Hi
I run linux (ubuntu 7.10) and pd-extended installed from
Pd-0.39.3-extended-debian-testing-i386.deb
I have some experience with pd, but none with video. I hooked up my
phillips webcam and dmesg tels me it's connected to /dev/video0. Skype
shows video from this device just fine.
However I can't get it going in pd. I tried running the
examples/pdp/input_output.pd patch, and I briefly see a black window,
then pd dies with this in the terminal:
atte at ajstrup:~$ pd
tk scaling is 1.18830409357

Am I on the right track? I want to grab some video from the cam, and
based on "something" in the image send out OSC. I don't know what
"something" is yet, need to play with it, but I have the idea of the
audience influence the music (which is running in ChucK). Am I still on
the right track?
