This could be useful for our Linux desktop users. it will help you to get the screen share and video stream on your 64bitLinux desktop.
The key is use 32-bits version of JRE/JDK and Firefox
(1) install 32-bits JDK firefox.
follow https://www.2realities.com/blog/2014/10/28/webex-on-ubuntu-slash-mint-64bit/
I tried this on a 64 bit Ubuntu, it worked. I can see webex testing DEMO presentation.
or on Ubuntu you can:
sudo apt-get -y remove icedtea-7-plugin:i386 icedtea-netx:i386
sudo apt-get -y install openjdk-7-jre:i386 libxmu6:i386 icedtea-7-plugin firefox
sudo update-alternatives –set mozilla-javaplugin.so /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
(2) use VM
Or you can just create a linux 32 bits OS or windows VM on your host.
Tried the Linux Mint 32 bits VM, it worked out of the box.
for KVM ( to pass audio/sound), you may need to do this if not working out of the box:
cd
/usr/bin
sudo
mv
kvm kvm.bin
sudo
touch
kvm
sudo
chmod
+x kvm
vnc_allow_host_audio = 1
user = "your_user_name"
group = "your_user_group"
