Re: Webcam output is upside down
Have you checked Cheese Special Effects to see if "Vertical Flip" is enabled? I know it's basic, but sometimes the basic, obvious answer works.

Re: [Solved] Webcam output is upside down
after updating v4l you need to add this to your launcher "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so"
Example
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so app_name
Example
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so app_name
Re: [Solved] Webcam output is upside down
Hi,
Sorry to ask such a basic question, but I'm quite new to Mint and trying to figure out how to fix the upside-down web cam problem. I thought I'd try the suggestion made by A30N, but I am a bit confused. I open the password manager, type my password, go to settings> repositories....but here I don't see "new" or anywhere to type the url. Opening up repositories gives me a box with some options (tabs with LinuxMint software, Other Software, and Authentication), but none of the options described.
Am I just looking in the wrong place?
Many thanks for any ideas or suggestions.
Best,
Lisa

Re: [Solved] Webcam output is upside down
Hello, Lisa,
I am also new to Linux Mint and I was able to install the libraries by doing the following:
Went to update manager (the small icon of a lock that usually sits at the bottom right of your screen)
Select Edit - Software sources
Make sure the last 3 options are checked (backported packages, unstable packages and source code)
update manager will tell you that the package information is not up to date so click on the reload button.
close update manager and open package manager
on the search box type libv4. You will now find the libv4 libraries are listed there.
I don't know if I did the right thing, but I right click the libv4l-0 and libv4l-dev libraries and selected "mark for reinstallation" (since the "mark for upgrade option was grayed out). I use the 64 bit version of Linux Mint. I see there are other libraries there that are called lib32v4l-0 and lib324l-dev (I imagine they are for the 32 bit version).
After the libraries have been reinstalled, reboot your system and you will find that the camera is not upside down anymore.
Afterwards I believe you should again open the update manager and uncheck the software sources you previously checked so that you don't update those packages.
There should be an easier way to update libraries, but in the meantime this worked for me, so don't laugh at my stupid solution. I said I am completely new to Linux Mint, and so far I love it! I dual boot Mint and Windows 7 on my laptop, the two best OS's out there at this moment
Hope this helped someone!

Hi Lisa,
Sorry for not getting back to you before, and thanks for your comments Yes, Spanish is my native language.
Anyway, the webcam upside down issue has been corrected in version 9, which is awesome!

Cheese, Skype and other web cam programs all show the picture upside-down... and I tried everything that was recommended on the other threads to solve this problem, but nothing worked, in fact my whole system crushed and I had to reinstall Isadora....
Help will be much appreciated!
Thanks!

Many laptop put their webcam upside down resulting in flipped images in Ubuntu. There were fixes for some but for some you had to physically remount the camera. The webcam that comes with Lenovo Ideapad Y510 is also mounted upside down. Unluckily there wasn't any simple fix for this. (some people rotated the camera physically).
Fortunately Hans de Goede came with a beautiful solution.
Open Terminal and add libv4l ppa
Update your software listsudo add-apt-repository ppa:libv4l/ppa
Install libv4lsudo aptitude update
You have to use the following command to open any application that uses webcamsudo aptitude install libv4l-0
If you use 64 bit system, use the following commandLD_PRELOAD=/usr/lib/libv4l/v4l1compat.so application_name
For example:LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so application_name
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype
Good luck,

Re: [Solved] Webcam output is upside down
I did this: http://forums.linuxmint.com/viewtopic.php?f=18&t=57768 -> sixth post
Is there any way to set it up so that I don't have to run that command every time I want to launch Skype? Having done it once and had it work fine, it reverts to being upside-down when I launch Skype as normal, which is highly inconvenient. Help?

Re: [Solved] Webcam output is upside down
Maybe part of the solution (quoted from http://ubuntuforums.org/showthread.php?t=870681&page=2):
Thanks,

This is just way to confusing to me - can someone please tell me in simple language and in an organised way, what I need to do step by step to add a script to autostart? Only if that is the right way to do it anyway...Hum..... Well the script could look like this...
#!/bin/bash
modprobe xxxx_driver_name_xxx invert=1
In KDE there is a Autostart folder, I don't know about Gnome I bet there is. The other way of makeing it run at startup is puting it in your startup daemons. I have that "alsascript" run at startup by puting it in my daemons. I have my script to turn the brightness up in my Autostart folder in KDE because KDE starting is what turns down the brightness.
....
Anyway back to the web cam fix.... To put it in the daemons you need to... I don't know terditional Linux setup... But in BSD an Archlinux you put the script in /etc/rc.d folder and then add the name to the deamons array in /etc/rc.conf... Dose any one know what folder you list stuff to start in normal Linux???
If that dosn't work i.e. Gnome starting is what is messing it up. Then you have to put it in the Autostart folder..... Owe hay I found a grate Wiki on the Gentoo sight here is a link...
http://gentoo-wiki.com/HOWTO_Autostart_Programs
If you need root privleges to use Modeprobe then you have to give your user the ability to exicute the "webcamscript" with no password. You do this by adding this line to the sudoers file (to edit the sudoers file just type... sudo visudo)
# Same thing without a password
# %groupname ALL=(ALL) NOPASSWD: ALL
username ALL=(root) NOPASSWD: path/to/script/webcamscript
Then you have to write at new script to put into the auto start folder...
#!/bin/bash
sudo webcamscript
Check out how I did my Backlight bright on startup Workaround and I guess in is EZ to do it in Gnome to so you don't have to turn it up by hand every time you strat your computer...

Re: [Solved] Webcam output is upside down
ibm450! Yes, that helps and works in Mint 9 as well; so everytime I want to use Skype, I have to open terminal and type eg. "!2", right? Otherwise my webcam shows an upside down picture in Skype.
Thank you very much!
... now it's only the microphone I need to fix ... btw, will all these complications just vanish once Skype has a 64bit version for my 64bit computer?
Cheers!

depends on what list number your preloasd shows up on, and yes unfortunately thats what i have to do as i dont know how to create a shortcut to do this automatically, perhaps some one else would like to post?so everytime I want to use Skype, I have to open terminal and type eg. "!2", right?
but bear in mind, yours may be listed as number 34 or 100???
putting a ! in front of your history list number is like a short cut to that particular command used.
you can use the history command to list all the previous cli's used and re-execute a command by entering a ! followed by the number. the above was just a example, so in short, type history, enter and then find your preload command, take note of the number in front of it, then type ! followed by the number and enter, presto!!!

Re: [Solved] Webcam output is upside down
Thanks, I know, in my case it's !62, I just used your example too
I just read on the Skype website, that the Beta version is a 32bit one and that they are working on a 64bit version:

See also: http://blogs.skype.com/linux/2009/09/so ... tions.htmlMyth: There is a 64-bits version of skype available for download.
No, there is not yet. However, we assembled a "helper" package which will pull corresponding 32-bits libraries. This is made entirely for your convenience, so you don't have to go and hunt for these packages yourself. This brings some compatibility issues with some (especially video) libraries. Check the forum for more details.
We are working on providing a native 64-bits version of Skype.

Re: [Solved] Webcam output is upside down
i added skype shortcut to the panel
hope this helps
then right click skype icon in the panel, properties, and replace anything in the command box withright click skype icon in start menu, and select "add to panel"
for me its now working through this way instead of going through terminal, history and ! the cli linebash -c 'webcamWrapper32 skype'
hope this helps
