Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

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 :

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)
