When you say a "live mpeg4 stream" what sort of device is this coming from
to begin with? If it's a camera, then that can be broadcast in much the
same way that the Video Conference demo (fitcDemo) works - the incoming
video and audio are encoded into an FLV format, which you can save and/or
stream on the fly.
Otherwise, if what you mean by "live" as an existing file - in your case
in the mpeg4 format - then you'll have to encode that into the FLV format
before it can be streamed through Red5. Depending on the duration and the
desired quality and pixel dimensions, these things take time to convert
and generally what you get by doing this "on the fly" is not going to be
as visually appealing as taking the time to encode the file properly.
It might be helpful to know more about what you'd like to do so that we
can suggest how to best accomplish it - or let you know what can and
cannot be done at the moment. :)
