[Swfdec] client command-line or library for streaming audio and video - does it exist?

[Luke Kenneth Casson Leighton]

folks, hi,
this message goes out to all the relevant mailing lists.
for streaming audio and video, critical to performing inter-red5-server transfers, 
and integration into other free software projects, and critical to the
development of gnash and swf-dec is the existence of a command-line client
and/or library for uploading (and downloading) AMF-formatted streams to and
from a flash media server such as red5.
does such a client - or library - exist, that anyone knows of, in any language -
c, java or python?
for example it should be really trivial to write a plugin for kopete or
gaim / pidgin to utilise red5 (or rtmpy when it's ready) as a audio-video
media server.  this would be a first big step to adding webcam support
to gnash and swf-dec.
the reason why i am asking is because i would like to see some integration
of real-time audio broadcasting into some of the "music production" software
for linux.  so, whilst someone is doing a live performance (dj or broadcaster)
their production is going out real-time onto a red5 or rtmpy server.
