Can I get as much disassembly of the PAC7302 drivers with your comments next to
it? I am trying to improve my webcam and currently disassembling the driver, in
Vista64 with IDA Pro. (I still have the 32 bit driver files as I upgraded from
xp32)
I am helping on the gAIM/Pidgin voice/video chat and this driver isn't where I
would like it to be. I need better color balance, even after changing alot of
options I still turn out orange quite a bit.
I have Assembly expierence, I own the Intel Instruction Manuals, so figuring out
the actual given driver with a little bit of help based on the current progress
should not be difficult

Hello Christopher
Thanks for posting to linux-media@xxxxxxxxxxxxxxxx
As I wrote you back on the private mail you send me, I don't really
understand what you try to tell or ask me!
What do you mean with "disassembly"? Converting the binary Windoz drive
to assemble code? Or looking with a hex editor into the Windowz driver
and figure out what the opcode is doing?
The PAC7302 Linux driver was develop by re-engineering the Windoz drive
with the help of usb snoop. Usb snoop
(http://benoit.papillault.free.fr/usbsnoop/) is a program which can log
the usb traffic on a Windoz box. By looking at this logs, I could figure
out how to control the cam (PAC7302 bridge). To find out the compression
Pixart is using in this chip was a long journey, too.
I suggest you get the newest driver from linuxtv.org or from
Jean-Francois Moine site (http://moinejf.free.fr/).
Don't forget to get the newest libv4l lib from Hans de Geode. After you
installed this and tested the webcam, please report back how the driver
is working.
Anyway, when you are able to disassemble the Windowz drive, please post
your results here. There are some people around here how can comment
your outcome.
