Hi, when reading pjmedia Main flow (playback callback) here http://trac.pjsip.org/repos/wiki/media-flow In the main flow (playback callback), when the Sound device needs another frame to be played by the speaker, it will call play_cb(). Then the conference bridge will call pjmedia_port_get_frame() . After the bridge finishes processing all of these, it will then return the mixed signal for slot zero back to the original pjmedia_port_get_frame() call, which then will be processed by the sound device. Why is there "pjmedia_port_put_frame()" here ?? I think it is for the recording callback flow ? And what is the conference bridge ? -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
