As you know, the video conference can support deliver the pc's desktop to the conference member. The client can receive 3 streams, there are audio,video,application. You should see there are three media types in pjsip: PJMEDIA_TYPE_AUDIO,PJMEDIA_TYPE_VIDEO,PJMEDIA_TYPE_APPLICATION. you are right, the details about dual video stream is litter. So I seek help here.
