Hello, first of all, please excuse my English... My school dissertation theme is prepare SIP modul for Mozilla Thunderbird. At this moment, I have SIP programmed using JavaScript and Mozilla components. Now, I need a library for RTP and media stream. From all, that I found with Google, I like the most PjMedia. My idea is, that I wrap PjMedia into XPCOM and I will have 3 functions: For example: - createServer() - that create on localhost RTP server and return SDP, that I can post in SIP message - connectToServer(sdp) - that connect to server, which I pass as SDP in function argument. - close() - that close current media stream. Bud I am very new to PjMedia and XPCOM. If my idea can be implemented, is there anybody who could help me with implementing this three functions? As simple as it can be :) Or is there some tutorial, that describe my requirement. I looked in sample apps, but there I didn't found anything, that help me. I will be grateful for any response...
