[gentoo-user] Webcam ? Help me please...

[meino.cramer]

 
Hi,

To watch some birds I have bought a Logitech QuickCam Pro For
Notebooks WebCam.

I have configurted the kernel for UVC and compiled a driver 
as modulem which is stated to support my Cam.

...the only thing I need is an application to make 
the video visible and which allows me to save the 
video and an application to control the
cameras features.

I found "zoneminder" which is masked due to security issues 
and which neeed A LOT more things to support features I wont
use (PHP, MySQL...).

I qsearched for web cam (not match) and other keywords without
success.

A hint, what to install would be very helpful and heartly
welcome!

Have a nice weekend!
Kind regards,
Meino Cramer

I use "cheese", which let you take photos and videos. Under the menu
"Edit/Preferences" I can customize the resolution.

Hi Manuel.

sounds good! Thanks for the hint. But,....


I installed cheese without complains of the compile process.
But starting cheese produces:

    solfire:/home/mccramer>cheese
    cheese: error while loading shared libraries: libplc4.so.7: cannot open shared object file: No such file or directory

And ldd /usr/bin/cheese produces beside other things:

        libplc4.so.7 => not found
        libplds4.so.7 => not found
        libnspr4.so.7 => not found
        libplc4.so.7 => not found
        libplds4.so.7 => not found
        libnspr4.so.7 => not found
        libplc4.so.7 => not found
        libplds4.so.7 => not found
        libnspr4.so.7 => not found
        libplc4.so.7 => not found
        libplds4.so.7 => not found
        libnspr4.so.7 => not found


Further investigations shows, that instead the *7* version of
that libs the *8* versions are installed on my box?

qsearch libplc
or
qsearch plc


doesnt produce anything meaningful.

/usr/lib/nspr, where libplc is located, is in /etc/ld.so.conf.

Lost?

It's really strange....may be that revdep-rebuild can help you.

http://www.gentoo.org/doc/en/gentoolkit.xml#doc_chap4

Try to execute it in pretend mode (with the flag --pretend) and see if
it discovers some broken packages.

Hi,

ok, revdep-rebuild and re-emerge of nss/nspr does the thing...now I
can see through my webcam.

BUT:
Max. resolution is 176x144 in vido mode (nothing more offered via
"preferences")
Is it all I can exspect from a Logitech Quickcam Pro for Notebooks?

Furthermore: The autofocus seems to be off - the image is blurry...

Is there any other trick I should know?

Thanks again for any help in advance!
Meino

Hi,

Thank you for the hint. The programm says "unable to capture image".
Executing it as root does the same.

ffmpeg could capture a video stream from my webcam, so the cam is not 
the problem...

Lost?

Very strange.

Have you tried good old mplayer ? It can play the stream from your
webcam just fine and it's very configurable.
See:

(first google hit)

Hmmmm...tried that, but cannot tweak the resolution above 176x144...
That is VERY small...

The resolution given in the commandline is for the output device
(software scaled)...

Nay idea how to do this with mplayer?

M.  (also :)
