 Posted: Sat Apr 24, 2010 2:54 am Post subject: Logitech QuickCam 046d:08da & 046d:0870 [SOLVED] |
 |
|
This is an old camera that i use as security cam and its has been working with thh driver package qc-usb, now removed from portage due to kernel built in driver support.
Hardware info:
| Code: | | Bus 006 Device 003: ID 046d:0870 Logitech, Inc. QuickCam Exp |
Support:
| Code: | | stv06xx 046d:0870 Dexxa WebCam USB |
Reference: http://www.kernel.org/doc/Documentation/video4linux/gspca.txt
Matching driver kernel driver:
gspca_stv06xx
And compiled as module:
| Code: | # lsmod | grep gspca_stv06xx
gspca_stv06xx 19664 0
# lsmod | grep quickcam
quickcam 59936 0
|
Working problems:
-Camorama is only able to get a black video with scratched blinking lines across and reporting 82 fps !!
-amsn gets a black video input and freezes
-skype gets nothing. even the square where the video should be does grey (same colour as skype GUI)
-ekiga crashes
-linphone-3 gets a black screen video
and mplayer ... reports that the driver should be use only with v4l2 and not v4l

Hi,
If you look at the warning when running mplayer:

So to solve this you need to follow the directions in the http://en.gentoo-wiki.com/wiki/Webcam#Libraries .
How to use it is described on the same page.
| Quote: |
You might need to install media-libs/libv4l and run "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so application" in order to make some programs which only work with v4l1 work on v4l2. Remember also to emerge those applications with the v4l v4l2 flag.
|
Homepage for libv4l http://hansdegoede.livejournal.com/3636.html
So emerge libv4l and test. |

Ok so i took a look at this documentation and i already had all of this except media-tv/xawtv.
So lets review:
| Quote: | | If you are using udev there should now be a device file in /dev/v4l/ called video0 (or video1, video2 or video3, for that matter). If the device is not created, check dmesg for errors and useful messages. |
| Code: | # ls /dev/v4l/
by-id by-path
# ls /dev/v4l/by-path/
pci-0000:00:1d.0-video-index0 pci-0000:00:1d.7-usb-0:4:1.0-video-index0
# ls /dev/v4l/by-id/
usb-046d_0990_6CB3DD11-video-index0
# ls /dev/ | grep video
video0
video1
video1394 |
Note: by ID it shows only one video device while by path it shows 2. Why ?
Video0 = 046d:0870 Logitech, Inc. QuickCam Exp
| Code: | # emerge -pv media-tv/xawtv
These are the packages that would be merged, in order:

There are no v4l v4l2 flags for this package. But i do have v4l and vl42 in make.conf
| Code: | $ ls /usr/lib/libv4l/v4l1compat.so
/usr/lib/libv4l/v4l1compat.so |
Best result was with mplayer:
| Code: | | $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so mplayer tv:// -tv driver=v4l:width=352:height=292:device=/dev/video0 -fps 15 |
Which provided a black video output during a very sunny day.
Moving to the second recommended URL.
I didnt understand the information of the one very well but lets see.
| Quote: | | Just replace open("dev/video0", ...) with v4l2_open("dev/video0", ...), ioctl with v4l2_ioctl, etc. libv4l2 will then do conversion of any known (webcam) pixelformats to bgr24 or yuv420. |
Replace it where ?
The only terminal command options i have are:
| Code: | | v4l-conf v4lctl v4l-inf |
But even so i tried. I take it that i skiped something...
| Code: | $ export LD_LIBRARY_PATH=`pwd`/lib
$ export LD_PRELOAD=`pwd`/lib/v4l1compat.so
$ camorama
ERROR: ld.so: object '/home/user/lib/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored. |

OK,
What is the output if you start xawtv in a console inside X.

Ex:
$ xawtv
This is xawtv-3.95, running on Linux/x86_64 (2.6.33-gentoo-r1)

OK.
The driver loads OK. But the stream is not read.
I have looked around and found that when they changed it
to v4l2 and incorporated it into the kernel, they have had
some problems regarding support of all sensors.
And the HDCS-1020 that you have in the cam seems to be one of them.
Changes have been made and the driver is up to 2.8.0 now in the kernel (what I can see).
Maybe a later kernel then 2.6.30.3 would work.
/Regards |

A quick update about this issue that might help other people.
While trying to fix this problem i also got my hands on another system that also had the same problem with another logitech quickcam:
| Code: | | Bus 002 Device 003: ID 046d:08da Logitech, Inc. QuickCam Messanger |
The kernel driver for this cam should be compiled as module and it's name is gspca_zc3xx which requires gspca_main
| Code: | | ZC3XX USB Camera Driver |
This cam was working with mplayer and amsn without any extra parameters (by default) but not with other applications such as skype, linphone-3, camorama.
In other so work with skype the following, needs to be done on the command line:
| Code: | export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so
exec /opt/skype/skype "$@" |
After this; skype worked fine for video but not for audio. The webcam is able to capture sound but the person receiving it; receives a very slow "motion" "darth vader" death voice sound. (we decided to use another microphone).
Putting the above code as an executable to make things easier:
| Code: | $ nano -w skype-start.sh
export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so ; exec /opt/skype/skype "$@" & |
Save, exit and make it executable:
| Code: | | $ chmod +x skype-start.sh |
Start it:
1 webcam fixed... 1 still to go

So finally some closure for 046d:0870 Logitech, Inc. QuickCam Exp
I tried a couple kernels (vanilla) and had some results
With vanilla-sources 2.6.34-rc6 i was able to start camorama the first time and have the webcam working perfectly for the first time and without any extra cmd line parameters. However that only happened one time. After that not even with extra parameters.
Worked only with:
$ camorama -d /dev/video1
Since i had other issues with that kernel i downgraded to 2.6.32.9 and after a couple tries i got it to work.
If i just try to use the cam like the above example; i get some green video image mixed with the real image.
Doing it like this works:
| Code: | | $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so mplayer tv:// -tv driver=v4l:width=352:height=292:device=/dev/video1 -fps 30 |
| Code: | | $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so camorama -d /dev/video1 |
| Code: | # dmesg
STV06xx: Probing for a stv06xx device
gspca: probing 046d:0870
STV06xx: Configuring camera
STV06xx: HDCS-1020 sensor detected
STV06xx: Initializing camera
gspca: probe ok
gspca: usb_submit_urb alt 1 err -28
gspca: no transfer endpoint found |
Problem is SOLVED
