pychromecast's Issues

Connection failure

Hi,

I am using pychromecast with Home Assistant. I leave my Chromecast attached to the power permanently so I can use it to wake up my TV remotely via home assistant. Pychromecast connects to my Chromecast perfectly well when I first plug it in but after 12-24 hours uptime I start getting the error below. I can still cast media to the Chromecast from my phone but pychromecast is unable to connect. The only way to work around this error is to power cycle the Chromecast.

Sorry but I am not sure what more I can do to debug this error. I have detailed my set up below:

Pychromecast version 0.7.1 (and git clone from github)
Python version 2.7.9 & 3.4.2
Raspberry Pi v2 (up to date Raspbian Jessie)

i first thought dongle could not be found but that aint the case with second test script.

from __future__ import print_function
import time
import pychromecast
from pychromecast import *


CHROMECAST_HOST = '10.0.0.187'
globals = [0]
bob = pychromecast.get_device_status('10.0.0.187')
print (bob)
cast = pychromecast.Chromecast(CHROMECAST_HOST)

it finds dongle but get second error here.

Add support to launch and control the default receiver app

Chromecast has a default receiver app that is able to play any media on the web that Chrome can decode. Support for this will allow us to launch this app and send media at it.

YouTubeController doesn't display video

Running the exact example given in the description, YouTubeController used to work perfectly.

Now, however, it just hangs on the YouTube splash screen and never actually displays the video.

Any ideas? I captured the data being sent to the chromecast when I cast a video from chrome:

urn:x-cast:com.google.youtube.mdx( 2K{"type":"flingVideo","data":{"videoId":"IPCx9u93XdA","currentTime":22.009}}

So nothing seems to have changed there.

RFE - Support for Multiroom feature of Chromecast Audio

Hi,
it would be great if you support the new Multiroom feature for Chromecast Audio. It was just released. pychromecast is already recognizing something but not yet in a usable way. If I create a group within the Chromecast App an my mobile I see another Chromecast.

pychromecast.get_chromecasts()
[Chromecast(192.168.42.36, zermeiggern, Chromecast Audio, Google Inc., api=1.0), Chromecast(192.168.42.36, zermeiggern, Chromecast Audio, Google Inc., api=1.0), Chromecast(192.168.42.37, furgstalden, Chromecast Audio, Google Inc., api=1.0)]

As you can see it is currently two times the same device. I assume this is something like a master controller for the group. As soon as I remove the group, the second one disappears.

My code:

import pychromecast

    """ Discover chromecasts on the network. """
    try:
        zconf = Zeroconf()
        listener = CastListener()

            return listener.devices
    finally:

Feature request: Kodi (XBMC) service addon?

Would anyone be interested in making a Chromecast Audio (Cast) casting script for Kodi (formerly XBMC) in the form of an service addon for Kodi?

Kodi is an open source media player software has an integrated Python interpreter for running native addons inside Kodi, so it would be very cool if someone would make a Chromecast Audio addon for it based on pychromecast.

The foremost feature that I would like to have it so be able to playback music inside Kodi and have that output (cast) to Chromecast Audio, having Kodi act as a casting sender, however it would also be cool to have Kodi act as a Chromecast Audio receiver as well since you most likly have Kodi connected to your television with speakers anyway.

For my own I think that Kodi (cast) output support would be awesome for multi-room music playback.

PS: To have Kodi act as a Chromecast Audio or Video reciever you could probably take ideas of the existing AirPlay / AirTunes service addon for Kodi.

Implement MDNS

Seems that DIAL is deprecated in favor of MDNS, it might be a good idea to start implementing this too, then.

Not receiving events and always getting the same media status.

It's happening with every video, this is what happens all along the Big buck bunny video from example.py

Please let me know if I can help you further to detect this issue

Media status MediaStatus(current_time=0.583322, content_id=None, content_type=None, duration=0, stream_type=None, idle_reason=None, media_session_id=1, playback_rate=1, player_state=u'PLAYING', supported_media_commands=15, volume_level=1, volume_muted=False, media_customData=None)
Media status MediaStatus(current_time=0.583322, content_id=None, content_type=None, duration=0, stream_type=None, idle_reason=None, media_session_id=1, playback_rate=1, player_state=u'PLAYING', supported_media_commands=15, volume_level=1, volume_muted=False, media_customData=None)

discover_chromecasts doesn't work on machines with multiple network interfaces

Specifically, it only sends the multicast message over the primary interface. Any chromecasts connected to secondary interfaces won't be discovered.

It needs to iterate over all interfaces.

Exception in thread WebSocketClient (most likely raised during interpreter shutdown)

Code:
import time

cast = pychromecast.PyChromecast()
print cast.device
print cast.app
if cast.app_id == pychromecast.APP_ID['HOME']:
print "Chromecast is on the home screen"

app is None for rdio

Was playing around with this today. Noticed that all app related properties are None when the Rdio app is running on the chromecast.

Any idea what's up?

is_idle is always true

Start Netflix
cast.media_controller.is_idle == True no matter whether the video is playing or not

Is there a work-around to discover this?

Publish to PyPI

Now that you've merged the setup.py, please publish the package on PyPI, it's really easy:

python setup.py register
python setup.py sdist upload

You do have to create an account on PyPI and create a .pypirc as shown here: http://peterdowns.com/posts/first-time-with-pypi.html

Zero length field name

Tried to import pychromecast into EventGhost, ran into some trouble though. Managed to add the packages requests and ws4py but still get the following import when I try to import pychromecast:

Traceback (most recent call last):
Python script "36", line 1, in
import pychromecast
File "C:\Program Files (x86)\EventGhost\lib26\site-packages\pychromecast__init__.py", line 9, in

File "C:\Program Files (x86)\EventGhost\lib26\site-packages\pychromecast\upnp.py", line 25, in
'ST: {}\r\n'.format(SSDP_ST) +
ValueError: zero length field name in format

After some googling it seems it is because EventGhost runs an old version of python: 2.6.5 Stackless 3.1b3 060516 (release26-maint, Mar 20 2010, 15:26:51) [MSC v.1500 32 bit (Intel)].

Apparently ever since Python 2.7 the field numbers are not needed anymore, but as this is an earlier version they are required. I tried to fix this myself but have very limited knowledge of Python. Any chance you could make this compatible with an older Python or show me how to fix it myself?

Any help would be much appreciated.

Sleep required between calls

This works:

import pychromecast
import time
cast = pychromecast.get_chromecast()
print cast.device
time.sleep(1)
print cast.status

This doesn't, show status of None:

import pychromecast
import time
cast = pychromecast.get_chromecast()
print cast.device
print cast.status

Send local video to chromecast

Is there anyway using pychromecast to stream a file on the local filesystem to the chromecast using pychromecast? If not, which protocol needs to be implemented to do that? Because the chromecast is capable of doing this.

This would enable my cast command line tool to do:

cast send file:///home/user/videos/holyvideosbatman.mp4

Which would be awesome!

Stream Website or Picture

Hello,
is it also possible to stream a website (html document or link) or a picture (jpeg, png, whatever) to chromecast with this tool?

I would like to create an info screen that is displayed at certain times and triggered from a server.

Is this possible with your tool?

External subtitles?

Is it possible to add an external subtitle track, e.g. from a URL containing an .srt file? If so, how?

ImportError: No module named 'google'

When I run the example.py file with python3.4 example.py I got a strange error:

Traceback (most recent call last):
  File "example.py", line 10, in <module>

    from google.protobuf.internal import enum_type_wrapper
ImportError: No module named 'google'

How can I make this work correctly?

Keep up the good work!

Error handling

It seems rather impossible to handle errors elegantly with the current API. You can't make things like the new volume controls wait_for_response, for example. I took a shot at making a patch to pass along those args, but even if I do and we lose connection to the chromecast, it errors in the background and hangs waiting for the response. I have no way of catching a connection error.

If we can't catch connection errors, we should add some reconnection logic.

Thoughts?

Feature: Start Youtube Video at Specific Time

Feature idea: Allow youtube's start at specific time embed.

For example,
pc.play_youtube_video("jcnMiRCVL18?t=1m27s", cast=cast)
... note the t=1m27s, doesn't seem to work. Unless this method allows for another parameter?

Netflix namespace problem

Great work on this package. I'm trying to get "pause" to work with Netflix and understand I need to add my own namespace. Here's my object:

class MyController(BaseController):
    def __init__(self):
        super(MediaController, self).__init__("urn:x-cast:mdx-netflix-com")
    def receive_message(self, message, data):
        print("Wow, I received this message: {}".format(data))
        return True
    def do_pause(self):
        self.send_message("PAUSE", inc_session_id=True)

Which I instantiate and register. But when I try to use it I get an error:

>>> cast.status
CastStatus(is_active_input=True, is_stand_by=False, volume_level=1.0, volume_muted=False, app_id=u'REMOVED', display_name=u'Netflix', namespaces=[u'urn:x-cast:mdx-netflix-com:service:target:2'], session_id=u'REMOVEDFORTHISPOST', transport_id=u'web-2', status_text='')

    "application.").format(self.namespace))
UnsupportedNamespace: Namespace urn:x-cast:mdx-netflix-com is not supported by runningapplication.

Any idea where I'm going wrong?

Log spamming.

I get these in my logs every 5th second:

I think it would be enough with an INFO level log instead?

Support parsing media metadata

The Cast SDK describes the content that is being played and which data can be extracted.This data should be parsed in the Media Receiver.

I'm probably just missing a line here but I'm not sure what.

I know it must seem odd that I'm making this literally less than 30 minutes after you merged the v2 branch in, but you must understand that I have been walking this earth with bated breath waiting for the moment you pushed these changes. Nonetheless, it no work for me. Am I doin' something wrong? :)

get_chromecast is rather slow.

The get_chromecast method is pretty slow when it performs the initial discovery. I have a stateless script that runs anew every time it is called, but is there something I can serialize and deserialize to make the discovery process quicker? I'll only ever use one Chromecast at a time, so it would be nice if I could save its address and other info to a file and just load that rather than do the complete discovery again.

How can that be done? Can it be added to the docs?

How to Stream a Website?

Hello, I would like to send a website about pythonscript and not Google Chrome. It's about an information screen which is in operation 24/7.
Unfortunately, the Chromecast function of Google Chrome breaks off again and again.
Is this possible?

ConnectionError name errors

There's a simply typo in the pychromecast.__init__.py file, which I'm guessing (without having looked at the git history) arose at some point when ChromecastConnectionError was created.

playlist support for youtube

it would be very useful to add an option to play playlists from youtube, or add multiple songs at the same time. would that be possible?

remotedebug?

According to this article there should be a remotedebug.py that gives access to .crd_open_url() What happened to that? Is there anyway to mimic this functionality?

Events are not sent to listener when pausing video

I have added a listener with media_controller.register_status_listener()

It seems that it is not called when I pause a movie, when I start playing (from scratch, or from pause state) I get an event..

I see it both using netflix, youtube and viaplay (Danish/Swedish streaming provider) and others, so it's not streaming application specific.

Unable to resolve local hostname to IP

Python is not able on all platforms to resolve a local hostname to an IP address.

Move pychromecast.play_youtube_video and pychromecast.play_youtube_playlist

Although it is very convenient to have these functions, i don't think the pychromecast root is the best place to keep them. Maybe these could be moved to a new module like pychromecast.youtube. Then, every time more helper functions like these are created to control apps on the chromecast, a new module can be created to contain them. That way the API will stay nice and tidy, IMHO.

What do you think?

Easily reproducable by sending a URL that is non existing. It would be nice to be able to listen for these in the standard controller.

casting mkv file to chrome

Hi,

I am very pleased to have pychromecast. But I want to report some more feature on pychromecast for it's additional feature.

My scenario is like this.

I have no chrome browser but I can install some module in the server
I have some media file which is various format such as (.mkv, .avi)

Problem.
I want to cast my mkv and avi file with out trascoding.
If it's not possible, I would like to cast during transcording.

Can I do this?

is_active_input problems

I have been trying to debug some issues with Home Assistant and I traced it back down to the is_active_input parameter in the settings. I am not entirely sure what this value is supposed to represent, but I am assuming that it is intended to report if the Chromecast is on the TV's selected input.

For me, it appears that the value reported from the Chromecast is changing at random for systems that I believe to support CEC. Sometimes it works, other times it doesn't. For systems that I know do not support CEC, it appears to not be provided.

This value eventually propagates down to the is_idle property. That value is then used inside of Home Assistant for the Cast's status. When this value is not properly functioning, and an unsupported application (Netflix) is playing, HA will report Off instead of Unknown.

I don't know what anyone else's experience is with this parameter, but, assuming I have the proper understanding of its purpose, it seems buggy for me. I would contend that maybe this parameter should not be considered when calculating is_idle since maybe this parameter should only answer the question of is the Chromecast itself idle. I'm not sure it would be best to have this parameter indicate the status of other devices it is connected to.

Then again, I may not be correctly interpreting the purpose of this value.

unable to get the example.py script to work

When I run the example script, I get the following:

~/pychromecast-master$ python example.py
Traceback (most recent call last):
File "example.py", line 16, in
cast = pychromecast.get_chromecast()

self.host = socket.gethostbyname(host)
TypeError: must be string, not tuple
Exception AttributeError: "'Chromecast' object has no attribute 'socket_client'" in ignored

I'm using Python 2.7.3
~/pychromecast-master$ python --version
Python 2.7.3

Trying to add title errors out with a KeyError

In the play_media function I'm getting an error when trying to pass a title value. It appears to be how it adds the new title to the 'msg' dictionary. I'm not sure what the API is looking for in terms of structure but this is what I believe it should be.

msg['customData']['payload'] = {'title':title}

That may or may not be correct but it's just my 2 cents.

Nice work though, helped me a ton!

ramp returns "None,None" for time while playing

Ramp output while youtube video is playing:

RampSubprotocol(The Best Robin Williams Moments | Mashable, None/None, playing)

Ramp output while paused:

RampSubprotocol(The Best Robin Williams Moments | Mashable, 87.053/None, stopped)

readme shows this working correctly but it seems like I get None/None as ramp output for any playing video.
from readme:

Logging in pychromecast module

The pychromecast module sets the logging level to logging.INFO, globally.
I am currently making a CLI program using pychromecast and everytime i do a play or pause there are these lines of logging I really don't want to see.

Best solution IMO would be to create a singleton logger instance and set the level to logging.INFO on that. That way i can import the logger and set it's level to logging.ERROR for example, so i don't have to look at all the info when i just want to play or pause :)
