In the README file the first installation method needs
a reminder at the end, to start gspca_hlp as root
(very green picture with spcaview otherwise - yes I
forgot a few times).

The following formats are reported with gspca_hlp

$ v4l-info /dev/video1 | grep pixelformat
ioctl VIDIOCGTUNER: Invalid argument
ioctl VIDIOCGAUDIO: Invalid argument
ioctl VIDIOCGFBUF: Invalid argument
        pixelformat             : 0x31384142 [BA81]
        pixelformat             : 0x56595559 [YUYV]
        pixelformat             : 0x32315559 [YU12]
        pixelformat             : 0x33424752 [RGB3]
        pixelformat             : 0x33524742 [BGR3]
        fmt.pix.pixelformat     : 0x31384142 [BA81]

I can't see the YUV420 or RGB24 you mention - I'm
confused, is this correct?

However spcaview now produces a good picture - well it
has the same overexposure problem as gspcav1, so the
picture is acceptable indoors. e.g.
$spcaview -d /dev/video1 -t

The bad news is that my PC locks up completely if I
use the command
$spcaview -d /dev/video1 -t -g

I do not have the knowledge to diagnose what happened
in detail - screen locks and no reponse at all from
the keyboard or mouse.  It only happens if gspca_hlp
is running. Let me know what other info you need.

Your vlc command works here - same good picture as
$vlc v4l:/dev/video1

None of the formats listed above by v4l-info are
listed as supported by mplayer - but as before
entering the hex values has some success:

0x31384142 [BA81] = fails mplayer shuts down.
0x56595559 [YUYV] = as before lots of pink
0x32315559 [YU12] = mplayer stops with a Segmentation
0x33424752 [RGB3] = Picture OK (overexposed)
0x33524742 [BGR3] = Picture OK (overexposed).
