This could be a first problem, you didn't define a STUN server, however
it tries to use it.
In file ssc_sip.c, function priv_create_ssc_media, around line 300:
if (res_impl) {
g_object_set(G_OBJECT(res_impl), "stun-server", conf->ssc_stun_server,
NULL);
g_object_set(G_OBJECT(res_impl), "stun-domain", userdomain, NULL);
}
If you don't define conf->ssc_stun_server then it's NULL, but userdomain
is never NULL, so in ssc_media_gst.c, function priv_setup_rtpelements,
near line 470:
if (self->sm_stun_server || self->sm_stun_domain) {
self->sm_netsocket = NULL;
netsocket_type = FARSIGHT_NETSOCKET_STUN_TYPE;
netsocket = g_object_new (netsocket_type,
"sockfd", pri_sockfd,
"aux-sockfd", aux_sockfd,
"server", self->sm_stun_server,
"domain", self->sm_stun_domain,
NULL);
[...]
It always uses STUN.
I fixed it in ssc_sip.c changing the code to:
if (res_impl) {
g_object_set(G_OBJECT(res_impl), "stun-server", conf->ssc_stun_server,
NULL);
if(conf->ssc_stun_server){
g_object_set(G_OBJECT(res_impl), "stun-domain", userdomain, NULL);
} else {
g_object_set(G_OBJECT(res_impl), "stun-domain", NULL, NULL);
}
}
You can fix it in ssc_media_gst.c if you prefer.

This one could be a second problem. It looks for the gst element
alsasink but the first one that it finds is AlsaSPDIFSink but it's the
wrong one.
In the file ssc_media_gst_utils.c the function
ssc_media_create_audio_sink near line 205 checks only if the string alsa
is in the longname, so for it AlsaSPDIFSink and AlsaSink are the same:
if(strstr(klass_tags, "Sink") && strstr(klass_tags, "Audio") &&
strstr(gst_element_factory_get_longname(factory), type)){
res = gst_element_factory_create(factory, "audiosink");
break;
}
I fixed it in a quick and dirty way like this (I'll have to think for a
better way though :-)):
if (strstr(klass_tags, "Sink") && strstr(klass_tags, "Audio")){
if(strstr(gst_element_factory_get_longname(factory), type) &&
!strstr(gst_element_factory_get_longname(factory), "S/PDIF ALSA") ){
res = gst_element_factory_create(factory, "audiosink");
break;
}
}

problem. Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Never had this error, so I don't know how to deal with it.
Hope this helps.
