RTP packets detected as UDP
8 juillet 2024, par fritzHere is what I am trying to do :



WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.




This is what my SDP file looks like.



var cm_offer = "v=0\n" +
 "o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
 "s=nginx\n" +
 "c=IN IP4 127.0.0.1\n" +
 "t=0 0\n" +
 "m=audio 60820 RTP/AVP 0\n" +
 "a=rtpmap:0 PCMU/8000\n" +
 "a=recvonly\n" +
 "m=video 59618 RTP/AVP 101\n" +
 "a=rtpmap:101 H264/90000\n" +
 "a=recvonly\n";




What's happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :



ubuntu@ip-132-31-40-100:~$ ffmpeg -i udp://127.0.0.1:59618 -vcodec copy stream.mp4

All I get is a blinking cursor and The stream.mp4 file is not written to disk after I exit (ctrl+c).



So can you help me figure out :



- 

- why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
- How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn't send an answer back.







Here is the entire code (hello world tutorial modified)
