 'Preset001',
    'Speed': 0.1
}

这是执行预设命令的脚本（不设置速度，这个命令完美运行）：

#!/usr/bin/python3

from functions import *


from onvif import ONVIFCamera

mycam = ONVIFCamera('xxx.xxx.xxx.xxx', 8080, 'admin', 'password', '/home/pi/.local/lib/python3.4/site-packages/wsdl/')

# Get Hostname
resp = mycam.devicemgmt.GetHostname()
print("My camera's hostname: " + str(resp.Name))

# Create media service object
media = mycam.create_media_service()

# Get target profile
media_profile = media.GetProfiles()[0]
#print(media_profile)

# Create ptz service object
ptz = mycam.create_ptz_service()

request = ptz.create_type('GotoPreset')

request.ProfileToken = media_profile.token

request.PresetToken = "Preset001"

request.Speed = 0.1

print("gotoPreset:")
print(request)

print(ptz.GotoPreset(request))

我在 RaspberryPi 4 上使用以下“ONVIF Python LIbrary”。

有谁知道如何给我一些建议吗？
我哪里错了？

感谢任何人！

Answer 1

我找到了解决办法。正确的数据传递方式是：

request.Speed = {'PanTilt': {'x': 0.1, 'y': 0.1}, 'Zoom': 0.1} # The camera seems to ignore the PanTilt and Zoom speeds I give it

即使不幸的是我的 ptz 没有达到我告诉他去的速度 cge .. 所以这东西没用 .. : '(

谢谢大家
