Hi all, I got the message in the subject when playing wavs to a call from the EOF Callback. I already saw the thread http://www.pjsip.org/pipermail/pjsip/2007-July/003916.html, but my problem is a little bit different, the application doesn't really deadlock, it just gives that message in the debug (level 4) and pjsua_call_get_conf_port() returns PJSUA_INVALID_ID instead of the conference port. The thread that gets this message is the "clock", thats handling the EOF callback. This problem happens if the callback for incoming calls takes a little long to finish (around 100 ms), and it happens even when there is no hangups, like only incoming calls. I'm not using the pjsua player, I'm creating it directly with pjmedia. Right now I'm keeping the conference port number stored in a variable and I update it on every change of media state, since the callback for media state is handled by pjsua thread, and the problem is solved. Is this the best solution? Is there a way out of this without having to use timers? Thanks for all help, Thiago Abra sua conta no Yahoo!
