[Red5devs] Request for help

Sun Feb 15 19:43:38 PST 2009

That's what I'm suggesting; I'll put the audiotranscoder and videotranscoder
demos that ship with Xuggle's Red5 adapter into our demo app installer (as
WAR files), and then folks can install them IF they've also installed
Xuggle.

The reason to add xuggle-xuggler.jar to $RED5_HOME/lib is so that folks
DON'T have to copy it themselves.  So far, this step has confounded a bunch
of users on the xuggler-users group; they expect:
1) install xuggler
2) install red5
to just work.  Just "documenting" the approach hasn't been working -- it's
documented on our web-page but people constantly miss or skip the step.

So, if I put the audiotranscoder and videotranscoder demos into the Red5
installers folks can easily see it working if they've got xuggle installed
(and the apps won't be in the red5 trunk, so won't break anyone who hasn't
installed xuggler).
