Aha! I wasn't serializing the port number on NiceCandidate.addr and NiceCandidate.base_addr! I added that, as you suggested, and I'm now sending data between my agents! td <div class="gmail_quote"> On Mon, Aug 30, 2010 at 3:24 PM, Youness Alaoui <<a href="mailto:youness.alaoui@collabora.co.uk">youness.alaoui@collabora.co.uk</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div class="im">On 08/30/2010 06:20 PM, Tony Di Croce wrote: > > Ok, well, I guess that's not my problem then! > > I feel like I'm very close... > > I have two agents... both of which are getting their local candidates, > serializing them and sendthing them to the other... > > Both of them are also sending their local credentials to each other and > calling "nice_agent_set_remote_credentials()" on them... > > They are both talking to my stun server, and I believe that all of the > information is being serialized and deserialized correctly (it's safe to > use nice_address_to_string() and nice_address_set_from_string() to > serialize and deserialize the NiceCandidate->addr and > NiceCandidate->base_addr members right?)... </div>So far good, yes, you can serialize them with the to_string and from_string. Just don't forget to get/set the port on the NiceAddress. <div class="im">> > BTW, do I need to set the "NiceCandidate->username" and > "NiceCandidate->password" fields if I am seperately sending the > credentials ( I currently am both sending them as part of my > NiceCandidate serialization process and seperately for calls to </div>> set_remote_credentials())....? no, you don't need to.. some compatiblity modes (like google, or MSN) have a username/password different for each candidate, but that's from the old draft of ICE (draft 6) and it's not used anymore, now only the get/set credentials is needed. If you set a user/pass on the candidate itself, it will override the global stream credentials for that candidate. <div class="im"> > > The behaviour that I'm seeing is that my componet state never changes to > 4... it goes right from 2 to 5... then a send() of course fails... </div>yes, 5 is FAILED, so something goes wrong.. if you run your program with the environment variable "NICE_DEBUG=all" set, and send me the logs from both sides for the same call, I'll have a look at see why it failed. You can send the logs to me directly in this case :) Youness. <div class="im">> > td > > On Mon, Aug 30, 2010 at 2:47 PM, Youness Alaoui </div>> <<a href="mailto:youness.alaoui@collabora.co.uk">youness.alaoui@collabora.co.uk</a> <mailto:<a href="mailto:youness.alaoui@collabora.co.uk">youness.alaoui@collabora.co.uk</a>>> <div><div></div><div class="h5">> wrote: > > On 08/30/2010 05:43 PM, Tony Di Croce wrote: > > In the "test-thread.c" example application that is included in the > > libnice source tree a number of threads are created... > > > > My current thinking is that "lthread" and "rthread" are needed to > > implement the main loop of the agents themselves...
