Hi Allwyn,

The gspca driver / framework is now in the kernel and discussion about
it shall occur in the LinuxTv mailing list (see http://linuxtv.org and
http://vger.kernel.org/vger-lists.html#linux-media).

So, I think that this list may be closed.

Thank you.

Hi Allwyn,

I agree with you that the list should be closed and the project be declared 
unmainstained. The spca50x projecthas had a relatively long and succesfull life, 
but all good things come to an end. Or in this case, the code lives on 
elsewhere, in the spirit of open source :-)

Cheers,
Tomas

[Spca50x-devs] Is anyone still using this list?

[Mr A. F. <web...@st...>]

As this list has not seen any traffic in over 6 months, and all development is 
now being done on the v4l lists, I think my objections to shutting this list 
down back in 2007 are now irrelevant. 

Is there anyone who thinks this list (and/or this sourceforge project in 
general) should remain open? Specifically, Michel and Jef, are you still 
interested in having this mailing list around?

If no-one has any objections, I will close this list on 31 March 2011, and put 
the project into unmaintained state.

Thoughts?

Cheers,

Allwyn.

[Spca50x-devs] Problem with zs211

[delafond g. <ge...@de...>]

Hi !

I am trying to install a little no-name webcam.

Plugin it in the USB port shows :

Jun 16 16:04:14 localhost klogd: usb 3-3: new full speed USB device using 
ohci_hcd and address 7
Jun 16 16:04:14 localhost klogd: usb 3-3: device descriptor read/64, error -62

error -62
Jun 16 16:04:16 localhost klogd: hub 3-0:1.0: unable to enumerate USB device 
on port 3

Once only, I got a good message, inserting gspca zc3xx, showing device 
0ac8:307b
and creating a /dev/video0.

Even in this case, I could not open it with a webam program like cheese 
(/dev/video0 was grey).

I tired it on Mandriva 2010 and Ubuntu 10.04

the windows driver is named zs211.

Is there a way to get it working ?

Many thanks

Gerard

Hello Shahar,

A driver for this webcam is available (you may find it in the last
gspca version that I have just uploaded - 2.9.6 - the subdriver is
'gspca_tasc.ko').

The only problem is that nobody could yet decode the images! (Jens,
Jean-Yves, any news?)

About the list, all the linux video stuff is hosted at LinuxTv.org and
the linux-media mailing-list at vger.kernel.org (see Cc:).

Best regards.

Hello Alexandru,

I am not sure to be able to use logs from USBlyzer.

Well, as the gspca / vc032x evolved since last year, may you give me the
last lines of 'dmesg' after plugging in the webcam? (also, tell me which
is the gspca version)

Then, which application(s) do you use to view the webcam images? Do you
preload the v4l library?

Best regards.

[Alexandru B. <abo...@gm...>]

hi Jean-Francois,

I finally got to my sister's computer. Installed ubuntu 9.10 yesterday to
see the webcam displaying random patterns unrelated to an image (looks like
memory garbage).


I then booted into windows and tried using sniff-bin and snoopy and all but
none of them would create a long file. I am at a loss why.

I did a sniff with USBlyzer; if you want, I can send you the ulz file you
can open with USBlizer under windows (they have a free 30 day download with
no restrictions).

Please let me know if this will be enough, or should I coax my sis into
purchasing a supported webcam : )

Thanks a bunch.
Alex.

[Spca50x-devs] gspca_vc032x: Sensor MI1320 in Samsung Q1 Ultra not working

[Florian E. <fl...@bu...>]

Hello everyone,

I've installed the latest & greatest v4l drivers from
http://linuxtv.org/hg/~jfrancois/gspca/ and tried to use the camera on a
Samsung Q1 Ultra with them. The camera reports as 

Bus 001 Device 005: ID 0ac8:c301 Z-Star Microelectronics Corp.

and the gspca_vc032x driver recognizes it - dmesg shows:

[  703.298585] Linux video capture interface: v2.00
[  703.313857] gspca: main v2.7.0 registered
[  703.321625] gspca: probing 0ac8:c301
[  703.322554] vc032x: check sensor header 20

[  703.511764] usbcore: registered new interface driver vc032x
[  703.511775] vc032x: registered

However, no video tool works. cheese always reports "libv4l2: error
dequeuing buf: Input/output error" and the svv tool from the linuxtv
website just shows a green screen, nothing else. At one point, I've also
seen an error message in the log along the lines of "frame overflow
616416 > 614400".

Does anybody have a hint for me how to fix this?

Thanks, Yours, Florian

Hi David,

The webcam 0c45:613e has a sn9c120 bridge with a sensor ov7630 (not
7648). In the newest kernels, it is handled by 2 drivers: sn9c102 and
gspca/sonixj. It seems that the sn9c102 does not recognize the sensor
(your trace). gspca/sonixj should do it. May you remove the sn9c102
module from the kernel library and check if the gspca/sonixj works?

Best regards.

Hello Sudipto,

Did you try the last gspca v2 from my test repository? As there is a
probe sequence in the vc032x subdriver, the kernel log should contain
the sensor name. What is it? If you cannot get images, may you tell me
what is wrong? (does 'svv' display some image? does 'svv -rg' create a
raw image? what are the last kernel messages? ...)

Best regards.

[Spca50x-devs] HP VGA cam.

[Sudipto S. <xtr...@gm...>]

I'm trying to write a driver for the HP VGA camera. USB ID: 15b8:6002. 
The sensor is 7131r, and the bridge is probably vc0323 (although the inf 
says it's vc0326). It's inf is the same inf which includes the po1200 
sensor, which was added in December last year (The HP 2.0 Megapixel 
camera). I am trying to use usbsnoop in a windows installation, but the 
log size just does not cease to come to a halt (as is specified in the 
microdia site), thereby leaving me unable to snoop the init sequence. 
What might be wrong?

Also, is this the same sensor as hv7131r, as in vc032x.c?

Hi Asif,

I am very busy, but I can have a look on your traces.

As a first step, I would know a bit about the USB exchanges. I'm joining
a usbsnoop parser. May you use it with your trace and send me the
resulting output?

Cheers.

[Spca50x-devs] ip293x for linux

[Asif I. <va...@gm...>]

I have a ipassion webcam (below) that I need help with building a
driver for linux. I am using ubuntu 9.04

   Bus 003 Device 002: ID 1b3b:2936 iPassion Technology Inc. PC
Camera/WebCam controller

I have collected about 750mb of usbsnoop data from windows.

Is there a public place where I can dump a little bit of that data and
get some help to make a linux driver?


Thanks

Hi Aveek,

Which driver are you using? (FYI, gspca v2.7.0 is included in the kernel
2.6.31-rc5, but gspca v2.5.0 in kernel 2.6.30 may work better)

Also, the pixel format conversions are now done by the v4l2 library. It
is better to use standard viewers as vlc (1.0.x) or mplayer instead of
specific ones as luvcview.

Best regards.

I got it working. Now the image is displayed in its original size. 
But I dont see proper color, its a kind of black/white picture I am getting using my modified luvc application.  My camera gives bayer and JPEG pixel format. I have applied the patch provided in the link below and modified it to get full scale picture. But I dont get proper color. Is it a driver issue? My camera is "0c45:613c" (SN9C120).

I don't know if this was ever merged, but the instructions and patch are using 
gspca V1, and development has long ago moved over to gspca V2... As far as I 
konw, there's basically no-one working on gspca v1 any more...

Cheers,

Allwyn.

There was this posting in skype forums: (a patch was included)
http://forum.skype.com/index.php?showtopic=127561&view=findpost&p=574031
See below for a summary. http://forum.skype.com/index.php?showtopic=127561&view=findpost&p=715021

Can any spca devel confirm if this is upstream (merged) ?

Many thanks,
Karthik
