Error with GetSreamUri Function: No namespace defined for 'ter'

See original GitHub issue

Hello Guys I get this error when I try to run the function GetStreamUri:

  File "/usr/local/lib/python3.5/dist-packages/onvif_zeep-0.2.12-py3.5.egg/onvif/", line 23, in wrapped
    return func(*args, **kwargs)

    return call(params, callback)
  File "/usr/local/lib/python3.5/dist-packages/onvif_zeep-0.2.12-py3.5.egg/onvif/", line 140, in call
    ret = func(**params)

    "No namespace defined for %r (%r)" % (prefix, value))
zeep.exceptions.XMLParseError: No namespace defined for 'ter' ('ter:InvalidArgVal')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "", line 32, in <module>
  File "/usr/local/lib/python3.5/dist-packages/onvif_zeep-0.2.12-py3.5.egg/onvif/", line 26, in wrapped
    raise ONVIFError(err)
onvif.exceptions.ONVIFError: Unknown error: No namespace defined for 'ter' ('ter:InvalidArgVal')

Here is the funtion I am running:

from onvif import ONVIFCamera, ONVIFService

 mycam = ONVIFCamera('', 80, 'admin', '12345')
 media_service = mycam.create_media_service()
 profiles = media_service.GetProfiles()
 token = profiles[0].token         // using attribute '_token' returns and error so I am using atribute 'token'

obj = media_service.create_type('GetStreamUri')
obj.ProfileToken = token
obj.StreamSetup = {'Stream': 'RTP-Unicast', 'Transport': {'Protocol': 'RTSP'}}

The error occurs on the funtion: ##obj = media_service.create_type(‘GetStreamUri’)

I have tried installing using pip3 and I have also tried installing from the github repo. I have also checkout different versions of the github repo, but all give the same error.

Any help will be appreciated, thanks, @FalkTannhaeuser @sinchb @iomihai @mpromonet @eLvErDe

I write a simple base on example/ and python-onvif-zeep/issues/4, it work nice with HiKvision camera, as follow:

import zeep
from onvif import ONVIFCamera, ONVIFService

def zeep_pythonvalue(self, xmlvalue):
    return xmlvalue

zeep.xsd.simple.AnySimpleType.pythonvalue = zeep_pythonvalue

def media_profile_configuration():
    A media profile consists of configuration entities such as video/audio
    source configuration, video/audio encoder configuration,
    or PTZ configuration. This use case describes how to change one
    configuration entity which has been already added to the media profile.

    # Create the media service
    mycam = ONVIFCamera('', 80, 'admin', 'xxxxxx', 'E://python-onvif-zeep/wsdl/')
    media_service = mycam.create_media_service()

    token = None
    profiles = media_service.GetProfiles()
    print("dump profiles and find first profile token")
    for prof in profiles:
        if not token:
            token = prof["token"]

    # Use the first profile and Profiles have at least one
    # token = profiles[0]._token
    token = "Profile_1"

    # Get all video encoder configurations
    configurations_list = media_service.GetVideoEncoderConfigurations()
    print("dump configuration list")
    for config in configurations_list:

    obj = media_service.create_type('GetStreamUri')
    obj.ProfileToken = token
    obj.StreamSetup = {'Stream': 'RTP-Unicast', 'Transport': {'Protocol': 'RTSP'}}
    print("dump stream uri")

I know this is old, but if anyone faces this issue, try to replace the code in - ONVIFService - __init__ From

       self.create_type = lambda x: self.zeep_client.get_element('ns0:' + x)()


        namespace = binding_name[binding_name.find("{") + 1 : binding_name.find("}")]
        available_ns = self.zeep_client.namespaces
        active_ns = (
            or "ns0"
        self.create_type = lambda x: self.zeep_client.get_element(active_ns + ":" + x)()
