[patch] USB video support in KDE4 + sane + more under FreeBSD

[Hans Petter Selasky]

Hi,

I was compiling the latest version of KDE4 on my box and I noticed it picked up my installed libv4l2. 
The only problem is that you need some patches before everything is compiling :-)

About libv4lX on FreeBSD, please see:

http://lists.freebsd.org/pipermail/freebsd-emulation/2009-June/006231.html

Only USB webcams supported yet.

After installation manually add -lv4lxdrivers to all the libv4l*.pc files!
I will try to get this included into my ulinux distribution soon.

Before:
Libs: -L${libdir} -lv4lconvert
After:
Libs: -L${libdir} -lv4lconvert -lv4lxdrivers

/usr/local/lib/pkgconfig/libv4lconvert.pc
/usr/local/lib/pkgconfig/libv4l2.pc
/usr/local/lib/pkgconfig/libv4l1.pc

Then patch KDE4 like this:

And don't forget to chown /dev/usb/X.Y.* [webcam USB device] to the user running the webcam application.
