Play RTMP stream from command-line

Question

I've managed to get flvstreamer to read a radio station's RTMP stream with the options --live -r [url], and it outputs what I guess is the raw audio data + stream info to stdout.

Can I make it play the stream through my speakers, from the command-line?

Possibly by sending sending the raw audio data to mplayer or something else. Thanks.

I got it to work with the command ./flvstreamer_x86 --live --quiet -r [url] --buffer 3000 | mplayer -vo null -, but it quits after a couple of seconds to a couple of minutes. I added --buffer 3000 to imitate what I saw when tracing the original Flash player with Wireshark. These are the last rows of output.

This was with flvstreamer 1.81. I couldn't get it to work with any version above, they just output

How can I make it play continuously? Thanks.

I think I've made it work with 1.81 now :)

./flvstreamer_x86 --live --quiet --buffer 3000 -r [url] | mplayer -vo null -idle -

I added the -idle to stop it from exiting, I guess the problem was that flvstreamer needed to buffer and mplayer didn't receive more data, so it quit.
