Logitech Quickcam pro for laptop on FC4

_UnPrEdictAbLe_ · 08-19-2005, 05:07 AM

Hi,
I am using a Logitech Quickcam Pro for Laptops on Fedora Core 4. Earlier when I had Fedora Core 2, it worked fine in xawtv and gnomemeeting (in kernel 2.6.10).

In Fedora Core 4, it doesn't detect the CAM correctly. The gnomemeeting wizard is able to capture the audio from the cam but is unable to capture the video, and sometimes fails to detect. I installed kernel kernel-2.6.10-1.771_FC2 and tried to make it work there.

xawtv gives the following error.
[anurag@localhost ~]$ xawtv
This is xawtv-3.94, running on Linux/i686 (2.6.10-1.771_FC2)
Cannot open plugin directory /usr/lib/libquicktime
Did you forget "make install"? You need it because
libquicktime cannot load plugins out of the sourcetree
/dev/video0 [v4l]: no overlay support
v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=7): Invalid argument

and a complete black video and when I close the window,
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=5): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=4): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=1): Invalid argument
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=13): Invalid argument

Is it most probably a kernel problem. I have used different CAMs of the same type to rule out any "hardware faults". Please help me.

Hello,

I am facing same problem. My xawtv worked fine in Fedora 3 but after shifting to Fedora 4, nothing works. I uninstalled xawtv and tried to reinstall it but it gives me compilation error.
If you want to stream from webcam only you can try this thing

Instal pwc driver pwc-10.0.7a.tar.bz2 found from http://www.saillard.org/linux/pwc/files/
($ ./configure
$ make
$ make install )
and download camstream application . Things should work out fine

btw, i searched a bit and found in some forum about reason behing the error you are getting
ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=5): Invalid argument

It says that pwcsx handles bigger framesize grabbing. you get this error when your driver are unable to handle bigger framesize. I have tried changing height and width of framesize less than 100 but things dont work. Since pwcx is no longer supported due to GPL in recent kernel, this could happen

Hi,

I got it working quite long back. Sorry, I didn't post a reply here. I posted it in the "success stories".

You can see it here.. http://www.linuxquestions.org/questi...hreadid=359294

Hello,

i got it working using this link only. but still i cant get xawtv installed in fedora 4. i am getting following error message while issuing make

Code:

Well, you should not try MAKE and MAKE INSTALL. I think a much much better alternative is to install the RPM. Go to www.pbone.net or www.rpmfind.net and install it.

Another software, much better than xawtv is "camstream". I am using that one now. Try to get that one.

You can set up your YUM correctly and just do,
yum install camstream

to get things working.

Here is a link to set up YUM.
