Hello Hans,
thanks for you answer. My webcam is the ASUS X5AV laptop integrated webcam. Here is the beginning of the 'lsusb -v -d 04f2:b106' command :

I am already using libv4l-0.5.8-1 (ubuntu jaunty) and tried 'LD_PRELOAD=/usr/local/lib/libv4l/v4l2convert.so skype', but it does not correct skype video vertical inversion. In Jaunty, I also have a vertically flipped image in ekiga.

Hi all,
Installing the newer v4l drivers from hg repo solved my webcam video being vertically flipped in ekiga, but not in skype, which I can not explain, as skype image seems sensible to guvcview settings (seen with guvcview --control_only). Do you have a probable explanation even if skype is non free code (I am forced to use it, working in a changing network environment, not suitable for SIP-based solutions)? Could libv4l help me to solve this problem by forcing vflip (through a hard coded patch at first, ultimately an environment variable or so, even if it is not clean enough to be included in the lib official code)? I have development skills although I do not know much about driver-level development. If you show me the way to go I can probably try a few things and hopefully get a simple solution working, at least for me, perhaps for others too...
Hi,
What sort of webcam do you have ? Are you already using libv4l ? And if so which version ?
Can you try running skype like this: LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype
?
Regards,
Hans
