Thank you for your interest in CasparCG Server, a professional software used to play out and record professional graphics, audio and video to multiple outputs. CasparCG Server has been in 24/7 broadcast production since 2006.

The CasparCG Server works on Windows and Linux.

• A graphics card (GPU) capable of OpenGL 4.5 is required.
• An Nvidia GPU is recommended, but other GPU's will likely work fine.
• Intel and AMD CPU's have been tested and are known to work
• PCIE bandwidth is important between your GPU and CPU, as well as Decklink and CPU. Avoid chipset lanes when possible.

• Windows 11 is recommended
• Windows 10 is supported as best effort

• Ubuntu 24.04 is recommended
• Other distributions and releases will work but you will need to compile it yourself and have not been tested

1. Download a release from (http://casparcg.com/downloads). Alternatively, newer testing versions can be downloaded from (http://builds.casparcg.com) or built from source

2. Install any optional non-GPL modules

   • Flash template support (Windows only):

   1. Uninstall any previous version of the Adobe Flash Player using this file: (http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe)

   2. Download and unpack (http://download.macromedia.com/pub/flashplayer/installers/archive/fp_11.8.800.94_archive.zip)

   3. Install Adobe Flash Player 11.8.800.94 from the unpacked archive: fp_11.8.800.94_archive\11_8_r800_94\flashplayer11_8r800_94_winax.exe

3. Configure the server by editing the self-documented "casparcg.config" file in a text editor.

4. 1. Windows: start casparcg_auto_restart.bat, or casparcg.exe and scanner.exe separately.
   2. Linux: start the run.sh program or use tools/linux/start_docker.sh to run within docker (documentation is at the top of the file).

5. Connect to the Server from a client software, such as the "CasparCG Client" which is available as a separate download.
