Hello list,
There are now some post-holiday-changes for the SIP-Gaim-plugin
available:
1) network detection
2) Gstreamer 0.10
1)
I've now implemented initial support for network detection events in
SIP-Gaim-plugin for OSX. Plugin creates another thread for OSX's run
loop and registers itself (callback) for an event indicating that IP
address has changed. We need to use this second thread for OSX run
loop because the plugin is attached to glib's event loop, too.
At this point several things happen when the network is changed
(example: we're in WLAN but switch to office ethernet):
OSX initiates the event and callback registered in ssip.c. Thread
handling this callback raises a flag address_changed in ssip_t
structure and starts nua_shutdown(). Shutdown is continued in
nua_r_shutdown (handled by the glib thread) and the address_changed
flag causes plugin to restart nua by nua_create(). nua_register()
follows and almost everybody is happy.
This, of course is quite nasty - we lose all the dialogs and our
registration. The proper way to do this is to tell tport_tbind that
it should recheck our primary addresses and update them without
touching dialogs (by shutdown+create) etc. One possibility would be
to implement the whole logic in su_localinfo.c as this clearly is
local info. Commentados?
So, if somebody is excited about this it would be nice to have the
same functionality for Linux and Windows, too. There are some quite
comprehensive pointers for SENS API of Win2K and friends:

2)
I've also copy-pasted-modified sofsip-cli's media part for the
plugin. I've been able to have playback working for 1 sec, followed
by the silence. Capture side is most probably OK but as I now
desperately try to be a happy Mac user I don't have it working for
OSX, BUT it might be OK in Linux (when you ununcomment my #if 0's for
the capture). The playback problem might be similar to what Kai has
experienced with ALSA and sofsip-cli with Gst 0.10.
The changes are in darcs, and the ChangeLog follows in the bottom.
Regards,
Martti
