Webcam and Skype

#1 Post by jsajczuk »

my netbook webcam works with the following and Skype 2.0 but doesn't work with Lucid Puppy 5.x:

windows xp, eeeubuntu 3.0 standard, eeebuntu 3.0 nbr but these version are turtle slow compared to using Lucid Puppy.

in Lucid Puppy, when I use options->video then test, the webcam light comes on but the preview box goes grey.

Any ideas cause I really prefer Lucid Puppy over the others.

It seems it's quite hard to get skype video working in puppy... I'm having the same problem, and didn't find a solution yet Camera works in camstream software, but not in skype.

Try this, perhaps it works for you:

skype camera works solution it works

#3 Post by Sezar »

I tried to see my old cif q-tech webcam video with skype v2 on puppy 528. It works with Guvcview app. but not with skype and now I have solution for newbie like me:

1. instal this pet v4l-utils-0.8.5-x-wary53.pet from : http://www.murga-linux.com/puppy/viewtopic.php?t=83569

2. reboot

3. make sure , that you have now this folder v4l1 in lib with these files:

/usr/lib/libv4l/v4l1compat.so

and

/usr/lib/libv4l/v4l2convert.so


3. open menu - utility - PupMenu application launcher

4. click on Internet field and choose Skype than clic on edit selected app (last icon on right from skype field) .

5. In Geany editor change this line with this:

Code: Select all

Exec=bash -c 'export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so; skype'
save it!

6. reboot

7. done, start skype from menu-internet-skype and try video in option or try videocall

you can try the other file if skype still no has webcam video

Code: Select all

Exec=bash -c 'export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so; skype'
for me it helped for this Q-tec 100 webcam and for playstation2 black old eye toy web cam too, with functional microphone also ! I can skype with video with puppy 528 now!!!! great I love puppy, thanks !

hope it will help someone... sorry my english :wink: [/img]

v4l-utils for webcams and skype

#4 Post by watchdog »

I had the job just done in a my install of lupu528_005 and so I can help you. I have compiled v4l-utils in lupu even if it's reported the wary version working in lupu, too. Install the attached pet. With some webcams you have to run skype by a console command of the kind:

Code: Select all

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
or

Code: Select all

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype
I don't have tested the packaging with new2dir command: in my install I directly installed from source code. So report your testing.

control settings

#5 Post by Sezar »

Great, it works, can you compile V4L2UCP ,an universal control panel for V4L and V4L2 devices for 528? It woud be great. My eyetoy webcam and Logitech need set brightness , contrast, saturation etc and change resolution.... With guvcview some settings works but with skype no changes. How to set webcamera settings or in which file for skype are these settings in puppy.... I think v4l2ucp can do the trick.
I tried to edit .guvcviewrc and default.gpfl but no changes for skype:

http://guvcview.sourceforge.net/Doc.html

I only found this , but I donť understand , how to make v4l2ucp work:

With deb2pet I obtained a pet package of multimedia debian v4l2ucp that works in every puppy. Only in slacko 5.5 it needs qt-3.3.8 from puppy3 repository and a symbolic link named libqt-mt.so.3 in /usr/lib to /usr/lib/qt-3.3.8/lib/libqt-mt.so.3.3.8:

Code: Select all

ln -s /usr/lib/qt-3.3.8/lib/libqt-mt.so.3.3.8 /usr/lib/libqt-mt.so.3
About lupu I had not to do this but consider that I usually install qt-3.3.8 in my puppies.

This has not a menu entry, so in console type:

Code: Select all

v4l2ucp
In lupu I have a more evolute v4l2ucp from ubuntu old ppa which should work:

ok, in puppy 528, i downloaded your link for v4l2ucp, than it wanted qt-3.3.8.pet and than this

Code: Select all

ln -s /usr/lib/qt-3.3.8/lib/libqt-mt.so.3.3.8 /usr/lib/libqt-mt.so.3
and than (error while loading shared libraries: libpng.so.3: cannot open shared object file: No such file or directory) more this:

Code: Select all

ln -s /lib/libpng12.so.0.42.0 /lib/libpng.so.3


it works now thanks, but one problem with eyetoy cam. I tried skype, I have test skype picture colors very/only blue , no red, and I need correct it. In GUVCVviewer the same cam in 320x240 has the same problem , when I switch to 640x480 the picture is perfect...
ok, but in skype , in guvcvviewer or in v4lucp i can correct only brightness, contrast and color for this cam, nothing like resolution, gamma, saturation......
any ideas how to do it. It use ov519 driver. But why it works with 640x480 and with 320x240(which use skype) not???

images attached...

Try another frugal install and install the v4l2ucp at the second link I gave you in the previous post from ubuntu old ppa: it's more evolute in lucid, it should work without symbolic links and it has a menu entry.

ok, the 2 installation pacage v4l2ucp v.202 deb file wants this:

v4l2ucp: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

where to find it? I have only this link

http://www.murga-linux.com/puppy/viewtopic.php?t=68535

but I dont want install all these pets i think it has 32MB......

I tried to run this webcam eyetoy on my lubuntu 13.4 with v4l2ucp version 202 (the same) and it works but I have only Brightness and Color. But 320x240 picture is normal there... :roll:

I think it must exist some file to edit these settings without any other programm, lib. no?

You need qt4 which you can get as sfs. I use qt-4.7.1:

https://docs.google.com/file/d/0B9iMb4U ... sp=sharing

The official thread for qt4 libraries is:

http://www.murga-linux.com/puppy/viewtopic.php?p=530822

I have also used:

http://distro.ibiblio.org/puppylinux/pe ... -4.7.3.sfs

I suggest my first link to qt-4.7.1.
With qt4 sfs loaded the v4l2ucp from ubuntu should work.

EDIT: now released
