converting UDP RTP to RTMP

[Nikolay Epifanov]

Hi,

Can crtmpserver listen passively on some UDP port, receive UDP RTP
stream and convert it to RTMP stream (so client could connect and get
RTMP stream)?

If so, what should I put into configuration file to make crtmpserver
bind new stream to some name, so I could request this stream?

I've been asking the same question, but no-one seems to care/give ANY
suggestions.
My Case is to produce RTSP TCP:554 based stream from VLC's UDP RTP
output. Video is H264 & aac audio..
I just don't know that module to use in this server..

I am able to stream files from flvlive modules to rtsp...

I would like to have this feature too.

[C++ RTMP Server]

METHOD 1 WITH VLC:
1. Start VLC:
/Applications/VLC.app/Contents/MacOS/VLC -I dummy ~/work/crtmpserver-trunk/media/tbs.mp4 --sout='#rtp{dst=0.0.0.0,sdp=rtsp://0.0.0.0:2323/test.sdp}'

2. add the following external source inside crtmpserver config file
{
uri="rtsp://127.0.0.1:2323/test.sdp",
localStreamName="gigi"
},

3. Start the crtmpserver

4. You can now access the stream:
rtmp://localhost/live/gigi

METHOD 2 WITH ffmpeg:
1. Start the crtmpserver (it is already configure to listen on 6666 for inbound live FLV. Bare in mind: THIS IS NOT RTMP)

2. Start ffmpeg:
ffmpeg -i ~/work/crtmpserver-trunk/media/tbs.mp4 -acodec copy -vcodec copy -re -f flv -metadata streamName=gigi "tcp://localhost:6666"

3. You can now access the stream:
rtmp://localhost/live/gigi

Cheers,
Andrei

I tried method 1. Works great! However, feed from VLC needs to be
started before starting CRTMP Server. if feed was stopped and started
for some reason, then the server needs to be restarted. Is there a way
for the server to recover without restarting?

I was running iftop and see that incoming rate is about twice the
outgoing traffic. Does that mean RTSP uses twice the bandwidth than
RTP?

50.0Kb 100Kb 150Kb
200Kb 250Kb
└───────────────┴───────────────┴───────────────┴───────────────┴───────────────
host1.testonly.com => client ip address 103Kb 100Kb 99.4Kb
<= 200Kb
193Kb 192Kb

I have no idea how iftop works (nor I want to learn :) )

As a general rule, make sure you properly filter the traffic before measuring it. In RTSP you have either one connection (RTP over RTSP) or 2 or more connections (one TCP connection for RTSP and one UDP connection for each audio/video track inside sdp)

Also, I ***strongly*** suggest not to paste this kind of stuff here because it is badly formatted (I can't understand a thing because word wrap). Please use pastebin.com or a similar service
