There have been lots of topics on this subject..
We've implemented a solution for dumping here.
mplayer to dump any stream to a file,
then use ffmpeg to encode to flv
afterwards you can easily stream the flv file.
#!/bin/bash
# © Camillo Bruni 2007
# [EMAIL PROTECTED]
# first param
if [[ $# -lt 2 || $# -gt 4 ]]
then
echo "usage:";
echo " streamDump.sh \$stream \$outputfile [\$recordtime] [\
$evalEndScript]";
exit 0;
fi
TMP_DIR=/tmp/record;
RECORD_TIME=30;
if [ -n "$3" ]
then
RECORD_TIME=$3;
fi
PID=0;
mkdir -p $TMP_DIR;
dumpfile=`mktemp /tmp/record/tmprecord.XXXXXX` || exit 1;
# if the stream ends with .mjpg attach that name to the tmpname
# because ffmpeg has some troubles to recognize the right filetype
filend=`expr //$1 : '.*\.\(.*\)'`;
/usr/local/bin/mplayer -dumpstream $1 -dumpfile $dumpfile &
PID=$!;
sleep 1; #startup time for the mplayer
sleep $RECORD_TIME;
kill $PID;
#append the filending otherwise ffmpeg doesnt recognize the filetype
mv $dumpfile $dumpfile.$filend;
dumpfile=$dumpfile.$filend
# convert to destination
/usr/local/bin/ffmpeg -i $dumpfile $2;
rm $dumpfile;
# evaluate the last argument as a command line script;
if [ -n "$4" ]
then
eval $4;
fi

Men,
the solution is really simple and works also for live streams, just
use BitmapData and draw method in Flex.
There is a limitation connected with this issue. You can't draw
BitmapData from RTMP stream, but ...
... you have to dettach NetStream from Video instance. Use this
trick on client (Flex):
video.attachNetStream(null);
// HERE DRAW BITMAPDATA - find some tutorial for this on net, be
sure, you are drawing "video" instance.
//
video.attachNetStream(yourStream);
and your stream will also flow on.
Good Luck.

The ffmpeg is working perfect when you have a flv file saved in the
server.
But when I do a live stream I have no file on the server.
