OpenTok Python SDK
If you are updating from a previous version of this SDK, see "Important changes since v2.2.0" below.
Installation using Pip (recommended):
Pip helps manage dependencies for Python projects using the PyPI index. Find more info here: http://www.pip-installer.org/en/latest/
Add the opentok package as a dependency in your project. The most common way is to add it to your requirements.txt file:
Next, install the dependencies:
$ pip install -r requirements.txt
Import the package at the top of any file where you will use it. At the very least you will need the OpenTok class. Then initialize an OpenTok instance with your own API Key and API Secret.
from opentok import OpenTok opentok = OpenTok(api_key, api_secret)
The create an OpenTok Session, use the opentok.create_session() method. There are two optional keyword parameters for this method: location which can be set to a string containing an IP address, and media_mode which is a String (defined by the MediaModes class). This method returns a Session object. Its session_id attribute is useful when saving to a persistent store (such as a database).
# Create a session that attempts to send streams directly between clients (falling back # to use the OpenTok TURN server to relay streams if the clients cannot connect): session = opentok.create_session() from opentok import MediaModes # A session that uses the OpenTok Media Router: session = opentok.create_session(media_mode=MediaModes.routed) # A session with a location hint session = opentok.create_session(location=u'22.214.171.124') # Store this session ID in the database session_id = session.session_id
Once a Session is created, you can start generating Tokens for clients to use when connecting to it. You can generate a token either by calling the opentok.generate_token(session_id) method or by calling the session.generate_token() method on a Session instance after creating it. There is a set of optional keyword parameters: role, expire_time, and data.
# Generate a Token from just a session_id (fetched from a database) token = opentok.generate_token(session_id) # Generate a Token by calling the method on the Session (returned from create_session) token = session.generate_token() from opentok import Roles # Set some options in a token token = session.generate_token(role=Roles.moderator, expire_time=int(time.time()) + 10, data=u'name=Johnny')
Working with Archives
You can start the recording of an OpenTok Session using the opentok.start_archive(session_id) method. This method takes an optional keyword argument name to assign a name to the archive. This method will return an Archive instance. Note that you can only start an Archive on a Session that has clients connection.
archive = opentok.start_archive(session_id, name=u'Important Presentation') # Store this archive_id in the database archive_id = archive.id
You can stop the recording of a started Archive using the opentok.stop_archive(archive_id) method. You can also do this using the archive.stop() method of an Archive instance.
# Stop an Archive from an archive_id (fetched from database) opentok.stop_archive(archive_id) # Stop an Archive from an instance (returned from opentok.start_archive) archive.stop()
To get an Archive instance (and all the information about it) from an archive ID, use the opentok.get_archive(archive_id) method.
archive = opentok.get_archive(archive_id)
To delete an Archive, you can call the opentok.delete_archive(archive_id) method or the archive.delete() method of an Archive instance.
# Delete an Archive from an archive ID (fetched from database) opentok.delete_archive(archive_id) # Delete an Archive from an Archive instance (returned from opentok.start_archive or opentok.get_archive) archive.delete()
You can also get a list of all the Archives you've created (up to 1000) with your API Key. This is done using the opentok.list_archives() method. There are two optional keyword parameters: count and offset; they can help you paginate through the results. This method returns an instance of the ArchiveList class.
archive_list = opentok.list_archive() # Get a specific Archive from the list archive = archive_list.items[i] # Iterate over items for archive in iter(archive_list): pass # Get the total number of Archives for this API Key total = archive_list.total
There are two sample applications included in this repository. To get going as fast as possible, clone the whole repository and follow the Walkthroughs:
Reference documentation is available at <http://www.tokbox.com/opentok/libraries/server/python/reference/index.html> and in the docs directory of the SDK.
You need an OpenTok API key and API secret, which you can obtain at https://dashboard.tokbox.com/
The OpenTok Python SDK requires Python 2.6, 2.7, 3.2, 3.3, or 3.4
See the Releases page for details about each release.
Important changes since v2.2
Changes in v2.2.1:
The default setting for the create_session() method is to create a session with the media mode set to relayed. In previous versions of the SDK, the default setting was to use the OpenTok Media Router (media mode set to routed). In a relayed session, clients will attempt to send streams directly between each other (peer-to-peer); if clients cannot connect due to firewall restrictions, the session uses the OpenTok TURN server to relay audio-video streams.
Changes in v2.2.0:
This version of the SDK includes support for working with OpenTok 2.0 archives. (This API does not work with OpenTok 1.0 archives.)
The OpenTok.create_session() method now includes a media_mode parameter, instead of a p2p parameter.
For details, see the reference documentation at <http://www.tokbox.com/opentok/libraries/server/python/reference/index.html>.
