In chan_sip.c search for the<BR>function add_vcodec_to_sdp (around line 10316 in 1.8 branch at the<BR>moment). At the end of the function there is a comment:<BR> /* Add fmtp code here */<BR><BR>Add this lines after the comment:<BR> if (codec & 0x200000) {<BR> ast_str_append(a_buf,0,"a=fmtp:%d<BR> profile-level-id=42801f;max-mbps=245000;max-fs=8192;<BR>
packetization-mode=0\r\n",rtp_code);<BR> }<BR><BR>I did not test that. I not even tried to compile with that lines ...<BR>So no guarantee for anything. I just had a look to the source in<BR>chan_sip.c and your SIP trace and tried to build together some lines<BR>of code. It is not a solution for all video problems. It's only a hack<BR>for your situation with the Lifesize system.<BR>I do not have access to such a Lifesize conferencing system at the<BR>moment. But I know someone and maybe I will do a test in a few weeks.<BR><BR>Regards,<BR>Gunnar<BR><BR><BR>--<BR>_____________________________________________________________________<BR>-- Bandwidth and Colocation Provided by http://www.api-digital.com --<BR><BR>asterisk-video mailing list<BR>To UNSUBSCRIBE or update options visit:<BR> http://lists.digium.com/mailman/listinfo/asterisk-video<BR></DIV></DIV></div></body></html>
