Hello,

I can no more reproduce the situation where the image is upside down in ekiga and not in skype, but it occurred, and it is really weird indeed (it is now always upside-down). Maybe skype uses the driver in a odd way, like using a low level API for getting raw video data and making a part of the decoding itself? I really do not know and do not have enough v4l knowledge to figure it out... If skype does so, there is perhaps no clean solution at all. But it would be nice to try a libv4l software solution in this case, because I think the reason why the image is upside down is that ASUS just integrated the webcam upside down, so it may be found on another laptop in the right direction... What do you think?

Regards,
Florent.

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.


Ok,

So that is a uvc camera. In your original mail you wrote that the image
was no longer upside down in ekiga when you updated the kernel driver
to the hg version, but still upside down in skype, did I understand that
correctly?

Maybe there is an option in ekiga somewhere to correct and upside down
image in software and you enabled this option ?

Note that libv4l can fix the upside down image in software, but before
going there I would first like to figure out why its upside down
in some apps only thats weird. Now if it is always upside down,
things are easy to fix.

Regards,

Hans
