Fix 64 bit Google Talk Plugin Linux
Credit for this fix belongs here but I have copied it here for ease of access
Download the 64-bit .deb from: http://www.google.com/tools/dlpage/res/talkvideo/hangouts/
Create a tmp dir:
mkdir tmp
Extract the contents of the .deb to the tmp dir:
dpkg-deb -x google-talkplugin_current_amd64.deb tmp
Extract the control files:
dpkg-deb --control google-talkplugin_current_amd64.deb tmp/DEBIAN
Fix the dependency:
sed -i "s/lib32v4l-0/libv4l-0/" tmp/DEBIAN/control
Repackage the .deb:
dpkg -b tmp google-talkplugin_current_amd64-fixed.deb
Install the fixed version:
sudo dpkg -i google-talkplugin_current_amd64-fixed.deb
