gspca doesn't seem to have a MAINTAINERS record. Or it is entered
under something unobvious so my search failed?
We need to fix that then, gspca is maintained by Jean-Francois Moine, with me
co-maintaining.

This is the information about the webcam given by the old gspca module, still
working with 2.6.26:

Ok, so from this I gather that you are using spcaview to watch images from the
cam. spcaview by default asks the driver for yv12 format video data.
However the vc0323 cam in your laptop delivers video data in JPEG format. The
old gspca driver did format conversion inside the kernel. Which is a very bad
thing to do and thus has been removed in the new version.
Most apps / libraries do not know how to handle the multitude of video formats
webcams can produce. For this I've written libv4l:
http://hansdegoede.livejournal.com/3636.html
Get the latest version here:
http://people.atrpms.net/~hdegoede/libv4l-0.5.1.tar.gz
Then read:
http://moinejf.free.fr/gspca_README.txt
or the included README for install instructions.
As described in the documents you can make existing applications use this lib
with an LD_PRELOAD loadable wrapper.
FOSS applications can be easily adapted to instead use the library directly, a
coordinated cross distro effort is underway to make this happen (including
pushing patches upstream), see:
http://linuxtv.org/v4lwiki/index.php/Libv4l_Progress
You can find patches for quite a few applications here. Help in patching others
is very much welcome! If you need some quick instructions what to change
exactly let me know.
Regards,
Hans
