Update Sept 2015: This blog is over two years old at this point and some kind readers have posted updated links and info in the comment section down below. Be sure to read through those prior to following this guide! Thanks and enjoy!
What is Pithos?
Pithos is a Linux application that allows you to stream music from Pandora.com without having to use the Pandora web player, which is more resource intensive and mostly featureless unless you pay for a Pandora One account. With Pithos you can use the media keys on your keyboard, show artist/song information via desktop notifications, and best of all – remove all advertisements. You can find more information about Pithos here, including a list of all of its other features. What you won’t find on the Pithos website is a Windows installer, which is what this guide is for.
List of Programs We Will Need
If you are running 64-bit Windows, make sure you download the 64-bit versions.
I wasn’t able to run Pithos using the 32-bit versions in Windows 7 64-bit.
2. Either the 32-bit or 64-bit version of the GStreamer SDK Runtime from:
Make sure you get the file ending in (Runtime) for your specific version.
For example, GStreamer SDK 2012.11 (Brahmaputra) for Windows 64 bits (Runtime).
Download and run the Python 2.7.3 installer using one of the two links found above.
Make sure you install Python to the default directory, C:\Python27\
All the other default installation settings are fine.
Once Python is installed, download and run the correct GStreamer SDK Runtime installer.
When asked what type of installation you want, choose Custom.
On the Custom Install page make sure you do all of the following:
1. Scroll down the list and make sure that none of the items up to Snappy Media Player
have a red X to the left of them.
2. Click the red X next to ‘GStreamer restricted codecs with potential patent issues in some
countries’ and then click ‘Will be installed on local hard drive’.
3. Make sure the installation directory is C:\gstreamer-sdk\
Here is what it should look like.
After the GStreamer install finishes, download and run the Pithos for Windows installer.
All the default install settings are fine.
The basic installation is now complete.
If you are using the 32-bit version, you should be able to find Pithos in your list of programs in the Start Menu and run it successfully. If you are interested in using the media keys on your keyboard or want to make Pithos show artist/song/album info via desktop notifications when songs change, then scroll down to the Optional Functions Setup section.
If you are using 64-bit then you need to do one more thing before Pithos will start, then you can play with the extra features.
There are two lines in Pithos.bat that are incorrect.
Open up My Computer from the Start Menu –> Browse to C:\Program Files (x86)\Pithos –> Right-click Pithos.bat –> Click Edit
Pithos.bat should now be open in Notepad.
We need to change two lines in this batch file.
Scroll down until you see
REM For some reason the GStreamer SDK doesn’t define the environment
REM variables globally, so we just have to cheat if we can’t do it
REM the ‘correct’ way
if exist C:\gstreamer-sdk.10\x86\bin goto found_pygst_x86_hardcoded
if exist C:\gstreamer-sdk.10\x64\bin goto found_pygst_x64_hardcoded
and change the line
if exist C:\gstreamer-sdk.10\x64\bin goto found_pygst_x64_hardcoded
if exist C:\gstreamer-sdk.10\x86_64\bin goto found_pygst_x64_hardcoded
Then, two blocks of text later you should see
set GST_VIA=hardcoded path
change the line
Close notepad and click Save on the dialog box that pops up.
Now double click Pithos.bat and see if it loads correctly.
After changing these two lines of code, Pithos loaded correctly for me in Windows 7 64-bit.
Optional Functions Setup
Some keyboards, like my Logitech G510, just don’t seem to work with pyHook. Not sure what the problem is, might even be a bug with Pithos. So if you follow all these steps and your keys still don’t work, you are not alone. Try googling for solutions, if you find one, post a comment. Honestly, the media keys are just a luxury for when you are gaming or using some other full-screen application. You can always just right click the Pithos icon in the taskbar to access all the control functions anyways.
If you are using 32-bit then skip to the ‘For 32-bit and 64-bit section’.
For 64-bit Windows Only
For some reason the 64-bit Python installer doesn’t make a new registry key that tells other programs where Python was installed. We have to do this ourselves. It’s silly, but it is easy to fix. I made a .reg file that will create the registry key for you, which you can download here. It only adds one key to the registry and nothing else, I promise. Feel free to right click the file after you save it and hit edit so you can verify that it’s safe. To run it, just save it to your desktop or wherever is convenient and then double click it. You can now skip ahead to the ‘For 32-bit and 64-bit section’.
If you enjoy doing things yourself, or are paranoid about running registry files from random blogs on the internet :P, you can use the following, slightly more complicated, method.
1. Run regedit from the Windows Start menu run option or search box.
2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.7
3. Right click the 2.7 key, select New, and then Key.
4. Name the new key InstallPath
6. Make sure you still have the InstallPath key highlighted to the left.
7. Right click the value labeled (Default) in the panel to the right.
8. Click Modify…
9. Enter C:\Python27 into the ‘Value data:’ field and click OK.
Your screen should now look similar to this.
Go ahead and close regedit.
For 32-bit and 64-bit
Download and run the pyHook installer.
If you see the error message below, then you are still missing a registry entry pointing programs to where Python was installed. So go back up to the previous section and try again.
If the installer completes successfully then,
Download and run the pyWin32 installer.
Now that both pyHook and pyWin32 are installed, run Pithos, click the icon with a wrench, and then click Settings. Then just check the following box and click OK.
You should now (hopefully) be able to use your media keys.
Pithos uses Growl for desktop notifications.
First, we need to download two files from:
The website disables linking to files directly and it is incredibly long, so you will have to use the links below and get the files yourself.
If you are running 64-bit and encounter an error about not being able to locate the Python 2.7 install directory, follow the ‘For 64-bit Only’ section for setting up media keys (scroll up) and then try installing both files again.
Now that distribute and pip are installed, we need to install gntp. This is basically a service that runs in the background and lets programs tell Growl that they want to popup notifications on your desktop.
To install it, open a command prompt window. Usually done by typing cmd in the Start Menu run or search box and hitting enter.
With command prompt open, do the following:
1. Type cd c:\python27\scripts and hit enter.
2. Type pip install gntp and hit enter.
You should see a message saying that gntp install successfully.
Close the command prompt window.
Download and install Growl for Windows
All the default settings are fine.
Now run Growl, there is a probably a shortcut on your desktop.
Run Pithos, click the wrench icon, click Settings, and check the ‘Show Growl notifications’ box.
Try switching tracks in Pithos and you should see a desktop notification show up with the current song information. If nothing shows up, close and reopen Pithos, and try again.
Mine looks like this.
Now just enjoy some great music for free :)
