Hi Benny; Is it better to create two session to add video to pjsip rather than creating secondory video stream in one session.. If i create one session with two streams ,there will be one endpt and i am thinking how to send video rtp packets. If i create two session there will be second media thread which i can use send and receive video media rtp packets. If i use one session with audio and video streams should i implement thread to send and receive rtp packets? or am i able to use existing media thread?
