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. -gt On Apr 5, 2012, at 12:56 AM, Alastair Leith wrote: > Hi Rick and list > > I'm wondering how you managed to feed a *non-camera* source into Ustream for > webcasting.
