Subject: xawtv 'webcam' & uvcvideo webcam: ioctl error
Date: Mon, 03 Nov 2008 17:30:40 +0100	[thread overview]
Message-ID: <490F2730.9090703@lim.nl> (raw)

Hi all,

I am trying to get the 'webcam' utility of xwatv working with my uvcvide 
webcam, a Creative Optia. My Fedora 9 system recognizes the webcam fine; 
here is the dmesg line:

uvcvideo: Found UVC 1.00 device Live! Cam Optia (041e:4057)

The webcam works with apps like Skype.

I'd like to configure it to upload images periodically to my website 
using the xawtv 'webcam' utility. I create ~/.webcamrc as indicated in 
the man page, but when I run it, it return an error message:

$ webcam
reading config file: /home/colin/.webcamrc
video4linux webcam v1.5 - (c) 1998-2002 Gerd Knorr

write config [ftp]:

Invalid argument

Any ideas what is going wrong here?

TIA
