Hello,
I'm working on an old driver called qcamvc for Connectix QuickCam VC
webcams
(parallel port and USB models), found here:
http://sourceforge.net/projects/usb-quickcam-vc/
Luckily, it was modified last year to compile with 3.x kernels.
After trivial modification (mfr and model), it works with parallel-port
QuickCam Pro (sort of - only at 320x240 and with vertical lines on the left
and blank part at the top). I don't have QuickCam VC (yet).
After removing a lot of code (it's now around 1200 [main] + 660 [parallel] +
320 [usb] lines), one problem still remains: in-kernel colour conversion with
software contrast, hue, saturation and gamma.
According to comments in the code, the camera sensor seems to have a CMYG
filter, like no other linux-supported camera. So the proper way to support
these cameras is to introduce a new pixel format, move the conversion to
libv4lconvert and remove all controls not provided by hardware?
Correct.
Regards,
Hans
