pychromecast |Build Status|
===========================

Library for Python 2 and 3 to communicate with the Google Chromecast. It
currently supports: - Auto discovering connected Chromecasts on the
network - Start the default media receiver and play any online media -
Control playback of current playing media - Implement Google Chromecast
api v2 - Communicate with apps via channels - Easily extendable to add
support for unsupported namespaces - Multi-room setups with Audio cast
devices

*PyChromecast 0.6 introduces some backward incompatible changes due to
the migration from DIAL to socket for retrieving the app status.*

Dependencies
------------

PyChromecast depends on the Python packages requests, protobuf and
zeroconf. Make sure you have these dependencies installed using
``pip install -r requirements.txt``

*Some users running Python 2.7 have
`reported <https://github.com/balloob/pychromecast/issues/47#issuecomment-107822162>`__
that they had to upgrade their version of pip using
``pip install --upgrade pip`` before they were able to install the
latest version of the dependencies.*

How to use
----------

.. code:: python

    >> from __future__ import print_function
    >> import time
    >> import pychromecast

    >> pychromecast.get_chromecasts_as_dict().keys()
    ['Dev', 'Living Room', 'Den', 'Bedroom']

    >> cast = pychromecast.get_chromecast(friendly_name="Living Room")
    >> # Wait for cast device to be ready
    >> cast.wait()
    >> print(cast.device)
    DeviceStatus(friendly_name='Living Room', model_name='Chromecast', manufacturer='Google Inc.', api_version=(1, 0), uuid=UUID('df6944da-f016-4cb8-97d0-3da2ccaa380b'), cast_type='cast')

    >> print(cast.status)
    CastStatus(is_active_input=True, is_stand_by=False, volume_level=1.0, volume_muted=False, app_id=u'CC1AD845', display_name=u'Default Media Receiver', namespaces=[u'urn:x-cast:com.google.cast.player.message', u'urn:x-cast:com.google.cast.media'], session_id=u'CCA39713-9A4F-34A6-A8BF-5D97BE7ECA5C', transport_id=u'web-9', status_text='')

    >> mc = cast.media_controller
    >> mc.play_media('http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', 'video/mp4')
    >> print(mc.status)
    MediaStatus(current_time=42.458322, content_id=u'http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4', content_type=u'video/mp4', duration=596.474195, stream_type=u'BUFFERED', idle_reason=None, media_session_id=1, playback_rate=1, player_state=u'PLAYING', supported_media_commands=15, volume_level=1, volume_muted=False)

    >> mc.pause()
    >> time.sleep(5)
    >> mc.play()

Adding support for extra namespaces
-----------------------------------

Each app that runs on the Chromecast supports namespaces. They specify a
JSON-based mini-protocol. This is used to communicate between the
Chromecast and your phone/browser and now Python.

Support for extra namespaces is added by using controllers. To add your
own namespace to a current chromecast instance you will first have to
define your controller. Example of a minimal controller:

.. code:: python

    from pychromecast.controllers import BaseController


    class MyController(BaseController):
        def __init__(self):
            super(MyController, self).__init__(
                "urn:x-cast:my.super.awesome.namespace")

        def receive_message(self, message, data):
            print("Wow, I received this message: {}".format(data))

            return True  # indicate you handled this message

        def request_beer(self):
            self.send_message({'request': 'beer'})

After you have defined your controller you will have to add an instance
to a Chromecast object: ``cast.register_handler(MyController())``. When
a message is received with your namespace it will be routed to your
controller.

For more options see the
`BaseController <https://github.com/balloob/pychromecast/blob/master/pychromecast/controllers/__init__.py>`__.
For an example of a fully implemented controller see the
`MediaController <https://github.com/balloob/pychromecast/blob/master/pychromecast/controllers/media.py>`__.

Exploring existing namespaces
-----------------------------

So you've got PyChromecast running and decided it is time to add support
to your favorite app. No worries, the following instructions will have
you covered in exploring the possibilities.

The following instructions require the use of the `Google Chrome
browser <https://www.google.com/chrome/>`__ and the `Google Cast
plugin <https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd>`__.

-  In Chrome, go to ``chrome://net-internals/#capture``
-  Enable the checkbox 'Include the actual bytes sent/received.'
-  Open a new tab, browse to your favorite application on the web that
   has Chromecast support and start casting.
-  Go back to the tab that is capturing events and click on stop.
-  From the dropdown click on events. This will show you a table with
   events that happened while you were recording.
-  In the filter box enter the text ``Tr@n$p0rt``. This should give one
   SOCKET connection as result: the connection with your Chromecast.
-  Go through the results and collect the JSON that is exchanged.
-  Now write a controller that is able to mimic this behavior :-)

Ignoring CEC Data
-----------------

The Chromecast typically reports whether it is the active input on the
device to which it is connected. This value is stored inside a cast
object in the following property.

::

    cast.status.is_active_input

Some Chromecast users have reported CEC incompatibilities with their
media center devices. These incompatibilities may sometimes cause this
active input value to be reported improperly.

This active input value is typically used to determine if the Chromecast
is idle. PyChromecast is capable of ignoring the active input value when
determining if the Chromecast is idle in the instance that the
Chromecast is returning erroneous values. To ignore this CEC detection
data in PyChromecast, append a `Linux style
wildcard <http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm>`__
formatted string to the IGNORE\_CEC list in PyChromecast like in the
example below.

::

    pychromecast.IGNORE_CEC.append('*')  # Ignore CEC on all devices
    pychromecast.IGNORE_CEC.append('Living Room')  # Ignore CEC on Chromecasts named Living Room

Thanks

I would like to thank `Fred Clift <https://github.com/minektur>`__ for
laying the socket client ground work. Without him it would not have been
possible!
