Multiple Webcams and Macam
Oct 8th, 2009, 7:53am
 
Hi Everyone,

I'm new to the world of webcams. I want to use several webcams on one computer to use for some analysis and playback on a screen. A lot of webcams have crappy drivers. Windows can't handle webcams of the same kind (it gets confused with drivers). Using macam on a mac processing complaints about a missing NSAutoreleasePool which means autoreleased objects are leaking:

2009-10-08 16:17:57.016 java[2077:1ae0b] *** _NSAutoreleaseNoPool(): Object 0x1cb090 of class NSThread autoreleased with no pool in place - just leaking
Stack: (0x936fcdac 0x93629e14 0x9362f3e0 0x1243bf14 0x12440e60 0x1243f5a4 0x12443958 0x124425e0 0x948fc7d0 0x947dabe4 0x948ff648 0x947e2530 0x948fd860 0x947c86d4 0x947cdb08 0x94e37590 0x35a0bac 0x35989f0 0x3598ab0 0x3598e10 0x3596164 0x4c6e88 0x410174 0x410060 0x40fff0 0x40feac 0x69b034 0x918771d4)



When I close the applet I get several messages like:

2009-10-08 16:20:15.252 java[2077:1c503] *** -[NSLock unlock]: lock (<NSLock: 0x1e6570> '(null)') unlocked from thread which did not lock it
2009-10-08 16:20:15.256 java[2077:1c503] *** Break on _NSLockError() to debug.

Does somebody have a solution to these messages?

I'm sure some of you walked the same path, so I also would like to ask if you guys have some suggestions which webcams work well on both mac and windows. Or any other recommendations that comes to mind working with webcams and processing.

Thanks for any pointers,

regards,

Jorn
