Hi,|I went through the implementation of RTP using lwIP socket programming for which I have read the author is Goldsimon. If I am quite correct is it the same Simon Goldschmidt. If in that case I would have a question for him. My question is does this project with root name contrib / apps / rtp / rtp.c just implement only RTP or it also includes RTCP. I am quite confused, since lwIP implementation is quite compact I need to post this question. As far as I can see it only implements RTP like sending and receiving RTP packets, also it is for socket programming. I am planning to implement the RTP/RTCP using lwIP Raw API. Since your project gives a good overview of implementing it on lwIP TCP/IP stack, I am planning to follow your approach for my implementation. On the other hand if you say there is entirely different implementation for RTCP, then please let me know that as well.
