Hi -<br><br>Could someone write a few words on the state of video calling in FS? <br>The no media<br>mode works fine, but I'm interested in being able to take do things
with <br>the media streams.<br><br>What I've done so far:<br>- create an H.264 passthrough codec, derived from the G.729 one;<br>- tamper with the video codec negotiation code to get that bit to work.<br><br>What I'm not sure of is how much else is implemented or not and, before
<br>I hide in a dark<br>corner with a large pot of coffee to work through what's done and
what's <br>not, I figured I<br>might ask..<br><br>Cheers --<br><br>Dave<br><br>-- <br>David Knell, Director, 3C Limited<br>T: 020 8114 8901 F: 020 8692 0677 M: 07773 800623<br><a href="http://www.3c.co.uk" target="_blank">http://www.3c.co.uk</a> <br><br><br>_______________________________________________<br>Freeswitch-users mailing list<br><a ymailto="mailto:Freeswitch-users@lists.freeswitch.org" href="mailto:Freeswitch-users@lists.freeswitch.org">Freeswitch-users@lists.freeswitch.org</a><br><a href="http://lists.freeswitch.org/mailman/listinfo/freeswitch-users" target="_blank">http://lists.freeswitch.org/mailman/listinfo/freeswitch-users</a><br>UNSUBSCRIBE:<a href="http://lists.freeswitch.org/mailman/options/freeswitch-users" target="_blank">http://lists.freeswitch.org/mailman/options/freeswitch-users</a><br><a href="http://www.freeswitch.org" target="_blank">http://www.freeswitch.org</a><br></div><br></div></div><br>
