Public bug reported:
It looks like v4lctl cannot find the math library.
$ v4lctl show color
dlopen: /usr/lib/xawtv/flt-disor.so: undefined symbol: tan
dlopen: /usr/lib/xawtv/flt-gamma.so: undefined symbol: pow
ioctl: VIDIOC_G_STD(std=0xbfa78e6f0000005c
[PAL_G,PAL_H,PAL_I,PAL_D1,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)]):
Invalid argument

I'm under Ubuntu 11.04 and
$ apt-cache policy xawtv
xawtv:
Instalados: 3.95.dfsg.1-8.1ubuntu2
Candidato: 3.95.dfsg.1-8.1ubuntu2
Tabla de versión:
*** 3.95.dfsg.1-8.1ubuntu2 0
500 http://us.archive.ubuntu.com/ubuntu/ natty/universe i386 Packages
100 /var/lib/dpkg/status
I traced this from skype not displaying the webcam image ok, cheese either
trying to change the settings with xawtv improved the thing but was not working
as expecting graphically, finally setting directly the video parameters with
v4lctl bring this stupid link error, maybe related to #778292. In this case I
think it's priority should be a little higher than medium as it affects a large
range of package including webcam that is a master piece o user adoption of
Ubuntu by lambda user.
