Good day! I'am experimenting with SIP video calls (using VP8 video codec). Ordinary audio+video calls works very well (audio recordered and video passed through). But if I try to make only video call, i.e. SDP contains only video media, than I got an error and channels hang up: 2013-10-31 17:00:38.494743 [DEBUG] sofia.c:5708 Channel sofia/internal/sip:1008@10.10.104.125:10018 entering state [ready][200] 2013-10-31 17:00:38.494743 [DEBUG] sofia_glue.c:5382 Video Codec Compare [VP8:99]/[H264:97] 2013-10-31 17:00:38.494743 [DEBUG] sofia_glue.c:5382 Video Codec Compare [VP8:99]/[VP8:99] 2013-10-31 17:00:38.494743 [ERR] sofia_glue.c:3025 No audio codec available 2013-10-31 17:00:38.494743 [DEBUG] sofia_glue.c:2975 Set VIDEO Codec sofia/internal/sip:1008@10.10.104.125:10018 VP8/90000 0 ms 2013-10-31 17:00:38.514745 [ERR] sofia.c:6464 RTP Error! 2013-10-31 17:00:38.514745 [NOTICE] sofia.c:6465 Hangup sofia/internal/sip:1008@10.10.104.125:10018 [CS_CONSUME_MEDIA] [DESTINATION_OUT_OF_ORDER] 2013-10-31 17:00:38.514745 [DEBUG] switch_channel.c:3130 Send signal sofia/internal/sip:1008@10.10.104.125:10018 [KILL] Incoming SDP information looks like this: v=0 o=- 1383224434 1 IN IP4 10.10.104.125 s=Test/2.0beta263 c=IN IP4 10.10.104.125 t=0 0 m=video 5000 RTP/AVP 31 34 110 109 102 103 96 108 107 b=AS:768 b=AS:768000 a=rtpmap:31 h261/90000 a=fmtp:31 CIF=1;QCIF=1 a=rtpmap:34 H263/90000 a=fmtp:34 F=1;CIF=1;CIF16=1;CIF4=1;maxbr=7680;QCIF=1;SQCIF=1 a=rtpmap:110 H263-1998/90000 a=fmtp:110 D=1;F=1;I=1;J=1;CIF=1;CIF16=1;CIF4=1;maxbr=7680;QCIF=1;SQCIF=1 a=rtpmap:109 H264/90000 a=fmtp:109 max-fs=9000;max-mbps=270000;profile-level-id=428028 a=rtpmap:102 H264/90000 a=fmtp:102 packetization-mode=1;max-fs=9000;max-mbps=270000;profile-level-id=428028 a=rtpmap:103 H264/90000 a=fmtp:103 packetization-mode=1;max-fs=9000;max-mbps=270000;profile-level-id=640028 a=rtpmap:96 raw/90000 a=fmtp:96 rate=90000;height=288;width=352;colorimetry=BT601-5;depth=8;sampling=YCbCr-4:2:0 a=rtpmap:108 X-MX-VP8/90000 a=fmtp:108 x-mx-max-size=1920x1200 a=rtpmap:107 VP8/90000 a=fmtp:107 max-fs=9000 a=rtcp-fb:* pli fir tmmbr tstr freeswitch local SDP: v=0 o=FreeSWITCH 1383203862 1383203863 IN IP4 10.10.104.125 s=FreeSWITCH c=IN IP4 10.10.104.125 t=0 0 m=video 32038 RTP/AVP 98 99 a=rtpmap:98 H264/90000 a=fmtp:98 packetization-mode=1;max-fs=9000;max-mbps=270000;profile-level-id=640028 a=rtpmap:99 VP8/90000 a=fmtp:99 max-fs=9000 and remote SDP: v=0 o=- 1383224434 1 IN IP4 10.10.104.125 s=SimpleOPAL/3.12.7 c=IN IP4 10.10.104.125 t=0 0 m=video 5002 RTP/AVP 99 b=AS:16000 b=AS:16000000 a=rtpmap:99 VP8/90000 a=fmtp:99 max-fs=9000 a=rtcp-fb:* pli fir tmmbr tstr -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Video-only-call-tp7595976.html Sent from the freeswitch-users mailing list archive at Nabble.com.
