Hi, debian-sparc. Im trying to connect logitech c170 to server. It
successfully mounted to /dev/video0, but i cant get picture. I tried to get
picture with fswebcam, and got message to syslog:

Also i tried applications: webcam and zoneminder. It dont work too. I tried
this webcam on debian amd64 and i386 and it works fine.
I have v4l on my sustem:
Frankly, I've found webcams to be very patchy on most systems,
irrespective of processor. Working from memory, I found mplayer to be
half-competent at exercising a v4l device, noting the workaround
described at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=542214
In practice, the only app I even half-trust is a much-hacked version of
the Blundel/Forrest v4lgrab. There are far too many pitfalls based on
which version of v4l a device supports, which version of v4l an app
expects, pixel format including RGB vs BGR and so on. Not to mention the
limited brightness etc. that most cheap cameras can accommodate.
