[Red5devs] Request for help

[Art Clarke]

While I like that idea, it's got a problem -- Xuggler won't work unless you
also install the native component on your machine.  Putting in the
$RED5_HOME/lib directory makes things easier for those who want to use
Xuggler with red5, but should cause no harm to those who don't use Xuggler.
If I also add code to Red5 that requires com.xuggle, well, you see the
problem: I don't think we want to force red5 users to install xuggler (and
I'm even very biased towards xuggler).

The order would be:
- install Xuggler on your server
- install red5
- write code

That said, I'm happy to create a WAR version of the xuggler red5 demo (the
thing with the weird mirror effect) as a compromise -- complete with source
code.  We could even put that into our installer's war packages...

That particular piece of source code actually does on-the-fly conversion and
bit-rate conversion, and loads more (see com.xuggle.red5.Transcoder).  And
we've already published it.  What do you think?
