I don't know what I want, maybe because I'm new to video. So I hope to play around and get some ideas. But right now, for my first idea, I need to translate something on a videofeed into OSC messages + project the video (maybe with some simple explanatory overlay for the audience to better understand what's happening) with a projector. I have som starting ideas about what that something might be. Something like how red is the picture, from 0-1, how much activity is in the image, from 0-1. My system, currently implemented in ChucK is easy to configure to do something useful with these messages. -- peace, love harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] getting started with webcam/pdp
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: [EMAIL PROTECTED]:~$ pd tk scaling is 1.18830409357 init : Avifile RELEASE-0.7.47-070916-12:47-4.1.3 init : Available CPU flags: fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe up bts est tm2 init : 1600.00 MHz Intel(R) Pentium(R) M processor 1600MHz detected X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 143 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 32 Current serial number in output stream: 32 socket receive error: Connection reset by peer (104) 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).

You could pull out the pidip.pd_linux and use it with a different version of Pd-extended. It would also be possible for Yves to distribute the new objects on their own, and single files per objectclass.
