| Libjingle | |
| Libjingle is a set of components provided by Google to interoperate with Google | |
| Talk's peer-to-peer and voice capabilities. This package will create several | |
| static libraries you may link to your project as needed. | |
| -talk - No source files in talk/, just these subdirectories | |
| |-base - Contains basic low-level portable utility functions for | |
| | things like threads and sockets | |
| |-p2p - The P2P stack | |
| |-base - Base p2p functionality | |
| |-client - Hooks to tie it into XMPP | |
| |-session - Signaling | |
| |-phone - Signaling code specific to making phone calls | |
| |-third_party - Components that aren't ours | |
| |-mediastreamer - Media components for dealing with sound hardware and | |
| | voice codecs | |
| |-xmllite - XML parser | |
| |-xmpp - XMPP engine | |
| In addition, this package contains two examples in talk/examples which | |
| illustrate the basic concepts of how the provided classes work. | |
| The xmllite component of libjingle depends on expat. You can download expat | |
| from http://expat.sourceforge.net/. | |
| mediastreamer, the media components used by the example applications depend on | |
| the oRTP and iLBC components from linphone, which can be found at | |
| http://www.linphone.org. Linphone, in turn depends on GLib, which can be found | |
| at http://www.gtk.org. This GLib dependency should be removed in future | |
| releases. | |
| Building Libjingle | |
| Once the dependencies are installed, run ./configure. ./configure will return | |
| an error if it failed to locate the proper dependencies. If ./configure | |
| succeeds, run 'make' to build the components and examples. | |
| When the build is complete, you can run the call example from | |
| talk/examples/call and the pcp example from talk/examples/pcp. | |
| Relay Server | |
| Libjingle will also build a relay server that may be used to relay traffic | |
| when a direct peer-to-peer connection could not be established. The relay | |
| server will build in talk/p2p/base/relayserver and will listen on UDP | |
| ports 5000 and 5001. See the Libjingle Developer Guide at | |
| http://code.google.com/apis/talk/index.html for information about configuring | |
| a client to use this relay server. | |
| STUN Server | |
| Lastly, Libjingle builds a STUN server which implements the STUN protocol for | |
| Simple Traversal of UDP over NAT. The STUN server is built as | |
| talk/p2p/base/stunserver and listens on UDP port 7000. See the Libjingle | |
| Developer Guide at http://code.google.com/apis/talk/index.html for information | |
| about configuring a client to use this STUN server. |
