[EN] Integrated camera shows image upside down

[davidb]

Hi,

Usually my camera just worked fine but I havent used my camera for quite a while. Now I wanted to skype with someone and my the picture is shown upside down. In all other applications I checked, it is the same behaviour.
Googeling this problem showed some solutions for ASUS camera (preloading v4l1compat.so) but it doesn't work for me and neither do I want to start all camera using applications from terminal.


The problem seems to be, that the driver mounts the camera upside down. Can this be changed somehow? Or does anyone know the solution to this problem?


My Laptop is a Lenovo E530


Thanks for the Help
David

hi davidb,

there is a longer thread with comments in this issue here: http://community.linuxmint.com/tutorial/view/219
note that there are multiple locations / paths for the library mentioned, you might need to verify its location on your system, or install the lib first.
please, also provide further info on your system (32/64 bit, etc.)

Hi!

I have the lib installed and double checked the path. Also I installed v4l2ucp and tried to rotate the cam picture. Still upside down.
I have a 64 bit system. The solution neither works with the 64 bit lib nor the 32bit (skype).

A few infos:

With guvcview I can flip and mirror the picture. I tried to load the saved settings with uvcdynctrl but it seems to have no effect. Am I missing something?

I have an old Logitech USB camera that also doesn't work correctly with skype, out of the box.  I have no idea whether the script that I use to launch skype will be of any help for your hardware, but I will share it just on the chance.  This is my skypelauncher.sh script:

Code: [Select]

#!/bin/sh
export XLIB_SKIP_ARGB_VISUALS=1
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so
env PULSE_LATENCY_MSEC=60 skype %U
exit 0
