That looks like the stderr of /usr/bin/v4lctl that gets echoed to the
console. This is the output of a Digital HDTV TV capture card I'm using
(which only has one analog input) :

bash$ v4lctl list -c /dev/video0 1> /dev/null
ioctl: VIDIOC_G_TUNER(index=0;name="";type=unknown;capability=0x0
[];rangelow=0;rangehigh=0;rxsubchans=0x0 [];audmode=MONO;signal=0;afc=0):
Invalid argument
config: invalid value for input: Television
valid choices for "input": "Composite0"

I'm not sure why there is a difference, I just checked out a newer version
of vic from CVS before building the new RPM snapshot.

Notice the "invalid value for input: (null)" stderr output from
/usr/bin/v4lctl. I think the corresponding V4L2 driver (the bttv driver?)
needs some minor mods in the source code to indicate the inputs that
particular model of Osprey capture card has, currently all the inputs on
that card don't have a name.


Cheers,
Doug
