Very first attempts at geting a Phillips webcam working with PDP aren't going so well yet. OS = Gentoo, 2.6.4-ck kernel. The cam is using these modules: bash-2.05b# lsmod Module Size Used by <snip> pwc 49840 1 videodev 7936 2 pwc <snip> bash-2.05b# lsof | grep video pd 7220 root mem CHR 81,0 1315 /dev/v4l/video0 pd 7337 root mem CHR 81,0 1315 /dev/v4l/video0 pd 7338 root mem CHR 81,0 1315 /dev/v4l/video0 Anybody have some insight into the following error? pdp_v4l: opening /dev/video0 pdp_v4l: cap: name Philips 740 webcam type 1 channels 1 maxw 352 maxh 288 minw 160 minh 120 pdp_v4l: picture: brightness 32256 depth 24 palette 15 pdp_v4l: channel 0 name Webcam type 2 flags 0 pdp_v4l: switched to channel 0 pdp_v4l: buffer size 304128, frames 2, offset 0 152064 pdp_v4l: VIDIOCMCAPTURE: format not supported: Invalid argument pdp_v4l: no device opened pdp_v4l: attempting auto open pdp_v4l: opening /dev/video0 pdp_v4l: error: Maybe I should recompile PDP with explicit phillips webcam support? TIA, d.

thats what I mean too...! ;) It must be a signal object, and the object [scope~] is listed in the sickle part on the site http://suita.chopin.edu.pl/~czaja/miXed/externs/cyclone.html Matt -=-=-=-=-=-=-=-=-=-=-=-=- http://www.loopit.org/ -=-=-=-=-=-=-=-=-=-=-=-=- ----- Original Message ----- From: "Patrick Pagano" <bigswift(a)ufl.edu> To: "matthew jones" <m.jones(a)signal.dra.hmg.gb> Sent: Friday, April 16, 2004 1:09 PM Subject: Re: [PD] Oscilloscope/liassajous > i think he means Scope from cyclone > > On Friday, April 16, 2004, at 08:11 AM, matthew jones wrote: > > > can't seem to get scope~ doing anything. > > firstly pd complains that scope~ is now obsolete... maybe using an old > > alias > > for tabwrite~ or something? > > > > secondly it has only one inlet, meaning max help is not much (help), > > and > > drawstyle messages are rejected. > > anyone have any ideas?

gem_extracting_movement
by arana frederik 16 Apr '04

16 Apr '04

good morning everybody, i would like to make a patch using gem and the goal is to extract live cam to ineract with 3d_objects created in Gem, so i planned to use pix_movement but i don't see how i can and ----- what kind off data i could get from it? i imagine that i could create a dynamic form with all the properties off the movement (like particules)and apply it to the render scene.......but.... well i need a hand on this. thanks

gain normalization help?
by David Merrill 16 Apr '04

16 Apr '04

Hi there - I'm buildng a patch that features a chain of DSP operators being applied to a signal (volume, sweeping bandpass filter, tremolo, delay, etc..) and something that I've realized about the bandpass filter is that it affects the overall volume of the sound (even when the signal coming through has most - but not all - of its spectal energy at the center frequency) - which makes sense. I want to be able to switch the bandpass on and off, but keep the overall gain of the mix constant. Is there a preferred, canonical way to normalize gain and keep it relatively constant? (maybe something involving an env~ object..) thanks, David M.

pd running fully behind other windows???
by Adrian deCleir 15 Apr '04

15 Apr '04

Hi, I was just wondering, is there any way of making pd run fully behind other windows, as in the midi messages work perfect, but when I want to use the 'key' object a pd window has to be in front of all the other windows, this makes the Gripd program useless for me as I like to be able to use a computer keyboard for music as well a midi keyboard for my project cheers for the help, and thanks for all other help too by the way ,college is coming to an end and it could be the end of pd for me : (
