Multiple USB Mac OSX Webcam
Can anyone recommend?
1. A mac osx compatible webcam (reasonable quality)
2. How to connect multiple USB webcams to a mac with Jitter
3. How or if Max/Jitter will enable me to access all cameras simultaneously in realtime.
I assume the jit.qtgrab object is the way forward here, but don’t know how to get at least two working at once. Any help would be much appreciated.
this person claims to have 3 working webcams with jitter.
what have you tried?
i think this issue has been discussed many times before on this forum. Hear is the link to the AndrewBenson tutorial ( http://www.cycling74.com/story/2009/10/26/153715/40 ) that i recommend you to read.
Hi. First of all I recommend you to use this Universal Driver for playing every existing webcam : http://webcam-osx.sourceforge.net/
It works seriously.
Then, use the following patch and you should be able to see your two or three webcams as a devices in vdevice list by pushing "getvdevlist". It’s pretty simple.

very useful info. I had seen the video tutorial but it didn’t really answer the specific question I had.
I had already installed the Macam software, but it seems to work as a standalone application. I assume it’s loaded in a bunch of drivers for generic use too? Also (eeeee.), how do I get that code you sent into Max?
So,what if I wanted to connect a few of these using Vers 5 in Mac osx?
If you hadn’t guessed, I’m a newbie, so any help is good. cheers.

How to put that code into a Max patch? Simply you have to copy-paste it (from ———-begin_max5_patcher———- to
———-end_max5_patcher———–) into a new Max Patcher

Forget the standalone Macam. The most important thing to do is to replace the "macam.component" in /Library/QuickTime/ for using every cameras with other applications (like MaxMsp) .
Dont forget an Usb Hub for plug in your several webcams.
This post seems to contain a broken pasted patch. This can happen if you don’t copy the entire "———-begin_max5_patcher———-" or "———–end_max5_patcher———–" for each and every patch you paste; perhaps you missed a preceding or trailing "-" when you copied the patch? Please notify the Cycling 74 web team if you think it is a bug.
I guess you are refering to my post.
I used the Unibrain firewire cameras.
haven’t tried with usb
I connected my cameras to a firewire hub.
2 of them were chained and plugged to the firewire hub
the third one plugged to the hub
One of the Unibrain advantage is that each cameras has 2 firewire ports so you can chain them easyly. You can also get b&w or color cameras. And there is a setting app for the color and gamma correction.
Hi thanks all,
I have issues though.
I have used the patcher you (eee.) suggested and although it always seems to work with and detect my iSight camera it won’t recognise the two MS VX-3000 cameras.
The set list in the patch doesn’t ammend or allow input from anything but iSight.
Even before this stage, having installed Macam and put the component part in the Quicktime library (as suggested) the only way the camera LED lights switch on (thus showing they are connected) is by first using them in the Macam program itself. Not what I’m after at all.
So, is this a Snow Leopard thing? a Macam QT component issue?
Is an MS webcam a no no with the above? Is the patcher an issue?
Also, I’d love to know what’s happening here in terms of how this process with external camera inputs works as I want to add/connect some non proprietry CMOS IR Cameras such as..
The thinking is, if it’s a hassle doing it this way with standard wecams how will it fair with other bits of kit on a Mac / OSX etc???
Let me know, cheers
Have you connected your cameras to a Usb Hub like eee is suggesting ?
With several cam, I would guess it is the same then with firewire, you would need a self-powered hub. The computer by itself doesn’t have enough electrical "juice" to power for that many cams at the same time.
we are trying to connect 2 Macally cameras via a USB-HUB (powered by an adapter) to the computer, and import the 2 different cameras in Max/Jitter. jit.qt.grab detects three input possibilities, iSight, Macally Camera and Macally Camera #2. Still, it only manages to select one of the external cameras. When selecting the second one it does not respond, although it is able to work with iSight and 1 external camera through USB HUB. Any ideas?
to copy the code , plz follow the following steps:
To copy this code into Max/MSP, copy (ctr+C) all the code that is in the gray box. In Max/MSP, go File >> New From Clipboard and it will paste the patch for you.
Dude, that was a year ago and someone already told them how…
