Redirect listeners and fallback

Hi Folks

First of all, excuse my bad english.
I'm working in the video streaming team of the next WikiMania, the
conference of the Wikimedia fundation, this year in Buenos Aires.
We are facing some issues with some specific features, the setup we are
thinking of is the classical dvgrab | ffmpeg2theora | oggwd *

It all works fine, but we need to use fallback or move listeners,
because we have 2 different sources locations (separated by 200m, with
different internet links) which are not used simultaneously (one is for
key notes only), so we would like to transfer the listeners from the
secondary to the key note and back when it's over. We would like to be
able to move the listeners to a mountpoint showing "brb" at the cofee
breaks.

We have tried using the fallback option, the clients (sometimes) goes to
the fallback mount point, but it never comes back when the stream is
reconnected.
We also tried moving "by hand" using moveclients.xsl, in that case the
player freezes complaining it's a broken stream (tried mplayer, vlc and
totem).

This issues happen both with the stock icecast from debian and ubuntu
and with the last kh branch.


Please let me know if I should clarify any point or add aditional
information.

Thanks in advance.

Ariel.


*It's actually a little bit more complex, we connect to a local icecast
at the source and then wget|oggwd that to the real server, so we can
have atendees watching the streaming without consuming the internet link
bw. Also, we are using several icecast servers to balance the load, but
none of these has anything to do with the issues mentioned.

Errata:

Where it says oggwd should say oggfwd.
And algo a note: all the mounpoints and fallback have the same a/v
configuration (size, fps, etc)
