Keeping control of your media in your hands
13 avril 2011, parThe vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".
MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.
MediaSPIP aims to be accessible to as many people as possible and development is based on expanding the (...) -

RTP packets detected as UDP
28 février 2017, par user3172852Here 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

libpostproc 54. 2.100 / 54. 2.100All 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)

Android plugin with .so lib's (UNITY)
23 mars 2017, par Vladimir IlianovSo i need ffmpeg in android. (for muxing audio and video).
I found this awesome project for android studio (link in the end of a post, in rar as ffmpeg4android_demo_studio2).
I works perfect, does muxing and overall awesome project. So i decided to make plugin for anroid from that project, so i remade project like that : (link in the end of a post, in rar as ffmpeg4android_demo_studio ((p.S. the is no GeneralUtils code because its big, please download rar and open it.))package com.netcompss.ffmpeg4android;

When i launch apk made from original project in AndroidStudio everything works fine.
When i launch apk made in unity its works fine until this part :
