Summary: [branch] RTMP support in Asterisk
Description:
I created a new branch that implements Adobe's RTMP (Real Time Media
Protocol).
It allows Asterisk to connect as a client to an RTMP media server like
Red5 or FMS (Flash Media Server), and then publish or receive media streams
from such server. I only tested the connection with Red5.
To install the branch, you'll need several libavcodec, included in FFMPEG
version 0.6. Be careful to configure FFMPEG's sources with the
--enable-shared option activated in the configure script.
Prior to install Asterisk, you need to have librtmp on your system.
librtmp is part of the rtmpdump program : http://rtmpdump.mplayerhq.hu/
To install it :
# wget http://rtmpdump.mplayerhq.hu/download/rtmpdump-2.2e.tar.gz [^]
# tar zxvf rtmpdump-2.2e.tar.gz
# cd rtmpdump-2.2e/
# make
# make install
To install Asterisk :
# svn co http://svn.digium.com/svn/asterisk/team/phsultan/rtmp-support
asterisk-rtmp
# cd asterisk-rtmp
# ./configure
# make menuselect
[check here that chan_rtmp is eligible for installation]
# make
# make install

OK, it's at least not ALWAYS crashing. :-)
I am connecting with Eyebeam 1.5.18.3 release 1104g build 54685 on the
Mac. The Asterisk system and my SIP softclient are on the same NAT'ed
network, so they see each other directly (192.168.1.xxx) with no
translation in between. I am not using ICE or STUN.
I have patched ffmpeg as follows:
Info : in order for X-lite to accept the video stream, you will have
to patch your FFMPEG installation with the following hack :

;- download a file from ted.com stored in the RTMP server using rtmpdump
:

;- instruct to play the downloaded file from the dialplan :

This works for audio only. When I attempt to open the video tab on
Eyebeam, Asterisk crashes with a core dump. (core dump available if you
want to see it)
