epipearl
===============================
Python client for [epiphan-pearl][pearl]. It provides a client interface for
epiphan-pearl [http api][pearl-http-api], and some of its web ui configuration
interface, and DCE custom web ui configuration as well.
Current version of Epipearl is tested against _v3.15.3f_ firmware.
This software shoud be considered alpha, therefore likely to change/break in the near future.
install
-------
pip install epipearl
example usage to get and set channels parameters
------------------------------------------------
from epipearl import Epipearl
client = Epipearl( "http://epiphan_pearl_address", "admin", "secret_password" )
# to get the type of stream being published and frame size for channel 1
response = client.get_params( channel='1', params={'publish_type':'', 'framesize':''})
print "publish_type is %s" % response['publish_type']
print "framsize is %s" % response['framesize']
# to start recording on recorder 2
response = client.set_params( channel='m2', params={'rec_enabled': 'on'})
if response:
print "recorder 2 set to start recording"
example usage of web ui methods
------------------------------------------------
Besides the HTTP API calls `get_params()` and `set_params()`, epipearl exposes
some web ui HTML form posts as python calls.
For example, if you need to create a new channel:
# create the client
import requests
from epipearl.errors import SettingConfigError
from epipearl.errors IndiscernibleResponseFromWebUiError
from epipearl import Epipearl
client = Epipearl( "http://epiphan_pearl_address", "admin", "secret_password" )
# to create a channel, give it a name
channel_id = client.create_channel('my new epiphan-pearl channel')
# the returned channel_id is the id to be used to reference this channel
# in all subsequent operations, like setting the rtmp-push settings
try:
client.set_channel_rtmp(
channel_id=channel_id,
rtmp_url='rtmp://some.url.where.to.push.to.eg.akamai',
rtmp_stream='stream_name',
rtmp_usr='user_for_rtmp_eg_akamai_account',
rtmp_pwd='password')
except requests.HTTPError:
print 'error during http request'
except SettingConfigError as e:
print 'device web ui returned error or some settings did not take'
print e.message
except IndiscernibleResponseFromWebUiError:
print 'did not understand response from device web ui'
print e.message
else:
print 'channel({}) rtmp settings done'.format(channel_id)'
For examples on all implemented web ui calls, please check the unit tests in
the tests dir of a local clone. Tests also host examples of json files for
layout inputs and expected json responses from device.
testing
------------------------------------------------
During development, epipearl tests were executed using [pytest][pytest].
To run test from a local git clone:
pip install -r requirements_dev.txt
then, to rul all tests:
py.test tests
You can also run live tests, but these require some environment variables to be
set:
- EPI\_URL: the url to reach the epiphan-pearl web ui
- EPI\_USER: the admin username for epiphan-pearl web ui
- EPI\_PASSWD: the admin password for epiphan-pearl web ui
- EPI\_PUBLISH\_TYPE: 0 or 6 to stop or start rtmp push in epiphan-pearl
Set these in the environment and do
export EPI_URL=http://epiphan_pearl_address
export EPI_USER=admin_user
export EPI_PASSWD=secret_password
export EPI_PUBLISH_TYPE=0 # stop rtmp pushing
py.test tests --runlive
Live tests will connect with actual device and change its settings.
