Image on webcam is upside-down

[Bazilio]

I am russian, so sorry for my english.

My system is Kubuntu 7.10
bazilio@ASUSG1S:~$ lsb_release -rd
Description: Ubuntu 7.10
Release: 7.10

I use Asus G1S laptop and i have a problem with my webcam.
It works out of box, but image is upside-down.
In kopete settings it works, but upside-down
In skype it works, but upside-down.

I know that it old bug, but nobody can solve it.

Some info:
bazilio@ASUSG1S:~$ lsmod | grep video
video 18060 0
uvcvideo 57480 0
compat_ioctl32 2304 1 uvcvideo
videodev 29312 1 uvcvideo

v4l2_common 18432 2 uvcvideo,videodev
usbcore 138632 7 xpad,uvcvideo,hci_usb,usbhid,ehci_hcd,uhci_hcd

String with "syntek" about my webcam:
bazilio@ASUSG1S:~$ lsusb

Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000

In windows system it works perfect, webcam detects as D-Max_GD-5A35, device PID code: USB\VID_174F&PID_5A35

In linux it detects as Sonix Technoogy Co., Ltd USB 2.0 Camera

P.S. sorry, if i wrote in wrong place.

This is bug that is coming since 7.04, was present in 7.10 too and continues in 8.04 Beta.
I tried a fresh install here of Kubuntu 8.04 Beta KDE4 and the problem is still present.

I also tried to adjust the camera through luvcview, without success too.
That was described in http://asusg1s.wikidot.com

Also, until now I could not get my bluetooth up in 8.04 (was working in 7.10)...

I have the same problem with a Syntek webcam (in a Packard Bell EasyNote MX66-205). The device ID in my case is 174f:a821.

Here' s a workaround:

1/ Temporarily flip the image (until reboot):

$ echo 1 > /sys/class/video4linux/video0/vflip

Or you can try:

$ sudo rmmod stkxx11
$ sudo modprobe stkxx11 vflip=1

2/ Permanent solution:

 (1) sudoedit /etc/modprobe.d/stk11d
 (2) paste the following line in that file:

      options stk11xx vflip=1

 (3) reload the kernel module

     sudo rmmod stkxx11; sudo modprobe stk11xx

Hope this helps!

Oops, I found a bunch of typos in my last comment. I misspelled the driver module name a few times. Here's a corrected version, please ignore the previous one. Apologies for the inconvenience...

[Bazilio (bazilio-recast1)]

bertvv, thank you for reply.
but my webcam uses uvcvideo instead of stk11xx
and sudo modprobe stk11xx vflip=1 does nothing.

[Bert Van Vreckem (bert-vanvreckem)]

Okay. Does the first part of method 1 work ("echo 1 > ..." etc.)?

If so, you could try to replace stk11xx by uvcvideo in method 2 and see how that works. I tried to find documentation on the available options of the uvcvideo kernel module, but couldn't find much. So, I don't know if the vflip option is available for your driver.

Maybe you should contact the developers of the uvcvideo driver at http://developer.berlios.de/projects/linux-uvc/

[Bazilio (bazilio-recast1)]

No, ("echo 1 > ..." etc.) not work

bazilio@bazilio-laptop:~$ ls /sys/class/video4linux/video0/
dev device name power subsystem uevent

there is no "vflip"

There is my bug with no reaction:
http://developer.berlios.de/bugs/?func=detailbug&bug_id=13439&group_id=5681

http://linux-uvc.berlios.de/#footnote-3
There written:
"This camera module is known to be mounted upside-down in some notebooks. There is currently no documented way to rotate the image at the device level. If you don't mind holding your computer upside-down, the camera should work fine."

But other people can do (echo 1 > /sys/class/video4linux/video0/vflip) and all ok. Why I cant't? Where is my vflip?
Maybe bug in video4linux?

[Bert Van Vreckem (bert-vanvreckem)]

This depends on the driver/kernel module, in your case uvcvideo (in my case stk11xx). The developers of uvcvideo apparently haven't implemented this option, those working on the driver I use have. I guess you're stuck...

[Daniel T Chen (crimsun)]

Is this symptom still reproducible in 9.04 with linux-image-2.6.28-2-ub-generic?

[Bazilio (bazilio-recast1)]

Now i'm using Kubuntu 8.04.1. I do not have the opportunity to install the system from Alternate install CD. Is there a Live CD, so I can try the system without installing? I use my laptop for work and do not want to risk.

[joiner (gaffajoiner)]

Go hear and download it, i got one on disk sent by them, it a great
program, trying to learn how to use it properly

Hi, i'm marking this as dupe from bug #224559

Thanks for your report.

Hi

I am Kapil Soni. I have installed ubuntu 11.4 version, which is going great but I am facing the same problem. When I use the webcam it shows me upside down. And I am really very upset with this. Can you please solve this bug.
