Hi all I've read Media Flow, there is the diagram(http://trac.pjsip.org/repos/wiki/media-flow): [cid:image003.png at 01CF7B3B.6E29BDF0] I have some question about video call. 1, I can understand it in the voice call, but when make a video call, does it work in the same way? 2, Video calls, including images and sound. Are image and sound are recorded separately? 3, How sound and image are synchronized Best Regards, jason.chen -------------- next part -------------- An HTML attachment was scrubbed...
