[PD] [pix_video] multiple webcams at once on macbook
I have two webcams, internal and external. [pix_video] detects only one webcam, and it grabs always external one, but very very occasionally the internal one.(I can't choose it) Using multiple webcams works on Linux, but not on macbook.

Re: [PD] Pix_video
Yes, that's why i was talking about "recent macs's built in webcam driver", (possibly models with PCIe-based cameras such as the MacBook Air 2013, and others since), and by "macs" i DONT mean "non-apple hardware" :) QuickTime API (which is used by GEM for video capture) has been deprecated since 10.9, so it can be presumed that full compatibility with this obsolete video library was not Apple's priority for their new webcam drivers (which already had their problems on OSX 10.8 before a bug fix update : http://www.macrumors.com/2013/09/24/os-x-10-8-5-supplemental-update-being-prepared-to-address-facetime-camera-and-other-issues/ ).

Just want to share this: I am working on OSX 10.9.5 with pdX-43.4 as well and i DONT have any problems getting my webcam running (built in and USB). This applies to my Desktop as well as my laptop. The interesting part here is, that i am running OSX on non-apple hardware. So maybe the bug is related to the apple-machines themselves??? regards, Peter Am 12.04.15 um 00:52 schrieb Nicolas Lhommet: Hello, It's probably the same problem, related to recent macs's built in webcam driver incompatibility with the video library used by Gem, that has been discussed last month on this list, and for which i proposed a workaround : make use of "iGlasses" shareware as a "webcam passthrough" (see "GEM Motion Capture" thread for details), but a real solution will require a rewrite of Mac OS X video-related code in Gem.
