ONVIF Client Implementation in Python base wsdl ver10/20, support hevc(h.265)

Dependencies

zeep <http://docs.python-zeep.org>_ >= 3.0.0

Install python-onvif2-zeep

python-onvif-zeep ,see https://github.com/FalkTannhaeuser/python-onvif-zeep)

From Source

You should clone this repository and run setup.py::

cd python-onvif2-zeep && python setup.py install

Alternatively, you can run::

pip install --upgrade onvif2_zeep

Getting Started

Initialize an ONVIFCamera instance


::

    from onvif2 import ONVIFCamera
    from zeep.transports import Transport
    mycam = ONVIFCamera('192.168.0.2', 80, 'user', 'passwd', wsdl_dir='/home/onvif2/wsdl')

Now, an ONVIFCamera instance is available. By default, a devicemgmt service is also available if everything is OK.

So, all operations defined in the WSDL document::

/home/onvif2/ver10/device/wsdl/devicemgmt.wsdl

download the wsdl folder,and put to the /home/onvif2

are available.

Get media2 from your camera

::

media2_service = self.mycam.create_media2_service()

## get the streamUri
profiles = media2_service.GetProfiles()
    for profile in profiles:
        o = self.media2_service.create_type('GetStreamUri')
        o.ProfileToken = profile.token
        o.Protocol = 'RTSP'
        uri = self.media2_service.GetStreamUri(o)

        dic = {'token': profile.token,
               'rtsp': uri}
        print(dic)

## get video info , 'h265' or 'h264', 'width' 'height' 'gop' ....
configurations = media2_service.GetVideoEncoderConfigurations()

    for configuration in configurations:
        if configuration['Encoding'].lower() == 'h264' or configuration['Encoding'].lower() == 'h265':
            width = configuration['Resolution']['Width']
            height = configuration['Resolution']['Height']
            dic = {'token': configuration['token'],
                   'encoding': configuration['Encoding'],
                   'ratio': "{}*{}".format(width, height),
                   'fps': configuration['RateControl']['FrameRateLimit'],
                   'bitrate': configuration['RateControl']['BitrateLimit'],
                   'gop': configuration['GovLength'],
                   'profile': configuration['Profile'],
                   'quality': configuration['Quality']}
        else:
            dic = {'token': configuration['Name'], 'encoding': configuration['Encoding']}

        print(dic)

Get information from your camera

::

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

# Get system date and time
dt = mycam.devicemgmt.GetSystemDateAndTime()
tz = dt.TimeZone
year = dt.UTCDateTime.Date.Year
hour = dt.UTCDateTime.Time.Hour

Configure (Control) your camera


To configure your camera, there are two ways to pass parameters to service methods.

**Dict**

This is the simpler way::

    params = {'Name': 'NewHostName'}
    device_service.SetHostname(params)

**Type Instance**

This is the recommended way. Type instance will raise an
exception if you set an invalid (or non-existent) parameter.

::

    params = mycam.devicemgmt.create_type('SetHostname')
    params.Hostname = 'NewHostName'
    mycam.devicemgmt.SetHostname(params)

    time_params = mycam.devicemgmt.create_type('SetSystemDateAndTime')
    time_params.DateTimeType = 'Manual'
    time_params.DaylightSavings = True
    time_params.TimeZone.TZ = 'CST-8:00:00'
    time_params.UTCDateTime.Date.Year = 2014
    time_params.UTCDateTime.Date.Month = 12
    time_params.UTCDateTime.Date.Day = 3
    time_params.UTCDateTime.Time.Hour = 9
    time_params.UTCDateTime.Time.Minute = 36
    time_params.UTCDateTime.Time.Second = 11
    mycam.devicemgmt.SetSystemDateAndTime(time_params)

Use events
mycam = ONVIFCamera('192.168.1.10', 8899, 'admin', 'admin') #, no_cache=True)
event_service = mycam.create_events_service()
print(event_service.GetEventProperties())

pullpoint = mycam.create_pullpoint_service()
req = pullpoint.create_type('PullMessages')
req.MessageLimit=100
print(pullpoint.PullMessages({"Timeout":timedelta(seconds=2),"MessageLimit":10}))

Use other services

ONVIF protocol has defined many services.
You can find all the services and operations `here <http://www.onvif.org/onvif/ver20/util/operationIndex.html>`_.
ONVIFCamera has support methods to create new services::

    # Create ptz service
    ptz_service = mycam.create_ptz_service()
    # Get ptz configuration
    mycam.ptz.GetConfiguration()
    # Another way
    # ptz_service.GetConfiguration()

Or create an unofficial service::

    xaddr = 'http://192.168.0.3:8888/onvif/yourservice'
    yourservice = mycam.create_onvif_service('service.wsdl', xaddr, 'yourservice')
    yourservice.SomeOperation()
    # Another way
    # mycam.yourservice.SomeOperation()

ONVIF CLI
---------
python-onvif also provides a command line interactive interface: onvif-cli.
onvif-cli is installed automatically.

Single command example

::

$ onvif-cli devicemgmt GetHostname --user 'admin' --password '12345' --host '192.168.0.112' --port 80
True: {'FromDHCP': True, 'Name': hision}
$ onvif-cli devicemgmt SetHostname "{'Name': 'NewerHostname'}" --user 'admin' --password '12345' --host '192.168.0.112' --port 80
True: {}

Interactive mode


::

    $ onvif-cli -u 'admin' -a '12345' --host '192.168.0.112' --port 80 --wsdl /etc/onvif/wsdl/
    ONVIF >>> cmd
    analytics   devicemgmt  events      imaging     media       ptz
    ONVIF >>> cmd devicemgmt GetWsdlUrl
    True: http://www.onvif.org/
    ONVIF >>> cmd devicemgmt SetHostname {'Name': 'NewHostname'}
    ONVIF >>> cmd devicemgmt GetHostname
    True: {'Name': 'NewHostName'}
    ONVIF >>> cmd devicemgmt SomeOperation
    False: No Operation: SomeOperation

NOTE: Tab completion is supported for interactive mode.

Batch mode

::

$ vim batchcmds
$ cat batchcmds
cmd devicemgmt GetWsdlUrl
cmd devicemgmt SetHostname {'Name': 'NewHostname', 'FromDHCP': True}
cmd devicemgmt GetHostname
$ onvif-cli --host 192.168.0.112 -u admin -a 12345 -w /etc/onvif/wsdl/ < batchcmds
ONVIF >>> True: http://www.onvif.org/
ONVIF >>> True: {}
ONVIF >>> True: {'FromDHCP': False, 'Name': NewHostname}
