[SOLVED] Webcam image fliped (uvcvideo module)

M1zut4m4 · 2009-08-07 11:36:18

Currently on my new Japanese Computer ASUS N10J (eeepc like + 9300m GS) the webcam is mounted flipped (thanks engineers ).
So the only way to unflip is to rewrite a part of the module uvcvideo...

googling, I've found this interesting topic
http://forum.notebookreview.com/showthr … 810#kernel
providing the source code for the holy module
http://allurgroceries.is-a-chef.com/n10/uvc_video.c

BUT I still have a problem :
How to integrate it to my ArchLinux distro/kernel (compilation should be ok but after...) ?

It seems to have a out of date aur package doing this tuff so, I'm ready to maintain a new package for people having the same trouble (if it's not too long) but before, please teach me how to do, currently I don't have so much time for RTFM

Help needed !!!!
有り難う御座います♪♪♪

ps : sorry for my English ><, 本当に済みません
pps : no, I'm French

Well if you are a master student Computer Science you should know how to RTFW:P. Where is the AUr package located ? If you give us a link we could help you out.

Yes, But I try ^^

#man uvc
No manual entry for uvc
// I also try this
#man woman
No manual entry for woman

But thanks I didn't know the RTF"W" (here there still are computer science & embedded robotic system (yes, I saw embedded winXP laptop in robot ) student who code under windows without knowing what is a command line)

Where is the AUr package located ? If you give us a link we could help you out.

Linux 2.6.26 and newer includes the Linux UVC driver natively. You will not need to download the driver sources manually unless you want to test a newer version or help with development.

The uvcvideo driver for kernel26 2.6.25 patched to flip the video.

Could you do " lsmod | grep uvc ". there should be some video module already in the kernel modprobe it and test the webcam. The webcam software should flip the image.

good luck

Yes but currently it didn't flip my webcam or I Have to found the function/flag to activate somewhere to flip the video if a such function/flag exists...

Hi all, (uh Jelly in fact )

So to solve the problem, there is a pseudo automatic solution
You just need to send an e-mail to Hans de Goede (libv4l developer) and He will add your webcam id to a special list to flip upside down automatically your webcam

You need to be registered (free) to the mailing list to send an email...
All you need at this address -> https://lists.berlios.de/pipermail/linu … 04886.html

Yes I know this method is specific for each one but no many people have this problem, so currently libv4l team has decided to solve the problem like this....

work fine for vlc & skype

Bye all

Congrats that you got it working

Would you like to write a nice wiki for this webcam, so new users don't have to look into this thread??
