Asus K52F laptop web camera shows upside-down picture in Skype

Question

How to fix upside-down picture produced by web camera in Asus K52F (1.3 Mpix, don't know the model) laptop (Intel i3 M350, Intel video, Ubuntu 10.10) ?

Update: It seems ridiculous :) but the "upside-down issue" is continuing even in Ubuntu 11.10. I am pretty sure it's a Skype prob (2.2.0.35 beta from official Ubuntu partner repository.)

Solution 1

Quoting Hans de Goede:

Hi,

Try using the latest libv4l which has a (constantly updated) list of know to have an upside down webcam laptop models. Installation instructions are here: http://radu.cotescu.com/2009/11/05/flipped-images-ubuntu-webcam/

If that does not work your laptop model is not in the list of libv4l, please do (as root):

lsusb > lsusb.log
dmidecode > dmi.log

And send me <[email protected]>, a mail with the 2 generated files attached. Do NOT copy and paste them I need them 100% unmodified.

I'll then add your laptop to libv4l's upside down table and get back to you with testing instructions.

Regards,

Hans

You can see here, that your laptop model has been added to the the latest version of libv4l.

Now you either need to test it (instructions in above link), or wait for Ubuntu to update that package (which, I guess, won't happen for Ubuntu 10.10).

Solution 2

Check whether the procedure described here works for your case:

Solution 3

My laptop is the same as yours. I followed htorque's solution, the only difference is that when you call skype the command LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype doesn't work because the folders are different.

Using the following instead I can see the webcam in the right mode:

LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype

The following command set has helped: sudo add-apt-repository ppa:libv4l/ppa && sudo apt-get update && sudo apt-get upgrade. Yet, it works only in Cheese. Skype continue to show a flipped picture.

You should try using your laptop upside-down :D J/K ...lol

Sometimes I do :)

for me this solution here worked ubuntuforums.org/showpost.php?p=8925031&postcount=225 , the only thing I had to change was location of v4l1compat.so library because on my Ubuntu 11.10 it is in /usr/lib/i386-linux-gnu/libv4l/, to check where it is on your computer type locate libv4l in terminal

It refers to 2008-generations of Ubuntu, so I think there should be easier way to fix such a problem in 2010 :)

Hi Owais, thanks for the hint. Preview in v3l2ucp works well, Skype continues showing flipped picture :)

@Vincenzo Sometimes with hardware problems the solution will always take some degree of work. I'd recommend still giving it a shot and see if it helps.
