Hi, Nanang! I build pjsip 2.0 beta. Video API really changed. Preview window moving become easier. I even can move preview window as usual window - good. BUT there is no video during call. I created account and try to call with turned on and turned off video preview. I use Microsoft web cam NX-6000. I saw SDP in PJSUA logs. v=0 o=root 1140926841 1140926842 IN IP4 192.168.2.134 s=Asterisk PBX 1.6.2.7-1ubuntu1.2 c=IN IP4 192.168.2.134 t=0 0 m=audio 12528 RTP/AVP 0 96 a=rtpmap:0 PCMU/8000 a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv m=video 0 RTP/AVP 96 I thought about this. and my opinion is "I didn't configured SDP for video stream correctly". After answer with turned on video preview - my video preview of my web cam moved to top left part of screen.
