hi im using hp dv1301tx , my webcam cant work with photobooth!!
is there a way? i tried maccam ,camtwist but it does not work!!

thanks!


Did you try manycam? AM I the only one manycam has worked for?

Seems astonishing. Well I dont have much to add to this. I am not a programmer and the solution we need would have to come from someone who can program a app that can force up and down the res to make it work in OSX. Thats basicly what manycam does for my camera.

I tried all the cam solutions here - none of them worked for my acer crystal eye (which is a Suyin).
tonite I tested the IOUSBFamily.kext provided in this topic http://www.insanelym...howtopic=215338

et voilà - webcam working with all apps - no more patchin needed :D

never thought about an USB solution for that problem...... crazy

EDIT: it was not a real solution - the IOUSBFamily.kext made the camera work but slowed down to USB 1.0 with 12 Mb/s :)

that means USB 2.0 480 Mb/s not working
with USB 1.0 with 12 Mb/s it works

that could be a hint to the right solution. is the slower rate affecting resolution?

I have a MSI Wind U123 netbook with a built in webcam: BisonCam, NB Pro. Photobooth, Skype, Facebook webcam doesn't work for me, but iChat, Gmail Video chat works fine.

I went to System Profiler, and my webcam is detected and the following info shows:

BisonCam, NB Pro:
Product ID: 0x0203
Vendor ID: 0x5986
Version: 3.08
Speed: Up to 480 Mb/sec
Manufacture: Bison Electronics Inc.
Location id: 0xfd500000
Current Available (mA): 500
Current Required (mA) 500

I tried maccam, manycam but they didn't work.

I was reading through this topic and noticed that linux has support but is there any way to port that into OS X?

The problem depends on the graphic drivers, people :

I have a Toshiba Satellite L500-120 ( german/european ) model with built-in Chiconey 1.3 MP cam.

Nothing webcamwise so far works, no matter if under 10.6.x or 10.5.8.

Because I have a unsupported Ati HD46xx gpu I must use dong's great Framebuffer driver RadeonHD.kext for full resolution on my Laptop ( works fine ) . This driver gives 2D basics, but no QE/CI, in other words no OpenGL/3D.

I fear that this is a factor to consider why some of us can get webcams to work and others not. Many of the built-in Apple applications like Photobooth wont work without OpenGL ( QE/CI ), they use it for the "Quartz composer" effects which a 2D driver simply can not deliver ( or only via software rendering, but that seems to be blocked by the apps ).

So we need to dig a bit deeper into webcam support and how it depends on 3D. I guess in Leopard 10.5.x its a bit easier as in Snow 10.6.x, because Snow has OpenGl now even in everyday apps like preview.app and grab.app ( which I can not use with the RadeonHD.kext - therefore 10.5.8 is better for me ) -

As someone said that Tiger 10.4.x had support for more cams I can think that this is true also. Tiger had no need for QE/CI, it could run on any graphics card. ( I had it running on a imac G3 333Mhz with a crappy 16mb ati card and Tiger ran beautiful on that old mac. That hardware windows-like would not even allow xp in its full glory )

Apple slowly adjusts OSX to be totally 3d aware - started in Tiger as an option, in LEopard a bit more and in Snow it is essential. Ichat in 10.6.x makes also use of same effects that photobooth uses..

This needs to be thought of. :censored2:

I have a Logitech C910 HD webcam.

It is detected, microphone is working, but screen on any video capture program is black.

It does work with QuickTime to capture video on Medium picture setting but it is totally unusably. (worse than a slide show).

I haven't tested on many apps but it does work PERFECTLY! with Apple's Facetime beta. But what I did notice when using with Facetime is that... it must be GPU accelerated as I can hear the fan spin up when using Facetime.(beta)

So what is special about Facetime that it works? Maybe it is program based ?

Latest Skype 5.0 beta does not work either.

Damn, C910 doesn't work with Skype?

What about the non-beta? Would you be kind enough to try Google Voice/Video chat? That is what I use mainly.

Interesting.. It makes sense but in 10.5 I was using a hacked framebuffer for my x3100 to make the mac x3100 kext work (full QE/CI) and then I deleted the UVC driver and got full use of my cam as if it was a mac cam, no restrictions.

In 10.6 it did all change but I am completely vanilla in 10.6 with all apple x3100 (full QE/CI) support via DSDT. When I deleted the UVC driver or make alterations it just makes my cam not start at all. Then I found manycam and it seems to correct the problem. I think some people might have cam problems related to video kext but its not my problem.

Interesting thoughts though.. Id still love to find a UVC edit for 10.6 to make that driver support my cam fully without manycam. I know thats gotta be possible as that driver is the main thing that starts your cam.

Ended up getting a c910 a while ago. Works perfectly with skype/gmail/facetime. Great quality, though can't take advatange of the HD. Autofocus works great since it's built into the firmware.

Sorry to bring back a very old topic - but I'm wondering if anyone has a solution to my webcam problem.

I have a Lenovo Thinkpad T61 running Lion 10.7.5 with a Lenovo branded (showing as Chicony) webcam. If I launch an app that uses the webcam, all i see is a black/blank screen. For example, the Facetime app doesn't load at all.

I've read all 9 pages of this thread and all the early solutions didn't work for me (kexts, CamTwist, etc.). Finally, one of the last solutions recommended by a member here worked for me: Manycam. When I run Manycam, the app is able to initiate the camera successfully. Then, if I open up a native OSX app (Photobooth, Facetime) it works! It's as if it needs Manycam to "initiate" the video, and then it is able to pick it up in the other apps. Note that this workaround didn't work for Skype unfortunately.

Does anyone have a real, native solution to this problem of mine? This is the last thing I need to get my hackbook working 100%. For now, I'm just going to use this workaround, but I was wondering if anyone out there had the same problem as what I described and found a working solution.

Thanks.
