According to the USB specs, you can go 5 hubs deep. There is a maximum distance of 30 meters I believe. This would give with 6 5meter cables. > 2. Can one capture sound with this camera.

I tried this too and had the same problems. But fortunally everything works fine, if my app captures from both cameras (that's what I want).

Or can anyone give me some hints ? AFAIK, the terratec-cam should work fine. All cameras supported by our driver have the same chip inside. So from the electronic specifications (resolution, compression, ...) there is no difference between the cameras. There might be differences with respect to lens quality, design, etc. but I have no idea which one is better with respect of those criteria. Anyone on the list has cameras from different vendors? In what do they differ? Anyway, all cameras known to work with our driver are listed at webcam.sourceforge.net. If you know of any additional model let us know.

Because cpia needs videodev, modprobe will automatically load videodev first. Because cpia_pp needs parport, modprobe will automatically load parport. If you set an alias for parport_lowlevel to parport_pc, parport will automatically load parport_pc. I haven't tried it, but if your camera is you only v4l device, you can probably alias char-major-81 to cpia and have everything happen automatically. To summarize: alias parport_lowlevel parport_pc alias char-major-81 cpia post-install cpia_pp echo "compression_mode:none" >> /proc/cpia/video0 and everything should work like magic. Scott J.

Hi! I hope somebody knows what is happening ;). Well, I have a Zoom Cam USB and I'm using it with the 2.2.14 kernel, the USB backport (from 2.3.50 kernel) and the 1.0 CPia driver for linux. Well I'm developing a real time video processing application with it, using v4l and gtk+. The problem is that sometimes the biprocessor box I'm ussing is completly locked when I'm running mi app with KDE (is this important?) and the only thing I can do is restart the computer (neither pings nor change to a text console works).Of course, my program maybe is completly wrong but I think maybe there is a problem with the USB stack or the CPIA driver.

AEC/ACB are now more effective for single frame grabs. In some cases though, AEC may switch back & forth between 2 exposure setings.

The error above is -84 which is EILSEQ on i386. I forget what that code means off the top of my head, but I think it's a bitstuffing error.

Thank you for suggestions. I tried several things and here are my observations: 1. With driver 1.0: The Gqcam was working stable when I set "Contrast" to a small value like 0-10. When I increased this number I got I/O errors pretty soon. One thing I noticed is that frame rate with still image (that is when I am not moving in the camera) was getting from 7-8 fps to 10-11 even 15. The errors are the same as in previous letter. When contrast is set to 0, gqcam works just fine, though I was able to provoke I/O errors by quick change of lighting (or maybe it was a coincidence) 2. With driver 1.1 Overall it works better.

Hello! I've got a 3Com Homeconnect USB webcam. I tried building kernel 2.3.99pre9 and to patch it with CPiA 1.1. There was a lot of things during the kernel installation I had to do manually (and I don't even think that it's all 100% correct yet). But is the 3Com Homeconnect USB webcam supported in the first place? I have just mailed 3Com asking for hardware specs and/or Linux drivers. And I'm actually considering to develop this driver if it can be done within a few hours :) But is anybody else working on this? Just for the record, here is what I did for installing the kernel and all: Configure kernel 2.3.99pre9 Enable: USB USB audio Video For Linux CPiA driver CPiA lowlevel USB And I patched with the CPiA 1.1 source. I think it was: make unkernel-2.3 make kernel-2.3 Making the kernel: make dep make bzImage (and make bzdisk, since I boot from floppy) make modules make modules_install Make the /dev/video0 and /dev/video devices: mknod /dev/video0 c 81 0 ln -s /dev/video0 /dev/video Add the following to /etc/conf.modules: path[usb]=/lib/modules/`uname -r` path[usb]=/lib/modules/`kernelversion` path[usb]=/lib/modules Now I manually have to execute: insmod videodev (insmod usbcore complains: no module by that name found even though it's there) insmod cpia (insmod cpia_usb says: a module named cpia_usb already exists) After running insmod cpia I see /proc/cpia, but no /proc/cpia/video0 cpia-control won't run because of this. dmesg says: V4L-Driver for Vision CPiA based cameras v1.1.0 usb.c: registered new driver hub usb.c: registered new driver cpia Cheers -- http://www.HardcoreProcessing.com From tgogolin@web.de Sun, 16 Jul 2000 22:04:40 -0700 Date: Sun, 16 Jul 2000 22:04:40 -0700 From: Tobias Gogolin tgogolin@web.de Subject: [cpia] The Sensor defined Resolution Mode Hi All I am new to the List My Name is Tobias (As you can probably see in the from address) And my main reason for subscribing to this list is the 640 x 480 Resolution Mode The informed may know it is the real mode the highest supported by hardware ... is there allready an Implementation out there for this mode from a CPIA Source or is someone working on it ?

I am informed and I can tell you that the CPiA hardware we have written the drivers for cannot go 640x480. You are talking about a different chip. The detection is easy: /* Is it a CPiA? */ if (!((udev->descriptor.idVendor == 0x0553 && udev->descriptor.idProduct == 0x0002) || (udev->descriptor.idVendor == 0x0813 && udev->descriptor.idProduct == 0x0001))) /* GA 04/14/00 */ return NULL; The first one is a normal CPiA such as the Creative Webcam II, the second one is the Barbycam. In any case the highest resolution the chip can do is CIF.

But is the 3Com Homeconnect USB > webcam supported in the first place? This seems to be a FAQ. If I understand the USB-stuff all one has to do is connect the camera to the USB-bus, boot linux with the core USB- support and check the Vendor/Product-Id in /proc. After that a short browsing of www.linux-usb-org should list you the necessary driver. As for this list which is about CPiA based cameras the correct IDs are: VendorId: 0553 ProductId: 0002 Also the Intel Play QX3 Microscope is supported: VendorId: 0813 ProductId: 0001 -Peter -- I will not waste chalk. --Bart Simpson at the blackboard -------------------------------------------------------- Email: Peter_Pregler@email.com WWW: http://www.risc.uni-linz.ac.at/people/ppregler ICQ: 61011460 From Peter_Pregler@email.com Mon, 17 Jul 2000 10:45:29 +0200 Date: Mon, 17 Jul 2000 10:45:29 +0200 From: Peter Pregler Peter_Pregler@email.com Subject: [cpia] The Sensor defined Resolution Mode On Mon, Jul 17, 2000 at 10:35:01AM +0200, Peter Pregler wrote: > > /* Is it a CPiA? */ > if (!((udev->descriptor.idVendor == 0x0553 && > udev->descriptor.idProduct == 0x0002) || > (udev->descriptor.idVendor == 0x0813 && > udev->descriptor.idProduct == 0x0001))) /* GA 04/14/00 */ > return NULL; > > The first one is a normal CPiA such as the Creative Webcam II, the > second one is the Barbycam.

Yes sure and that is why Logitech doesnt want to give out the specs of theyr new Interface Mode Point is Is the sensor used to its fullest potential ? If it is a 300 k pixel sensor its not But every image ever captured with a cpia camera still contains the higher resolution data : Let me Quote some of the comunication I previously led with Jan :============================================================ Looking about what cameras are available out there I think I got a usefull step in understanding more about how these cameras really work ... One Manufacturer (Ezcam USB webcam ) http://www.ezonics.com/dual.html was advertizing 320 000 pixels cmos sensor and resolutions of 640 x 480 = 307200 That mapes pixel to pixel However color is needed 353 x 288 = 101376 I asume there is a filter mask either RGB or CMY So in this mode 3 proximate sensors with individual colors are combined to give one real color aproximation of the light that hits the 3 sensors required --------------------------- I believe the actual sensor is pretty much identical with the Logitech! Logitech is not relaesing its specs because they are more or less the same as others However they figured out - what I am trying to share with you now: > >640 x 480 = 307200 That mapes pixel to pixel ... > >In the highest resolution mode the filter is still in place ... > >Therefore in this mode the camera must try to extract the luminance from > >each pixel Lets Asume Pr = red filtered pixel Pg = green Pb = blue Pr(Pg, Pb) is really also going active with white and grays to black therefore each pixel contains luminance information as well after the capture data is available in a raster with 352 x 288 x 3 x 8 Bit color values We will need some insight of the allignment of the filter masks (you may want to put one under the Microscope :) If you take a lens and look at a delta screen mask of a color Tv every Red is surounded with 3 Pairs of GB same for Green and Blue Because I am concerned sensor makers may have found limitations in chiplayout to rectangular patterns its probably more likely chances are the filter is simply aligned RGBRGBRGBRGRB RGBRGBRGBRGRB RGBRGBRGBRGRB But that would be pretty ineficient especially for what I am saying could be done (or is done by logitech Maybe RGBRGBRGBRGRB BRGBRGBRGBRGRB GBRGBRGBRGRB RG B GB R BR G every block of 3 pixels is complete in itself if we could find out about the physical layout in rows and columns of the sensor or maybe there is even a spec about the filtered sensor ------------------------- Per software it is possible (the logitech implementation proves (not without little failures)) to remap the aquired 352 x 288 data onto a 640 x 480 map Its serious math to do it well : one would best distribute the color info on an area around the location of each filterd sensor (in the expanded file) - then one would go and see how much deviation from the low pass color area one has in an individual sensor cell and create a luminace vector out of the local deviation (cosidering filter color and low pass area color)(and initialy put that in a seperate map) when done combine the maps and have a full color 640 x 480 output ? Some examples: http://ultra.ens.uabc.mx/lvp/visdat/ciaA0473.jpg see the / slanted line on the left where high definition light and color changes get misrepresented into colorful ladders - clear evidence that they are using the technology I am describing http://ultra.ens.uabc.mx/lvp/visdat/d109102851430.jpg see how great it works to get the real detail out of low colorchange images look at the masoned stonewall lines. Again a high contrast /(slant) causes the seperationfaults http://vidar.ens.uabc.mx/lvp/visdat/d001902721500.jpg in comparison the low format analizis causes grainy and unaliased looking effects sometimes ladders apear not to have the color seperation fault However take the time and load the image with a zoomtool and look at the balcony and the luminance jagies those actually contain data that when properly layed out becomes valuable detail ========================================================== Anyhow I am glad to hear that I am talking to the developers themselve :) > I am informed and I can tell you that the CPiA hardware we have > written the drivers for I am looking forward to work with you on implementing the higher Resolution Mode !

Now I have purchase a Zoom Cam parallel port version. I want to use it in a P133 with kernel 2.2.14 & CPia driver version 1.1. My parallel port is ECP/EPP. And I have some problems/questions: - How can I active the DMA with the CPia driver ? + I load parport_pc with parameters: io=0x378 dma=3 irq=7 and I'm pretty sure all are free (looking in /proc/dma and /proc/irq). + Cpia driver is compiled with support DMA options but when I run gqcam the window is white only two!!! parport interrupts are processed and there is one kernel message: "Clearing stall" that cames from the driver function clear_stall. - If I load the parport_pc module without parameters the CPIA driver use PIO mode, so I only can get 2 frames per second :-(. And only at a resolution of 352x288 with is to large. If I try with QCIF I get a read error and the program aborts. But the interesting thing here is that the Windows Cpia driver is working with QCIF size at an acceptable frame rate (I think not in DMA mode). Can you help me to get an aceptable frame rate or a QCIF resollution. I can not figure out what to do.

I've got the same error and it didn't work. I think the "unable to get tuner..." message says it all. When I pointed CVD to my TV tuner card, it displayed a blue image.

The daemon should never try to get tuner-info from the camera. It should query the driver for the capabilities. The driver will report VID_TYPE_CAPTURE, i.e. it has no tuner only capture capability. So the daemon must not try to get further tuner information. -Peter -- Even the thought that a ship was waiting to take him back to Earth did not wipe out the sense of loss he felt at that moment. ------------------------------- Email: Peter_Pregler@email.com From gstalusan@uwaterloo.ca Sat, 29 Jul 2000 13:16:55 EDT Date: Sat, 29 Jul 2000 13:16:55 EDT From: George Talusan gstalusan@uwaterloo.ca Subject: [cpia] USB/SMP lockups I've been getting major lockups (sysrq doesn't work) when using my EZonics EZcam with an SMP-enabled kernel.

Also, I've been looking at cpia.c and in cpia_register_camera there is a comment nothing that the big kernel lock is acquired. But lock_kernel() appears nowhere, yet unlock_kernel() appears in the error paths (but not success!). Adding in or removing the appropriate lock/unlock pairs didn't seem to help any. -- - gst George Talusan, gstalusan@uwaterloo.ca From arjan@fenrus.demon.nl Sat, 29 Jul 2000 19:47:52 +0200 (CEST) Date: Sat, 29 Jul 2000 19:47:52 +0200 (CEST) From: Arjan van de Ven arjan@fenrus.demon.nl Subject: [cpia] USB/SMP lockups In article <200007291714.NAA02722@blanch.math.uwaterloo.ca> you wrote: > I've been getting major lockups (sysrq doesn't work) when > using my EZonics EZcam with an SMP-enabled kernel.

There are 2 things that cause a crash for you: 1) The cpia driver in 2.4.0-test5 does corrupt memory (fixed in the sourceforge version) 2) The USB stack in 2.4.0-testX has a very ugly race that is _very_ repeatable.

They will not be allocated (an therefore reported as free) as long as the camera device is not open.

Can you compile the driver with debugging on and send us the complete syslog output (all from the beginning of inserting the parport driver to the crash of your application). Also the respective proc files (interrupt, dma, video/cpia, parport/...) would be nice. I just tried 1.1 and it stills works fine for me with 2.2.16 and DMA on. I get a thruput of about 400kB/sec with about 30% load on a PIII 350 CPU. -Peter -- Even the thought that a ship was waiting to take him back to Earth did not wipe out the sense of loss he felt at that moment. ------------------------------- Email: Peter_Pregler@email.com From jmbuena@isys.dia.fi.upm.es Mon, 31 Jul 2000 12:55:56 +0200 Date: Mon, 31 Jul 2000 12:55:56 +0200 From: Jose Miguel Buenaposada jmbuena@isys.dia.fi.upm.es Subject: [cpia] DMA & CPia Parallel port Hi again !! Peter, I send version some more information abaut my problems with the CPIA Zoom cam parport version.

Only the PIO mode works and only with CIF size, with QCIF size I get a "read(...)" error and in /var/log/messages: cpia.c: parse_picture(2156): header not found And I can not read images anymore. At least with the 1.1 version of the driver I can read images with compression_mode:quality (with the 1.0 version I only can read images with compression_mode:none) up to 2 fps with CIF size.

I will be happy only getting images in QCIF size, althougt I can not use DMA, but if I can work with DMA mode I'll be very, very happy. If you need some more information don't hesiate to contact me. Anyway thanks a lot for your time and your great work with the driver. Regards.
