[Psi-Devel] Jingle A/V

[Justin Karneges]

Tonight I committed the first round of our new Jingle audio/video feature.  It 
is intended to replace our earlier libjingle-based implementation.  I made a 
successful test call to a development version of Pidgin, and I'm still kind 
of shocked that it worked. :)  While Pidgin and Psi are sharing GStreamer 
code, the XMPP/ICE layers are not shared, so this is was an excellent interop 
test.

It is VERY experimental.  Currently only audio is supported, and Psi has to 
start the call.  You might have to restart Psi to make a call if one fails.  
There's also 80 ways to crash it, there's no error checking, Psi doesn't 
gracefully terminate calls, etc.  Tomorrow (and in time for the XMPP Summit), 
my goal is to make the code slightly less craptastic, and perhaps support 
video.

To use it, you need a separate checkout of PsiMedia.  Then, add 
PSIMEDIA_DIR=/path/to/psimedia in Psi's conf.pri file.  GStreamer 
dependencies are hard-coded.  Edit psimedia/gstprovider/gstconf.pri to change 
them.  With the main window focused, press ctrl+shift+N to configure your 
devices.  To use STUN, set the PSI_STUNADDR environment variable to the IP 
address of a STUN server.

Have fun,
