Hello,

do all of Logitech UVC cameras support raw Bayer mode? If not, can we get the list of cameras supporting it? I'm especially interested in QuickCam® Pro 9000.

Thank you,
Paul.

Welcome to the Logitech QuickCam® Team Discussion Forums pauljurczak!

I think that all UVC cameras support this mode...per this FAQ -

http://www.quickcamteam.net/documentatio...ch-webcams

Hopefully mrubli can enlighten us further if this is not the case.

Thanks.

To be frank I haven't tested every one of them but it should work with all of them. I'm planning to do some more testing and then add the results to the FAQ.

Have you already tested the QC Pro 9000?

I didn't buy it yet. I'm going to, if raw Bayer is supported.

Hi Paul,

I've just run a test for the QuickCam Pro 9000 and as expected it supports raw streaming in Bayer mode. I've attached a few samples I took. There are YUY2 and 8-bit Bayer images for 920x720 and 1600x1200.

Two notes:

• I took the pictures in office lighting, not in the lab, so don't take the color chart too seriously.
• I didn't move the camera between the pictures, you can see the cropping mentioned in the how-to.
  

I will update the how-to document later with some more information. In particular I need to update the GUID because the location of the two relevant controls has changed in our latest camera generation.

Cheers,
Martin

Hi Martin,

Thanks a lot for checking it out! I'm going to order one of them now and maybe a few hundreds of them later, if everything works OK. I'm planning to test QuickCam Communicate STX p/n 961464-0403 (see my posts to Linux-uvc-devel). Please let me know, if you know for sure that it is not an UVC camera, otherwise, I'm willing to test it out.

Regards,
Paul.

Hi Paul,

I'll try to get a list together that links part numbers with USB PIDs. (I don't use the part numbers much in my work.) In the meantime I can confirm that PID 0992 is definitely a UVC device. 08D7, on the other hand, is not a UVC device.

Packaging P/N: 961464-0403

USB\VID_046D&PID_08D7 ; Sully, Logitech QuickCam Communicate STX
QuickCam 10.x/11.x

From the FAQ's posted over at the Users Discussion Forum, this STX is not UVC compliant.

FAQ Link - http://logitech-en-amr.custhelp.com/cgi-...w_search=1

Please note that there is no information posted about the QuickCam Communicate Deluxe (USB\VID_046D&PID_0992 ; Super Sulley 1.3).

Thanks.

@Martin -

09C2?

Thanks for the link, very useful! Unfortunately the list is indeed out of date, so I'll try to complete it and then combine the whole thing somewhere.

PS: I removed the obviously wrong part number from my post above in order not to create more confusion.

Whose list?

The FAQ is dated 10/08/2007 (not that it is entirely correct).

I try to maintain my own listings...since many of the older camera models are no longer mentioned in the FAQ.

I don't keep track of the 9xxxxx-series numbers because Logitech *seems* to use them over for different 8xxxxx-series numbers.

Never mind. Turns out I was victim to a copy/paste error in one of my reference lists. :-(

OK.

Wow, so many part numbers! Must have my Ibuprofen now! Does it mean that QuickCam Communicate Deluxe p/n 960-000169 (NewEgg) or 961465-0403 (Logitech US website), or 961465-0311 (Logitech Australia) has USB ID 046d:0992 and is an UVC device?

Packaging P/N: 961465-0403

This *appears* to be the QuickCam Communicate Deluxe (USB\VID_046D&PID_0992 ; Super Sulley 1.3)...which is UVC compliant.

Thanks.


(Ref: FAQ #6471)

Hi Paul,

Hope you recovered from your headache, I know I did. ;-) Sorry it took me a while but I think I finally have the information together.

960-000169: QuickCam Communicate Deluxe (latest model), VID 046D, PID 0992, UVC compliant, SPCA527 chip

961465-0403: QuickCam Communicate Deluxe (older model, U.S. market), VID 046D, PID 08C8, Vendor-class (but works with the Linux UVC driver), SPCA525 chip (Update: This information is probably wrong.)

961465-0311: QuickCam Communicate Deluxe (older model, Asia/Pacific region), VID 046D, PID 08C8, Vendor-class (but works with the Linux UVC driver), SPCA525 chip (Update: This information is probably wrong.)

Whatever the part number, PID 0992 is always UVC compatible, PID 08C8 is not.

Cheers,
Martin

Hi Martin,

Thank you for the research you did. I'm going to buy one of 960-000169. Can you make a correction in UVC webcams table at http://www.quickcamteam.net/hcl/linux/logitech-webcams and replace Communicate STX with Communicate Deluxe?

Regards,
Paul.

I do not have an 08C8 listing.

Done, thanks. I also removed the asterisk because the camera works fine on Linux. :-) Sorry for the confusion this created ...

I'm actually testing a Quickcam Pro 9000 (0046d:0990).
It does not seem to contain the XU1 extension unit so raw bayer
mode probably can't be enabled.

The actual list of entities seen by the driver is:

00000000-0000-0003-704a-de7d0081ffff (id 1) (name Camera 1).
40000001-0002-0000-304a-6c7f0081ffff (id 2) (name Processing 2).
63610682-5070-49ab-b8cc-b3855e8d221e (id 4) (name Extension 4).
63610682-5070-49ab-b8cc-b3855e8d221f (id 13) (name Extension 13).
63610682-5070-49ab-b8cc-b3855e8d2252 (id 10) (name Extension 10).
00000004-0000-0000-0000-000000000000 (id 5) (name Output 5).
63610682-5070-49ab-b8cc-b3855e8d2250 (id 12) (name Extension 12).
63610682-5070-49ab-b8cc-b3855e8d2251 (id 8) (name Extension 8).
63610682-5070-49ab-b8cc-b3855e8d2255 (id 11) (name Extension 11).
63610682-5070-49ab-b8cc-b3855e8d2256 (id 9) (name Extension 9).

XU1 would be 63610682-5070-49ab-b8cc-b3855e8d221d and is missing.

Sorry for the late response, somehow I didn't get the notification for your last message and then I forgot about the update of the Bayer streaming how-to I promised earlier. In the future, feel free to ping me!

I've just updated the How to enable raw streaming on Logitech webcams article. The change actually explains your question.

As you correctly noticed the deprecated UVC_GUID_LOGITECH_XU1 extension unit is missing from newer cameras. But the UVC_GUID_LOGITECH_VIDEO extension unit provides the exact same controls (though they have different IDs). There is an updated patch available as part of the how-to and with its help you'll be able to switch your QuickCam Pro 9000 to Bayer mode.

Let me know if you have any additional questions.

I know that I am using an old camera, but in case someone knows the answer ... Does the QuickCam Pro 4000 support UVC, and hence raw Bayer?

M/N: V-UJ16
P/N: 861095-0000
OS: Windows XP

I am currently using the camera to capture still images (1 Mpix) and have discovered that the images have some sort of preprocessing done on them that is undesirable for my purpose. I would thus like to explore writing a simple Win32 application that captures raw Bayer mode images. Of course, if the Pro 4000 cannot support raw Bayer then I will go and buy another camera (actually more than one), but I would much rather just stick with what I already have, since the 1 Mpix resolution is sufficient.

By the way, when I originally bought my Pro 4000 cameras I contacted Logitech about software development with that camera and they provided me with an SDK --- actually I think it was just a link to a page on their web site from which I downloaded the SDK.
With that simple SDK I seem to remember just dropping a video preview object onto a Borland C++ Builder form and "Voila!", I had an application that would display video from the camera.
I since have misplaced (or permanently erased) that SDK, but I am wondering whatever happened to that SDK on the Logitech sites. Everyone in the forums keeps saying that Logitech does not provide any SDK's, but I know that was not always the case.
I can only speculate that the current lack of that old SDK is because the method used back then (in that SDK) was not DirectX, and that old method is now not supported. Can anyone confirm what I am saying?

The QuickCam Pro 4000 does not support UVC or the Bayer format.

As far as the SDK is concerned, there indeed used to be an SDK many years ago but it has been discontinued because it does not work using newer cameras and DirectShow. We are thinking about reviving it but no decision has been made at this point.

For reference, the old SDK is still available from Logitech.

Thanks.

Thank you for the quick replies.

I also just found a more comprehensive list of cameras that indicates UVC compliance or not.

http://logitech-en-amr.custhelp.com/cgi-...faqid=5336

Drat. I guess I will have to spend some more money.

Also, thanks for the information on the SDK. I will be going the DirectShow route instead, but I appreciate knowing that I haven't lost my mind.
