Webcam image vertical flip

Postby Stepan on Fri Jan 11, 2013 3:47 pm

I use my webcam fixed upside down above the table - for me it's just more comfortable. Of course now there's a problem to flip the image upside down. In Windows that can be easily performed by Skype settings. In Linux Skype there are no such settings and the only way to flip the cam Guvcview is supposed to be - but its settings affect nothing but it itself.
So I need to know if there's any software or driver setting to flip my webcam image globally for all applications and websites.
Thanks in advance.

None of those solutions work in my case. At least because from the beginning I've had normal camera image. I just flipped the camera myself physically and need to make it inverted (to make it like all those people have as a problem)!!

Best solution.... position your webcam is it should be :wink: But that will have a negative effect on your comfort.

But take a look here: http://ubuntuforums.org/showthread.php?t=838210. On launchpad somebody had also such an issue and for that user the solution in this linked helped solving his problem.

And there's another website proving a possible solution: http://radu.cotescu.com/flipped-images-ubuntu-webcam/.

You did tried this: http://superuser.com/questions/201439/h ... video-chat ??

The last solution would be nice if I had Skype of version above 4, but Linux doesn't have such. Other solutions don't fit to me.

Yes, there is: http://www.omgubuntu.co.uk/2012/11/skyp ... gin-screen

And available on the site of Skype too: http://www.skype.com/intl/en/get-skype/ ... ter/linux/

I hope you're not so lazy that you didn't search for it yourself??? Especially when you can the latest version of Skype on the Skype website itself....

That's the very problem that Linux has only Skype 4.1 but not version 6 or higher where the vertical flip option is. Version 4.1 doesn't have webcam flip option.

This command helps to flip the camera in Skype when typed in Terminal:

Code: Select all
export LIBV4LCONTROL_FLAGS=2 && LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype


So the latest question is how to make it work for all software and execute automatically?

I didn't get any results with this command. There is no "lib32" in my user directory either..

Is there any other way to vertically flip the webcam image in skype?

lib32 is there on 64-bit systems. If yours is 32-bit, try the same command with just lib instead of lib32.

I found the right file, I had to use this:
Code: Select all
export LIBV4LCONTROL_FLAGS=2 && LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so skype


But the image is still mirrored. (I suppose it will also appear mirrored to the person I call, too..)
