Dear All, I'm sorry that taking up your time. Im new in (PJ)SIP and I can't find an answer to the questions I have. 1. I can't find way to change capture device id (video and audio) before calling. 2. I can't understand when I should use pjsua_call_set_vid_strm? How can I say that SDP negotiation was finished in on_call_media_state? Who should send reinvite/update me or pjsua inside will send? What should I send reinvite or update? 3. I launched vidgui example and I tryed to call with video to another sip client (not pjsip) it doesn't work. I see in log that SDP negotiation was started, but than I have "deadlock" - no more log's messages appears. Where should I investigate? Thanks for any advice. -------------- next part -------------- An HTML attachment was scrubbed...
