xawtv 'webcam' & uvcvideo webcam: ioctl error
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 grabber config: size 320x240 [16 bit YUV 4:2:2 (packed, YUYV)] input Camera 1, norm (null), jpeg quality 75 rotate=0, top=0, left=0, bottom=240, right=320 write config [ftp]: local transfer ~/Desktop/uploading.jpeg => ~/Desktop/webcam.jpeg ioctl: VIDIOC_DQBUF(index=0;type=VIDEO_CAPTURE;bytesused=0;flags=0x0 [];field=ANY;;timecode.type=0;timecode.flags=0;timecode.frames=0;timecode.seconds=0;timecode.minutes=0;timecode.hours=0;timecode.userbits="";sequence=0;memory=unknown): Invalid argument capturing image failed
Any ideas what is going wrong here?
TIA

I think I do, xawtv contains a few v4l2 handling bugs. This patch fixes them and most likely fixes your issue:
http://cvs.fedoraproject.org/viewvc/devel/xawtv/xawtv-3.95-fixes.patch?revision=1.1

Thanks, Hans. I downloaded and applied that patch to the source. However when I go to compile it, 'make' returns an error:
[...]console/fs.h:2:20: error: FSlib.h: No such file or directory

It looks like a file called fslib.h is missing. Neither yum nor Google turn up a package by this name, although there are a couple of references on the Web to this file. Any idea what I am missing?

Well these errors are completely unrelated from the patch I've send you. xawtv has been unmaintained upstream for a while, so you want to start with the sources as provided by your distro, not with an pristine upstream tarbal.

Hans
