Tried to use with chromium on the rpi, fails to open chromium when fed the path to it

When no apps are running on the device, HTTP response code 204 is returned on a GET request on the applications ("/apps") uri.

Hello,

I don't get it running. Installing it worked fine, when I start it I get this:

D:\Eigene Dateien\Eigene Downloads\leapcast-master>python leapcast --chrome "C:/Program Files (x86)/
Google/Chrome/Application/chrome.exe" -d
DEBUG:Leapcast:Added ChromeCast app
DEBUG:Leapcast:Added YouTube app
DEBUG:Leapcast:Added PlayMovies app
DEBUG:Leapcast:Added GoogleMusic app
DEBUG:Leapcast:Added GoogleCastSampleApp app
DEBUG:Leapcast:Added GoogleCastPlayer app
DEBUG:Leapcast:Added TicTacToe app
DEBUG:Leapcast:Added Fling app

but nothing happens(not sure if a chrome tab should open or something...)
and I don't get any failure if I change to a wrong chrome path...
And no Chromcast detected in the chrome app, my tablet and smartphone in youtube/play music/play movies

What can I do?

Win7x64 Python2.7.5 Chrome 29 beta

For some weird reason, I am seeing the error below,

$ python3 app.py
File "app.py", line 45
print datagram
^
SyntaxError: invalid syntax

indentation problem? Please help!

When I try to run leapcast it gives me the error
"no module named requests"

Anyone know what to do?

I bisected this to e4a51b3, before it's fine, and after (all the way to a495e96) I get the following error:

On python 2.7.5 I keep getting this error. I tested this on windows Vista en windows 8.

Traceback (most recent call last):

ImportError: No module named twisted.internet

Any suggestions on installing this in Fedora? I have installed the following:

yum install python-virtualenvwrapper python-twisted-web python-devel python-pip
and run python setup.py develop which seemed to work ok. (I do notice that there is no mkvirtualenv command available)

I have included output below of python setup.py develop; leapcast --name x1
and then error produced when trying to cast Google Music from device.

Thanks for any suggestions!

Current version doesn't work due to this hardcoded ip:

The Play Movies app supports both "ramp" and "play-movies" protocols:

http://pastebin.com/vRDQMSEg

I can cast fine for the first time whatever, tab, fullscreen or youtube. But then when I disconnect and reconnect again I begin getting this trace:

Then I am forced to kill chrome and leapcast to make it work again.

My setup is Ubuntu 13.04 and using Chrome 30.0.1599.69 with the latest git clone as todays date (14 october 2013) for the destination host. Source host is OSX Mountain Lion.

Hi,
I'm testing leapcast with Google Music Android app. It seems to work well on first run (I can seek, skip, select new songs, ...) but if I disconnect the app from leapcast and try to reconnect I get error on the app the it looks that leapcast is not able to provide any service.

http://pastebin.com/s40zEzX1
A debug log where on a first (very short) session played/skipped few songs and then I tried to disconnect and reconnect with related errors on the log. I hop it is enought to locate the bug.

I see
INFO:tornado.access:200 GET /ssdp/device-desc.xml (10.1.1.111) 1.00ms
on my PC but

on my phone.

Running Windows 8 Pro, Python 2.7.5.

Installed dependencies, and launch leapcast using:

leapcast --name ComputerCast --chrome "C://Users//Adrian//AppData//Local//Google//Chrome//Application//chrome.exe"

No errors pop up, but the Cast button doesn't show up in YouTube or Google Music on my Android phone.

Terminating leapcast with CTRL+C shows:

INFO:Leapcast:Stopping HTTP server
INFO:Leapcast:Stopping DIAL server

So it appears the servers are starting correctly, but the Cast button isn't showing up.

I tried casting to the emulator, and then I opened up chrome on my mac and navigated to http://192.168.7.130:8008/apps/YouTube/run , I got a 404. How can I preview the content that is being casted.

I cannot get the app to work when I sent the chrome path( /Applications/Google\ Chrome.app on my mac) as --chrome flag. So I am manually opening up the chrome app.

Also once I start the server and then stop it , then retry starting , I always get the error - "address already in use" Looks like a bug.

First, congrats for this program.

I can get the cast button to appear in the Youtube app but not
the 2 mentionned apps.

However, both apps discover leapcast as they fetch the device XML, but the button does not appear.
I suspect the Youtube app to not use the Android Googlecast SDK, while both these app do (at least the sample app does).
I suppose they might not like something in the device XML.

Hi,

Thanks for this, I am trying to run this and I am getting the error below, am I missing something?

$ sudo python app.py --name remo 192.168.4.1 -->(not a part of my lan)

Using Windows 8 with python 2.7

Tried passing in the arg --chrome with full path to chrome (C:\Users[.my name here..]\AppData\Local\Google\Chrome\Application\chrome.exe) and it could not find chrome when I played something over chromecast.

Workaround was to put that chrome path into my PATH variable.

I'm currently working on adding UPnP-AV support to leapcast. Now I'm wondering if that is beyond the scope of leapcast. Since the project description says: "ChromeCast emulation app for any device".

my chromecast app randomly fails with messages in logcat like this:

E/MediaProtocolMessageStream(10024): error parsing message: {"type":"RESPONSE","cmd_id":2,"status":{"error":{"domain":"ramp","code":-4},"event_sequence":2}} org.json.JSONException: No value for state

leapcast (started in debug mode) prints out the following at the same time:

DEBUG:root:ReceiverChannel: [
  "ramp",
  {
    "cmd_id": 2,
    "status": {
      "error": {
        "code": -4,
        "domain": "ramp"
      },
      "event_sequence": 2
    },
    "type": "RESPONSE"
  }
]

Unfortunately I don't have a real device to test - do you have any idea if it's related to your emulator or not?

Right now, leapcast works well with YouTube being controlled by a single Android device. More than one is buggy. Follow the steps:

1. Run leapcast.
2. Open YouTube on Android. Press the ChromeCast button, select the leapcast device.
   → YouTube screen opens in leapcast (as expected), and we can control YouTube through that device.
3. Repeat step 2 on another Android device.
   → Broken. The second device cannot control the same YouTube in leapcast.
4. From the second device (the one that cannot control YouTube), press the ChromeCast button and switch back to the device, freeing up control of leapcast.
   → This sends a DELETE request, which will then close the main YouTube app on LeapCast, interrupting whatever was being played there by the first device.

AFAIK, the expected behavior is having multiple devices controlling the same ChromeCast flawlessly.

I'm not sure if this is possible, and didn't find any useful information on the web (so far).

I am able to get leapcast running properly on an old laptop, but not on raspberry pi. When trying to ask the leapcast server to play music, it gives an error "OSError: [Errno 2] No such file or directory" and the full traceback is below. The same error happens when attempting to play youtube videos.

The raspberry pi has no screen attached to it, and it's running chromium instead of google-chrome. I tried to specify xvfb-run in the leapcast's --chrome option, but I wasn't able to see any difference in behavior.

Suggestions would be most welcome. thanks!

This is really a coooool chromecast emulator, and I successfully run on ubuntu with Youtube app.
But I consult one question :
Is it really depend on Chrome browser, could I replace by other browser that support websocket(like QT webkit) ?

Dear dz0ny:
Hi, I recently study leapcast project, yet there are some parts of it i don't understand.
When websocket server receives POST request , it will open the browser. The browser will not start to play (say youtube) video until ReceiverChannel. on_message receives RAMP protocol command.
However, as I trace on_message function, I haven't found out which part of the function actually parse RAMP command to the browser. From my understanding, this function only write the message back to the client according to the tornado.web api.
I would like to know how the RAMP command communicate with the chrome browser in the leapcast program.

    Any feedback is highly appreciated. Thank you very much.

Best Regards

Is there a way to register my receiver app on LeapCast?
I'm outside of US, but i want to start developing apps for ChromeCast. While i'm waiting for my device to come here from US, is there a way to start developing with LeapCast?

It seems like shlex.split causes args to become

When you start leapcast on Debian Wheezy, you'll get the error: "socket.error: [Errno 98] Address already in use"

This is because minissdpd UPnP daemon is started automatically before any other SSDP (UPnP) program on Debian Wheezy and other Debian derivative machines.

A workaround is to locate the /usr/sbin/minissdpd PID and killing it before starting leapcast. i.e.

find the PID of running ssdp UPnP program

$ ps -ef | grep ssdp

The output will be something similar to the line below.

root 5413 1 0 09:36 ? 00:00:00 /usr/sbin/minissdpd -i 0.0.0.0

Stop the minissdpd SSDP UPnP daemon

$ sudo kill -9 5413

where 5413 in this case is the PID of /usr/sbin/minissdpd

Leapcast will then be able to run on the computer.

I'm trying to run Pandora on Leapcast.
I did a few changes in leapcast/apps/default.py, but that was not enough to make it work.
Should I explicitly mention the protocol used? (and implement it?)

Is there anything that would prevent Pandora from working on Leapcast?

Can someone provide a few hints on what to change to make it work before I start digging deeper in the code?

I don't know the exact steps to reproduce, but you may try something like this:

1. Open YouTube on leapcast.
2. Open a different app (like ChromeCast from Chrome, or Play Movies).
3. Eventually, this exception will be thrown.

Sorry I couldn't provide precise steps to reproduce it.

Hi,

My Desktop PC is running on Windows 7. I have done everything according to: https://plus.google.com/+NicandrosNicolaou/posts/8RjWfMXxje8.

When I copied every character into the cmd prompt as outlined in the last step, which is #16:

16. Run with (type in cmd)

leapcast --name VAIO --chrome "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" –-fullscreen

The screen does not display what is said in the follow step:

17. This should be displayed

INFO:root:Starting SSDP server
INFO:root:Starting LEAP server

After I entered the following into cmd (I made sure I was in the folder where leapcast is, too ----> c:\leapcast-master> ):

leapcast --name VAIO --chrome "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" –-fullscreen

I get the following display from the computer:

Traceback (most recent call last):
File "C:\Python27\Scripts\leapcast-script.py", line 9, in
load_entry_point('Leapcast==0.0.6', 'console_scripts', 'leapcast')()

ImportError: No module named requests

[END]

Will someone please tell me what I've done wrong? Do I need to change something out in step #16? What is the name-of-device mean exactly. Name of my PC? Or model name of my PC? Or do I need to remove (x86) from the path name? I have tried doing that, too, and still getting this traceback data.

Please help me, I thank you in advance.

The cast android sample App (https://github.com/googlecast/cast-android-sample)
crashes when used with leapcast and reopened once it has been closed.
I'm not sure if this is a problem with leapcast or with the cast sdk as I have no real chromecast device yet.

It can be reproduced like this:

• install sample app on android / register with leapcast
• start leapcast
• start sample app on android and cast something
• use task-manager to close sample app on android
• (re-)start sample app on android

The first time leapcast responds to /apps with status-code 200:

INFO:tornado.access:200

The second time with 302 (redirects to app):

INFO:tornado.access:302 GET /apps 

The following stacktrace is produced by the sample app on android:

The same problem can also be observed using Google Music on Android. It does not crash when opened the second time, but it refuses to show the cast button, even when leapcast is restarted. It only shows up again when the Music App is restarted.

I see no way to uninstall the program, am I missing something, can I please get some direction?

So, I tried the older versions of YouTube app with Leapcast (Which is thankfully updated and now working) but after i updated my youtube app to a new version (5.0.21), it started doing this: (While trying to stream a video)

(And yes, I properly did the setup, using this one https://gist.github.com/eyecatchup/6219118)

Here is what I found so far: https://plus.google.com/117916055521642810655/posts/b3wCmToPehK

It would be great if the simulator could support this somehow, maybe with integrating with a media player.

I'm running leapcast under Win7 X64 and everything works fine (cast icon is shown in android/chrome) and I can select it as target. But when I play a video, I'm getting a "The system cannot find the file specified" exception.

I'm using the following command to start leapcast:

python app.py --name "MyCast" --chrome "C:\Users\DieBagger\AppData\Local\Google\Chrome\Application\chrome.exe"

Here's the full exception:

I have an old htpc with a very slow cpu, but an nvidia ion gpu that can play play full hd, bluray quality video. Video players that support vdpau or vaapi acceleration run very well on this thing. I tried out leapcast, the slow framerate makes me think it's not hardware accelerated. Is this true? If so, is it possible to add acceleration?

When casting to Leapcast, the cursor remains on screen in front of the video.

Ideally it would be removed from the screen automatically.

Win7x64 Python2.7 Chrome 28

Hello,
I made some changes in leapcast codes, in code, but when I try to executes the program (leapcast or main.py) it just executes the current code, and not the changed code.
Any reason for that? Anyway to make changes in my dir and executes it?

On linux (mint14) and finding your code fun to play with. From youtube app on my android smartphone I get the chromecast button and it opens google-chrome. However there is a title bar at the top and the cinnamon panel at the bottom. If I press F11 it goes fullscreen, but won't come back.

Also when the video stops playing, chrome stays open with a screen inviting me to play another video. Can I close it some way?

Thanks.

Running leapcast on Windows and restarting it frequently, at some point discovery will not work anymore until I disable/enable the network interface in the Windows network settings.

I have several other UPnP software listening on port 1900 and none ever had this problem, being also restarted several times.

I am not able to cast from a tab of chrome to leapcast. I have tried running leapcast in root as well.
The error on chrome is :
"Unable to cast to HAD.
An unexpected error occurred. Please try the following:
Try to cast again

And the output of leapcast is the following :

I am running leapcast on ubuntu 13.04 .

I constantly receive this error when i try to initiate leapcast.

Any ideas where i'm going wrong

Windows 7, Python 2.7.5

If using the --iface option to specify an interface, 127.0.0.1 will not be bound and
the receiver connection to ws://localhost:8008/connection will fail.

When I try to connect from the Chromecast app it fails and leapcast has this 404 errors:

WARNING:tornado.access:404 GET /setup/eureka_info?options=detail (192.168.0.9) 0.50ms
WARNING:tornado.access:404 GET /setup/eureka_info?options=detail,sign (192.168.0.9) 0.50ms

WARNING:tornado.access:404 GET /setup/eureka_info?options=detail,sign (192.168.0.9) 0.48ms

I grepped the source and there seems to be a eureka URL but not eureka_info so I guess Google must have changed the API.

Let me preface this by saying that, in general, I don't know what the hell I'm doing... I wrestled with python on Windows 7 to get it to do what I want, and after lots of googling and trial-and-error, I think I got leapcast installed correctly.

So anyway, I go to my windows command prompt, type in:

python

import leapcast

leapcast --name Chromecast --chrome "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"

But I get a syntax error. The final step looks like this:

leapcast --name Chromecast --chrome "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"
  File "<stdin>", line 1
    leapcast --name Chromecast --chrome "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"
                             ^
SyntaxError: invalid syntax

And if I enter just "leapcast," I get this:

leapcast
<module 'leapcast' from 'c:\users\matthew\documents\github\leapcast\leapcast\__init__.pyc'>

So maybe someone knows what's up, but I get the feeling it's user error. =/

Hi,

after returning from standby on windows 7 the program stops working. Logging says "WARNING:root:App already closed in destroy()" from def stop_app(self): at leap_factory.py line 169

No idea yet why this happens...
