You can do that yourself. rtmpdump | tee /tmp/somefile | whatever. Learn how 
to use your computer before you make stupid feature requests.

I've spent a lot of effort writing glue code so that apps like mplayer, 
ffmpeg, VLC, and XBMC can all integrate directly with librtmp. If viewing 
media just by running rtmpdump and spitting data to stdout worked reliably, 
there would be no need to jump in at a lower level (library integration).

But the fact is, an RTMP stream is a complex beast; it's a 2-way conversation 
between a client and a server. Piping output from rtmpdump to some other 
program is only 1-way communication; much flexibility is lost doing this.

Now please quit asking the same questions over and over again.
