quicktime 7 on pc with webcam (Read 19760 times)
quicktime 7 on pc with webcam
Nov 1st, 2005, 10:30am
 
So I've read all the bug reports on quicktime 7 and everything.  But I'm still having some issues with quicktime 7 i'm fighting with.  I got java running fine, (which was problematic when i tried to uninstall quicktime 7 and install 6.5, it screwed up processing so the point where it wouldn't run anything) but with a help from casey, i got it to run again on 7 but still if i input with a webcam, i get this

a pop up message saying:

0Logitech QuickCam Messenger-WDM : Problem connecting Video Output to Video Renderer

and processing saying:

java.lang.NullPointerException
at processing.core.PGraphics.image(PGraphics.java:1628)
at processing.core.PApplet.image(PApplet.java:6064)
at Temporary_7075_2084.draw(Temporary blah blah blah

any suggestions or should i just go back to 6.5?  I know the problem with the expired qtjava on the apple side but i also received the same error on the pc side.  

as for video, i checked the webcam, it works, i used windig to check the video feed, that works too.

if anyone could shed some light or just give me a nudge to give up and go back to 6.5, it would be much appreciated.

have you upgraded to winvdig 1.05? another poster seemed to say that it was the problem and that 1.01 was ok even with qt7.

I had the same problem after installing winvdig 1.05.

I moved back to winvdig 1.01 and everything works.

I confirm that moving to the old version of winvdig is working. I changed my config to QT6.5 & WinVDIG 1.01.
Everything's ok.

i have a similar problem with quicktime7.0.3&winvdig (qtcap version 1.0.1) on winxp sp2.

i can capture using other (directshow-based) applications, however both on qtcap and processing, i have the following error:

"0A4 Tech USB PC Camera-WDM: Problem Connecting Video Output to QuickTime"

i tried to uninstall and reinstall quicktime (just quicktime, not the whole itunes thing) but still have the same problem..

please heeelp Sad

oh i'm also using the quickcam pro 4000, could be similar issue to the other guy, xp, sp2, qtjava with 7.0.3,  the message i assume he's refering to is the message i get that the video output could not connect to the video renderer, is the video output qtcap and the render processing?

another weird thing, based on my previous post, i thought, hey maybe opengl mode will work (i don't think i ever tested opengl with video so i might be repeating some really ancient post but)

here's my code


import processing.opengl.*;
import processing.video.*;

Capture camera;

void setup()
{
 size(200, 200, OPENGL);
}

void captureEvent(Capture camera)
{
camera.read();
}

void draw()
{
image(camera, 0, 0);
}


here's the error message ,it's different from the previous ones i've gotten, no pop up about connection, just....

interesting developments:

ok, i'm up to 99, so the strokecap is fixed, but the webcam problem still presists.

what i have found interesting is, vdig is not 100% resolved, the error i get from processing (the video renderer not communicating with the output)  is also in vidg (just not apparently first off.  if i go to video settings and change it to source, i get the same message popping up.  

http://users.design.ucla.edu/~djaiyo/p5webcamissue.jpg

any ideas? i'm gonna do a roll back to winvdig .99  i'm on 1.01 right now....  i'm close to formating the damn computer and rolling everything back a few generations...

just to recap, I fixed the problem and it seems my system, for some reason, capture.list() doesn't work and you can't specifically call a camera.

so if you have

video = new Capture(this, , "name of camera", video_width, video_height, 30);

and it doesn't work, try:

video = new Capture(this, video_width, video_height, 30);

instead

p.s. i was running winvdig 1.01, processing 99. windows xp, quicktime 7.0.4


good luck to ya'll

Hi
I am running latest xp pro, latest qt7 and couldnt get video to work in processing.
So I upgraded from vdig 1.01 to 1.05 and the video went all screwy - pixelated and split into red half and green half with warning about not connecting. So I rolled back to vdig 1.01 but the problem stayed the same.
I have tried reinstalling QT and vdig with no joy.
I use vdig+QT a lot in other apps so any help in how to fix this much appreciated.
Thanks

Update
I deleted the files vsVDIG from system32/quicktime AND program files/quicktime and deleted VSdump from system32- uninstalled vdig - reinstalled vdig 1.01 and things seem to be working now - even processing which wasnt connecting before - wtf is that all about?
