Hi,I am making a project and it will use multicast technology. I know pjmedia can be used to facilitate RTP/RTCP unicast or multicast communication. I have found a simple example(http://www.pjsip.org/pjmedia/docs/html/page_pjmedia_samples_streamutil_c.htm) and it uses unicast communication . Can I change it into multicast communication easily ? How to open multicast communication instead of unicast one? Thank you in advance -------------- next part -------------- An HTML attachment was scrubbed...
