At the step concerning enabling epel, simply go to /etc/yum.repos.d/ and enable the epel repo.

At the end, sudo to root and create a password for the opc user.

Step 3: Install xrdp-sink

Follow the instruction at https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/Build-on-CentOS-7.x

Step 4: Install IMEs

Play octoshape stream on windows with VLC player

Install windows octoshape plugin at http://www.octoshape.com/files/octosetup.exe Install VLC player at http://www.videolan.org/vlc/download-windows.html . Use the installer so later octoshape can pick it as the preferred player. (Updated 12/26/2010: A dirty way to make sure windows associate all media files to vlc player is to explicitly set in vlc's Tool -> Preferences -> Interface -> Set up associations, select all file types. Then in Octoshape Settings (right click on the Octoshape system tray icon and select Settings), select use "System player") Create a bat file named stream.bat. In Windows XP, type in the bat file.
