Hi List,
I'm making a media installation. One screen shows video streams from
several
webcams in the world, another screen shows you watching these streams.
Basically i have two issues that I need to solve. One caused by the
install
(or something I did wrong during that process)
To make my Microsoft Lifecam Cinema HD (not really a fan of MS, but
that's
what i got) stream live video I installed the dev version of uvc-video.
After I booted my PC this morning unfortunatly vloopback stopped working.
The other issue I could ask in a separate email, basically i can record
the
webcam output, but not stream it.
Thanks,
Bart
Some outputs according vloopback (the suggestions I found elsewhere to
just
reboot don't work):

I love deadlines. I like the whooshing sound they make as they fly by.
