kind of tricky, but it maybe possible, you need:

ffmpeg built with rtmpdump
adobe flash server (or wowza or other rtmp server)


run ffmpeg with all of the options required for the stream to work, e.g.
ffmpeg -i "rtmpe://... swfurl=blah pageurl=xxx app=yyy"

then output it to your flash server using: -c copy -f flv rtmp://serverip/app/streamName

or if you just want a simple, non-streaming playback in flash player, you can have ffmpeg output to an .mp4 file and create some simple flash embed html to open your .mp4 file on a webserver.
