A full-featured Yahoo client for LINUX with voice chat and webcam support. Mission: To focus on thorough Y! support on Linux only. Philosophy: Trying to do multi-protocol / cross-platform clients slows progress and results in half-baked support - One protocol, one OS...done well.

NEWS  :


pY! Voice Chat is written in Python and currently works with GYach Enhanced. It requires Python 2.2 or better and PyGtk-2 1.99/2.00 for Gtk-2 or PyGtk 0.6.9 for Gtk-1. It uses PyTSP and PyESD for playing the TrueSpeech(tm) sound format transmitted from the Yahoo voice chat servers. Currently, pY! Voice Chat only plays sound through the ESD (ESound Daemon), so you will need ESound to use pY! Voice Chat. There are NO plans to provide support for other sound systems, such as OSS, Alsa, SDL, YIFF, etc. (and don't ask me to port it to those systems - I don't use them, so I could really care less.) See the 'README' file below for specifics on pY! Voice Chat capabilities, limitations, and system requirements. See the bottom of the page for screenshots. pY! Voice Chat comes with gettext foreign language support and a Spanish translation - so most of the screenshots are in Spanish. pY! Voice Chat currently supports almost all of the features of Yahoo's voice chat; however, the application is still experimental: Sending/recording sound to be sent to Yahoo's voice chat server produces sound that many Windows users tell me sounds like it's 'breaking up'. So, if you talk on the mic, it will probably be a little scratchy and break up alot.. (I plan to fix this on my own personal copy, but I doubt I'll keep uploading new versions.) If you would like to translate pY! Voice Chat into your own language, grab the latest Gettext translation file here, add your translations, and email it back to me.

WHAT YOU NEED TO RUN THE pY! Voice Chat - GYach Enhanced SETUP:
Either:
    gyach-enhanced_pyvoice-binary-X.X.X_i586.tar.bz2 (Compiled, Intel)
    OR
    gyach-enhanced_pyvoice-binary-X.X.X_i586.RPM (Compiled, Intel)
    OR
    gyach-enhanced_pyvoice-source--X.X.X.tar.bz2 (Source)
And:
    gyach_enhanced_fonts1.tar.bz2
    gyach_enhanced_fonts2.tar.bz2

(The 'gyach-enhanced_pyvoice' packages contain the necessary PyESD/PyTSP libraries, py! Voice Chat, GYach Enhanced, and the necessary TrueSpeech(tm) codec.) All are available in the download area. The package names above may vary on the download site, but you should get the general idea.


ATTENTION - DEVELOPERS LOOKING TO BUILD YAHOO! VOICE CHAT PROGRAMS:
Although pY! Voice Chat was made for and works well with GYach Enhanced, pY! Voice Chat does not require GYach Enhanced. In fact, pY! Voice Chat is an external application that can technically work with ANY Yahoo! chat client that is modified to work with pY! Voice Chat. If you are interested in getting pY! Voice Chat to work with another Yahoo! chat client, have a look at the files 'voice_chat.c', 'conference.c', 'main.c' (also callbacks.c and yahoochat.c) in the GYach Enhanced source code package. Also, for people looking to build voice chat programs for Yahoo, read the technical documents for pY! Voice Chat (toward the bottom of this page). The documents contain very detailed information about the Yahoo! voice chat protocol. pY! Voice Chat consists of a library (pyvoice.py) and a user interface (pyvoiceui.py). The majority of the documentation about the Yahoo voice chat protocol is in the 'pyvoice.html' file below.

IF YOU WANT TO HELP...
If you want to do me a BIG favor, re-post the 'html' documents about the Yahoo! voice chat protocol on other servers (just to make sure there are always 'backup' copies for developers in case Yahoo! tries to have these copies removed). I HOPE they would never do that, but big companies do mean things, so I want to make sure this information is always out there and this information always exists SOMEWHERE. So, I would greatly appreciate if people would 'mirror' the 'pyvoice.html' document below to ensure this information never gets permanantly 'silenced'. If you really want to help, mirror the source code too. Also, language translations for both pY! Voice Chat and GYach Enhanced are welcomed (see the 'README' file below.)

DOCUMENTATION
Listen: I've gotten emails from people WHINING that these protocol docs "are for Python, where's are the voice chat protocol docs?" These ARE the voice chat protocol docs: The pyvoice.html file explains in detail, byte-for-byte the structure of EVERY packet the client needs to send/read in order to make use of Yahoo's voice chat servers. Read the COMMENTS in the 'pyvoice.html' file. If you are too lazy to do that, don't bother! I'm not going to hold your hand and show you how to do it. The protocol docs assume that you already know that Yahoo uses the RTP protocol and that you already know RTP. If you don't know what RTP is, find out about that first. Just because these docs come from a Python program does NOT mean the protocol changes for C, Java, etc. Use common sense to apply it to whatever language you write in and take the time to understand the way I did - hex bytes are hex bytes, no matter what language. And, if these aren't enough, do what I did when I had NO information to start with: Run Ethereal and do some packet sniffing. If you really want to help keep these docs open, REPOST them to other sites in case somebody decides they want these copies removed.
