 |
|
It appears only in a color (green-like in spcaview or aMSN, and blue in gqcam).
Its a Genius Webcam that uses the gspcav1 drivers.
Here is the Kernel .config in Multimedia section:
| Code: | #
# Multimedia devices
#
CONFIG_VIDEO_DEV=y
# CONFIG_VIDEO_V4L1 is not set
CONFIG_VIDEO_V4L1_COMPAT=y
CONFIG_VIDEO_V4L2=y
CONFIG_VIDEO_CAPTURE_DRIVERS=y
# CONFIG_VIDEO_ADV_DEBUG is not set
CONFIG_VIDEO_HELPER_CHIPS_AUTO=y
CONFIG_VIDEO_VIVI=m
# CONFIG_V4L_USB_DRIVERS is not set
# CONFIG_RADIO_ADAPTERS is not set
# CONFIG_DVB_CORE is not set
CONFIG_VIDEO_BUF=m
# CONFIG_DAB is not set |
Any help would be thankful  |

Did you try with only v4l1?
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L1=y
CONFIG_VIDEO_V4L1_COMPAT=y
# CONFIG_VIDEO_V4L2 is not set
CONFIG_VIDEO_CAPTURE_DRIVERS=y

Sure, i have it already.
If not, gspcav1 will not compile  |

Sorry for reviving this post.
But i cant set CONFIG_VIDEO_V4L1=y together with CONFIG_VIDEO_V4L1_COMPAT=y
In the kernel configuration GUI, each option disables another. |

Hi,
I have the same issue with a Quickcam pro 4000, I tried both pwc from the kernel and from external module but it didn't help.
Any idea appriciated.

Frostwarrior,
| Code: | │ │ [*] Enable Video For Linux API 1 (DEPRECATED)
│ │ --- Enable Video For Linux API 1 compatible Layer |
This means that Enable Video For Linux API 1 (DEPRECATED) being selected forces Enable Video For Linux API 1 compatible Layer to be set on, which is what you want.

mamac,
The pwc module works for me. From my /proc/bus/usb/devices, my webcam identifies as | Code: | P: Vendor=046d ProdID=08b2 Rev= 0.00
C:* #Ifs= 3 Cfg#= 1 Atr=a0 MxPwr=500mA |
Hmm, it says it wants 500mA. Thats all the power a root hub can provide for all connected devices. In other words, it can't share a root hub with anything.
My cam is connected to a powered USB hub. You also need the v4l1 settings in my previous post.

How do you achieve this configuration?
Here they say we don't have all features for the webcam because of a lack of information from the vendor. Could this issue also affect color management?
Thank you

Sorry, there was a mistake in the listing of my configuration.
This is the correct one:
| Code: |
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L1=y
CONFIG_VIDEO_V4L1_COMPAT=y
CONFIG_VIDEO_V4L2=y |
I wondered if switching the CONFIG_VIDEO_V4L1 (second row) to yes would solve the problem.

No, it won't...I'll try to install the webcam on another gentoo box and see what happens.

mamac,
Post your /proc/bus/usb/devices file, when the webcam is connected, so we can see what you really have.
The numbers will tell whats inside the cam, which is what counts, not what the packaging says.

Sorry but that doesn't ring any bell to me...
Here if you want to see the result.

mamac,
Thats the same cam as I have, and itworksforme. From the top, your kernel needs:-
| Code: | │ │ --- USB support
│ │ <M> Support for Host-side USB
│ │ [*] USB device filesystem
│ │ <M> OHCI HCD support
│ │ --- USB Imaging devices |
--- means forced by some other setting. If you can choose these settings, put them on. You may use either <M> or <*>, since it works with modules or built in.
Under Multimedia Devices, you need | Code: | │ │ <M> Video For Linux
│ │ [*] Enable Video For Linux API 1 (DEPRECATED)
│ │ --- Enable Video For Linux API 1 compatible Layer
│ │ [*] Video capture adapters ---> |
Under Video capture adapters, choose [*] V4L USB devices --->
| Code: | │ │ <M> USB Philips Cameras
│ │ [ ] USB Philips Cameras verbose debug |
Its important the debug is off. Make the USB Philips Cameras support a module, since that makes it easy to pass parameters to.
When you load the module, you can pass it the following parameters | Code: | parm: size:Initial image size. One of sqcif, qsif, qcif, sif, cif, vga (charp)
parm: fps:Initial frames per second. Varies with model, useful range 5-30 (int)
parm: fbufs:Number of internal frame buffers to reserve (int)
parm: mbufs:Number of external (mmap()ed) image buffers (int)
parm: trace:For debugging purposes
parm: power_save:Turn power save feature in camera on or off (int)
parm: compression:Preferred compression quality. Range 0 (uncompressed) to 3 (high compression) (int)
parm: leds:LED on,off time in milliseconds (array of int)
parm: dev_hint:Device node hints (array of charp) |
if pwc is already loaded, you must before you can try new params.
Hint: you cannot use vga mode above 15 fps without compression as USB 1.1 does not have the bandwidth.
I used to use vga and 15 fps because thats whats set in in my /etc/modules.d/pwc but its all commented out now.

Now using the pwc kernel module but still no color.
I didn't set any parameter for the module but I don't think that affects the color.
Could it come from the application (w3cam in my case) ? vidcat is also in black & white...

mamac,
I use xawtv and Ekiga (VoIP). So maybe it is your application

No...
I installed the webcam on my laptop and desktop (with Gentoo of course) and vidcat (that comes together with w3cam) gives color images.
So:
- on my Soekris with usb 1.1using w3cam and vidcat -> black & white
- on my laptop and desktop with usb 2 using w3cam and vidcat -> color
Could it be related to usb 1 or 2?

mamac,
Your /proc/bus/usb/devices says
| Code: |
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=046d ProdID=08b2 Rev= 0.00
C:* #Ifs= 3 Cfg#= 1 Atr=a0 MxPwr=500mA |
that your webcam is USB 1.1. Thats the D: Ver= 1.10 part.

Frostwarrior,
Google says you need the spca5xx driver. Note the MxPwr=500mA entry in your cam output.
That means the root hub that your camera is connected to cannot support any other devices that are powered via the USB cable or none of them will work. Its masked in portage | Code: | * media-video/spca5xx [ Masked ]
Latest version available: 20060501-r2
Latest version installed: [ Not Installed ]
Size of files: 188 kB
Homepage: http://mxhaard.free.fr/spca5xx.html
Description: spca5xx driver for webcams.
License: GPL-2 |
Its also very old. You will need a properly installed and configured kernel to build this kernel module against.
The binary kernel provided by copying the kernel from the liveCD will not work.
There is also media-video/gspca which is a development of media-video/spca5xx from the same website. In view of the way the kenrl has changed since the release date of media-video/spca5xx, go to the web site and read. It may not build with recent kernels.

Hi there. Dunno if anyone is watching this thread anymore, but i hope so (Neddy Seagoon, save me)
I just bought a... well.. uhh.. "competition's" webcam (microsoft lifecam vx-3000). already got it running with gspcav1 driver. unfortunately, with the same green gamma image. anyway to solve this?
is there a way to shift the bits it's getting, so to get the whole rgb data? BTW, why green? any particular reason? its the middle byte, so supposedly, it should be either red or blue in case of error, but green???
eitherway, any idea as to how to solve this?
thanks
EDIT: kinda solved. i have the image with a almost normal color. but it shows a lot of areas with some strange blue. the image quality is awful. any ideas?
