Linux – Skype webcam upside down but v4l1compat missing

cameralinux-mintskype

I am running Linux Mint, but i think this issue will be mutual with Ubuntu. My webcam in Skype is upside down (in Cheese it's ok). There are a lot of topics dealing with this coming up with fix like this:

$ LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so skype

or similar modifications. Unfortunately, I don't have this file.

$ locate v4l1compat.so

outputs only:

/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so

which doesn't work:

$ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so skype
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.

Skype loads, but the webcam is still upside down.

I remember I've read somewhere that I should use 32bit libraries because of skype. But how can I get those? I tried simple copy from another Linux machine, but that unsurprisingly did not help.

Dependency search for libv4l-0:i386

$ aptitude why libv4l-0:i386
i   ia32-libs                       Depends  ia32-libs-multiarch       
i A ia32-libs-multiarch:i386        Provides ia32-libs-multiarch
i A ia32-libs-multiarch:i386        Depends  gstreamer0.10-plugins-good:i386
i A gstreamer0.10-plugins-good:i386 Depends  libv4l-0:i386 (>= 0.5.0)

To get libv4l-0:i386

$sudo apt-get install ia32-libs

That will include /usr/lib/i386-linux-gnu/libv4l/v4l1compat.so

Skype missing GPG key

See here how to install Skype on Scientific 6. Basically, you shouldn't do the check by yourself.

I will outline the steps here:

# yum install alsa-lib.i686 dbus-libs.i686 e2fsprogs-libs.i686 expat.i686 fontconfig.i686 freetype.i686 glib2.i686 glibc.i686 keyutils-libs.i686 krb5-libs.i686 libcap.i686 libgcc.i686 libICE.i686 libpng.i686 libselinux.i686 libSM.i686 libstdc++.i686 libX11.i686 libXau.i686 libxcb.i686 libXcursor.i686 libXdmcp.i686 libXext.i686 libXfixes.i686 libXi.i686 libXinerama.i686 libXrandr.i686 libXrender.i686 libXScrnSaver.i686 libXv.i686 openssl.i686 qt.i686 qt-x11.i686 zlib.i686
# gedit /etc/yum.repos.d/skype.repo

In the file above you basically post the following:

[skype]
name=Skype Repository
baseurl=http://download.skype.com/linux/repos/fedora/updates/i586/
enabled=1
gpgkey=http://www.skype.com/products/skype/linux/rpm-public-key.asc
gpgcheck=0

# yum install skype
# chmod a+x /usr/bin/skype

If you have problems with Video Chat do the following:

# mv /usr/bin/skype /usr/bin/skype.proper
# cat << EOF > /usr/bin/skype
#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
skype.proper
EOF

The old Skype executable has been renamed skype.proper.

UPDATE:

i have done some Google research about the GPG key for skype, but no one seems to have it, as you can see here and here (at the skype forums), and here too, and here is the Google page with the search i have done and it full with complains about the missing key.

I would recommend, to install Skype with either the instructions above, or to download it directly from the skype website here.

Skype doesn’t work with webcam A4Tech PK-130MG

The link you refer deals with 32-bit libraries to support video in Skype. This is not your problem, yet.

According to this discussion it seems that your webcam is supported by GSPCA driver. Nevertheless you have to provide some more information related to issue:
uname -a # I don't even know if your system is 64-bit or 32-bit.
lsusb # I suppose your camera is usb from a picture. lsmod|grep gspca # To make sure if the GSPCA driver is loaded.

You might also have a look at Mandriva QC guide. Even thou is different distro and different webcam it provides some useful information.
