can I install it on debian etch?
and I think that I'll have to get out the older gspcav1 20071224 ...
and can I found it?

May you try it? If the image is not good, could you take

Hi,

I've downloaded and compiled the V2 0.0.23 gspca driver. I'm using the
Vimicro 0x307b camera

I only get a black image with gqcam while camorama freezes.

Dmesg output:

Now I've compiled and loaded jpegdec module and gqcam prints no output.
Instead, the program shows a white rectangle as the webcam image and states
"Speed - Calculating" even when launched with -m 1 option (max 1 frame per
second).

In one occasion, spcaview has shown the usual black rectangle but with a
green horizontal bar on top, of about 5% of the output. I don't know if I've
done something different to get it, but I've been unable to get it again.
Cool :)

Normal error: luvcview works only with v4l2 drivers.

You may try. If the compilation is correct, the driver should work.

>vraiment "codeur" ou programmmmeur....

This program is also a v4l2 client, so it does not work with
gspca v1. To compile, just do:
	cc grab.c -o grab
Then, when the camera is plugged-in, do:
	./grab
and send me the file toto.jpg.

BTW, the frames output by zc3xx are not correct. It should be fixed
in the new version 0.0.24.

Bonne fin de journée.

Re bonjour,
Accessoirement,
  peut-etre quand utilisant le patch que tu as ici:
http://moinejf.free.fr/
je pourrais faire fonctionner cette cam,
mais comment utiliser ce patch?

There was a bug in the previous version: the frames lack a JPEG header.
It is fixed in the new version 0.0.24.

I have no 307b camera, but you may send me information for I make
it work. First, try the last version with the small program I sent
this morning (grab.c). The file it creates (toto.jpg) should be
displayed by any graphical program (evince, dillo, firefox...).
If the picture is correct, the driver should work with any client
understanding JPEG frames such as luvcview, and it should work
too with the help of 'jpegdec' for v4l1 clients as Skype or vlc.
If the picture is not clear, send me the file for I have a look.

The other possibility is that you cannot get a picture (grab stays
hung). In this case, activate the debug trace by:
	echo 0x3f > /sys/module/gspca_main/parameters/debug
Then, plug the camera, do the grab and send me the kernel trace.

Regards.

   impossible de faire modprobe gspca

gspca V2 n'a pas le même nom de module il faut charger gspca_main et ensuite le module dédié a ta camera gspca_zc3xx, 
s'ils ne sont pas chargé mais as tu fait :  depmod -a après voir copier les .ko dans /lib/modules/.... car les modules 
doit être autochargés lorsque la camera est branchée.

gspca V2 hasn't the same module name, you have to load gspca_main and next the dedicated module for your webcam if it's 
doesn't. but do you run depmod -a after copying .ko in /lib/modules/... cause the module may be autoloaded while the 
webcam is plugged.


Jean-François: I quickly test 0.0.24, at work CS110 on USB2 give an image in camorama and luvcview output is green with 
artifacts.  No luck with 0ac8:305b zc3xx (but it neither works with gspcav1). I'll give longer test at home.

Ok, ... j'ai fait ce qui est ecrit dans le readme, a savoir:

make -f Makefile.standalone

mais comment puis-je savoir le reste?
il n'y a pas d'autre details sur l'installation,
donc, je copie "a la main" tous les  .ko dans /lib/modules/quoi...?

..et le depmod -a : non vu que je n'ai pas fait ce qui precede

debian:/home/jmarc# modprobe gspca_main
FATAL: Module gspca_main not found.

debian:/home/jmarc# modprobe gspca_zc3xx
FATAL: Module gspca_zc3xx not found.

desole je ne suis pas tres bien habitue a installer des drivers...

I did like it's in "readme"

make -f Makefile.standalone

But how can I have knowedge about the others things?
there is nothing about installing, only the
"make -f Makefile.standalone",
so do I cp files.ko by hand, and where exactly?
...and the depmod -a no because  I did'nt do the others...

debian:/home/jmarc# modprobe gspca_main
FATAL: Module gspca_main not found.

debian:/home/jmarc# modprobe gspca_zc3xx
FATAL: Module gspca_zc3xx not found.

sorry, I'm not fine in drivers installing...

merci,
Jmarc

Bon, je n'avais pas vu le message de jean-françois:

jean-françois a dit:

Il faut faire soit:

  alors que le 2) n'est à faire
qu'au changement de version du driver (ou de kernel).

ouf

Quand c'est fait, tu enfiches la webcam, et si tu n'as toujours pas
de /dev/video0, tu m'envoies le résultat de:

	dmesg | tail -30

donc  vu que je n'ai pas de/dev/video0,
voici le: dmesg | tail -30

pas de soucis, ce n'est normal on a pas la science infuse... faut bien apprendre surtout en informatique, tout les jours il y a de nouvelles choses..
Bref  make -f Makefile.standalone ne fait que compiler le driver, pour la version 2 de gspca il est composé en un module principal et de module
spécifique à chaque type de webcam (fonction du bridge).
Une fois que tu as exécuté make -f Makefile.standalone dans le répertoire des .o et des .ok en plus, le système ne sait en aucune maniéré qu'ils sont
là. Leur place doit être dans /lib/modules/X.Y.Z/sousrep , où X.Y.Z est la version du kernel pour lequel de driver a été compiler dans le cas présent
tu n'as pas le choix, c'est la version courant (uname -a pour avoir la version).
Tu peux créer un sous-répertoire pour y déposer les drivers: mkdir /lib/modules/X.Y.Z/kernel/drivers/usb/media/  (pour respecter l'arborescence qui
classifie les drivers j'ai choisi kernel/drivers/usb/media/ mais cela peut être gspca ou autre).
Et ensuite faire un cp *.ko /lib/modules/X.Y.Z/kernel/drivers/usb/media/.
Enfin il faut faire un depmod -ae qui va regarder les fichiers .ko dans l'arborescence /lib/modules/X.Y.Z pour exporter les "services" (support de tel
matériel ou  support de tel protocole ...) qu'ils proposent et résoudre les dépendances qu'ils peuvent y avoir entre-eux.

donc pour faire simple
make -f Makefile.standalone
(mkdir /lib/modules/X.Y.Z/kernel/drivers/usb/media/ )
rm /lib/modules/X.Y.Z/kernel/drivers/usb/media/gspca*.ko
cp *.ko /lib/modules/X.Y.Z/kernel/drivers/usb/media/
depmod -ae

reste plus qu'a brancher la webcam :)

pour les nouvelles version ne pas oublier comme je le fais parfois :/ de décharger les modules avec

rmmod gspca_zc3xxx
rmmod gspca_main

puis pour les recharger avec modprobe gspca_zc3xxx

Aussi avec lsmod  tu peux voir la liste des modules qui sont chargés, la commande dmesg te donnera les dernières informations/évenement (log) du kernel.


Aurélien

ps: Jean-François qui visiblement a été plus rapide .... je poste quand même cela complètera
ps2: je vais faire une version modifier du Makefile pour qu'il fasse tout cela

C'est bizarre,

il y a 5 mn je n'avais pas de /dev/video0..
je pars me faire un cafe....je reviens, je lance luvcview, il s'ouvre 
(super) mais...
avec l'ecran noir... c'est un bon debut? hein...
et
debian:/home/jmarc# luvcview
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
donc le /dev/video est bien la...mais pour combien de temps? docteur...

et voici pour le dessert:
le grab aux pinces d'or

debian:/home/jmarc# ./grab
width: 640 bytesperline:640 height:480 sizeimage:92160
--> sizeimage: 614400
select timeout


c'est court...mais c'est deja le bon chemin....

merci,

Ach,

please don't top post.

Hello Thiago, Roger and Jmarc,

It seems you have the same camera. As you know, it may have 2 sensors.
The sensor in gspca v1 and v2 (OV7620) is not the right one. So, in
the last gpscav2 release (0.0.26), I set the exchanges for the
sensor PO2030. May you try it?

Thank you.

Ah, oui on dirait que la nouvelle version est prometeuse...
donc avec luvcview 

#luvcview 
ou
#luvcview -d /dev/video0

j'ai une reele image mais rayee de noir, et dans le tableau de bord son icone
clignote...

ca avance, ca avance,

camorama: image rayee 3 types de rayures: couleurs freezes, noir, gris

camstream : non

spcaview: non ne s'ouvre pas

super, 
Jmarc

Bonjour,

1) Voici l'image obtenue avec luvcview pour la 0ac8:307b en piece jointe

lesautres applications ne repondent pas ou ne se connectent pas ou 
refusent d'ouvrir une des deux cameras.

2) Voila qqchose de curieux:

# lsmod

gspca_zc3xx            83296  0
gspca_main             18880  1 gspca_zc3xx
zc0301                 44708  0
videodev               21120  2 gspca_main,zc0301
v4l1_compat            12036  1 videodev
v4l2_common            20448  2 zc0301,videodev
usbcore               112644  8 
gspca_zc3xx,gspca_main,zc0301,wacom,usbhid,ehci_hcd,uhci_hcd

je me demand ce que fait ce zc0301 ici ?
ais-je fait une erreur, a l'installation?

3) Pour ce qui est de la 0ac8:301b elle ne fonctionne qu'avec luvcview

Bon Dimanche,
amicalement,

Jmarc Dufour

Hello all.

I'm trying to set up web camera work 0ac8:307b. Build latest version of

You should use a video viewer (mplayer, cheese, vlc, xawtv...).

Thanks for your reply.
The problem is that I have to this host only remote access via ssh and can  
not use graphic tools. When I try to write data from the device is also an  
error.

I need to just get jpeg images from the camera.
On the other host, where the camera 0ac8:305b everything works well. As  
with version gspcav1 and with gspca v2. When I access the device  
/dev/video using dd I get the data.

Try with v4l2 apps, since v4l1 wont work without libv4l conversion.
As a matter of test, dowload:
    http://moinejf.free.fr/svv.c
and
    svv -g   should dump a image.dat.

if you have any doubt, visit my blog for more information:

After that created the file image.dat, 921600 byte size and filled with  
the values of "0x12"

Once launched, with key "-g -r" get image.dat size 6594 byte and is black  
image.
Does it matter version libv4l?

As you can see, your webcam has an unknown sensor. To make it work, I
need a USB trace done under m$-windows. This one may be done by
sniff-bin 1.8 or usbsnoop-2

Good day.
I did, log file in attachment.

Hello,

I got the file, thank you.

I found a problem on the sensor detection, but as your trace
contains only the plugging of the webcam, I am not sure it works.

So, if it does not work, you may:
- either check by yourself the sensor type,
- or send me a usbsnoop with 1 second of video streaming.

To check the sensor, you may force its type in the zc3xx parameters.
As root, do
	echo n > /sys/modules/gspca_zc3xx/parameters/force_sensor
with n = 0..16. Don't forget to unplug / replug the webcam after
changing the value.

Best regards.

Hello.
When I do usbsnoop with a 1 seconds of video stream, the log file is 40  
megabytes.
May be I can cut any part of it?

Hello,

I attached a usbsnoop parsing tool. It extracts and formats all the
important information.

Regards.
