Thanks for the leads, George.
How do you envisage one would go about making an application's output
appear to the system that it is a camera? Any idea what protocols
determine 'this is a camera data-stream'?

If Ustream is looking for a "camera" input, you'd have your app or
some QC plugin setup so that it looks like a camera driver to the
system.
There are some opensource projects that use macam or fakam to do
that (https://github.com/rsodre/ofxFakam , or "Synapse")... I think
I've seen some sample code at the ADC that does something like that
as well, but I'm not 100% sure, can't recall any project names. I
have the impression that the app camtwist has that function, as far
as already available apps go. Again, don't use it, so I'm not 100%
certain about that.

Hi Rick and list
I'm wondering how you managed to feed a *non-camera* source into
Ustream for webcasting. I just created a Ustream free account and
it's pretty effortless to get a camera feed broadcasting (using the
dropdown Camera menu) but I can't see an obvious way to feed it
vision from a live production tool or pre-recorded media.
I'd like broadcast seminars with live audiences by vision switching
between:
i live camera (speaker) with bottom third overlays (say done with
QC),
ii Skype video feed (when presenter is remote from the live audience)
iii The presenters PPT/KN slides
iv Pre-recorded videos
v Branded ID slides
All while the audio of the speaker streams (whether she is in
person or streaming to the seminar via Skype)
So wondering firstly how you are getting the video feed into
UStream that includes your post-production pipeline of QC
compositions and secondly what live streaming solutions list
members have used that would incorporate the sorts of things I'm
looking to do here.
Wondering if Syphon could be used in conjunction with some sort of
streaming app to get me where I want to be, ie. QC magic + live
video + skype?
Another tool I'm considering is Adobe Connect since I've sat-in on
quite a few Adobe training seminars and it seems reasonably robust
accept for occassional sound drop-outs but they use a 1300 number
as backup. Not sure on the production limitations Connect has, I
don't recall seeing live video but not sure if it's strictly a
screen-cast-only technology (workaround would be to put a video
window on the desktop and screen cast it I guess). It can switch
broadcast to PDF slides and perform audience polls (Ustream can do
polls it would seem).

If you like space, especially Space Shuttle launches, I recommend
you check out the QC overlay I did for Spacevidcast:
http://spacevidcast.com/live/
A few days before launch (the next Shuttle launch is Apr. 29), you
can see a real-time countdown displayed across the bottom of the
screen.
The composition I created uses a QC plug-in I created that is
based off an iPhone app I created called MissionClock (http://bit.ly/missionclock
). It shows countdown holds, real time left to launch, rapidly-
updating ascent statistics, and possibly this time, countdown
events (if I have time before launch).
The graphics slide in and out, change color, and update
automatically based on the current state of the count.

Hey Guys,
For anyone living in the UK, check out Channel 32 on Freeview
from 6pm tonight. We've implemented a new playout system
developed by Tools On Air which utilises Quartz Compositions to
overlay graphics.
I created a few quartz compositions for the channel, they aren't
that intense, but do make good use of the ability to pull
information from a database via xml imports. It's always nice to
see Quartz in the wild! If anyone else on the list has examples
of Quartz in the wild I'd love to have a look at it.
Peace,
Charlie
