CasparCG is a professional graphics and video play-out software, proven in 24/7 broadcasts since 2006. All files can also be downloaded from the SourceForge download page. Templates and Source files for the tutorial “Creating Dynamic CasparCG.

CasparCG Server Installation • Check that your system meets the System requirements. • Unzip and place the CasparCG Server folder anywhere you like. • Install Microsoft Visual C++ 2010 Redistributable Package' from • Install 'Flash Player 10.3.183.11' from the 'Flash Player Installation' folder.

You can safely use the online update function, I tricked the driver date 100 years in the future so the present (and working) drivers are not overwritten during update.

• Make sure to disable the default Aero theme in Windows, as it interferes with CasparCG Server's OpenGL features. • Configure the server settings in the 'casparcg.config' text file. • Start the 'CasparCG.exe' program. • Connect to the server from a client software, such as the separate download, CasparCG Client 2.x.

All configuration of CasparCG Server is done in the text file caspar.config which can be edited in any text editor. If you want to change the location (for example to a faster disk) you just change the paths in the casparcg.config file. Use the character in front of any special character, so that C: CasparCG is written C: CasparCG At the bottom of the casparcg.config file you will find comments which document additional settings.

Paths Configuration To tell the CasparCG Server where to look for media files, change the following paths in the configuration file. You can change these paths to any path you'd like, for example a fixed path such as L: CasparCG or my-server or even a relative path (calculated from the Server's EXE file) such as Media sub-folder Please note: All paths should be terminated with a backslash (meaning that it should be entered as ). We recommend that you place your media and templates files locally, on a fast disk that is not the same disk used for the operating system.

• log-path: Path to folder with all logs. • media-path: CasparCG Server will look in the media folder (and its sub folders) for videos, audio and images files. • template-path: CasparCG Server will look in the templates folder (and its subfolders) for Flash templates. • template-host: Path to Flash TemplateHost files. • data-path: Path to folder where 'data' is read from and written to. CasparCG Server will look in the data folder (and its sub folders) for data loaded by Flash templates. C: casparcg _media C: casparcg _log C: casparcg _data C: casparcg _templates cg.fth.20.

Log Available in version 2.1.0 onwards. Allows a remote client to monitor the Caspar CG Server log by connecting to the defined port, if added to the config file in the controllers section as shown below (other controllers not shown. 3250 LOG Implemented by in this log-level Increase or decrease the amount of logging. Options are: • error • warning • info • debug • trace.

Diagnostics The diagnostics window can be opened using the AMCP command DIAG Graphs option determines whether the diagnostics window will display graphs or not. True [true false] See graph descriptions for more information about interpreting diagnostic graphs. Auto-Mode CasparCG Server 2.0 supports automatic real-time conversion of video-files encoded in other video modes than the channel is running. Note: Auto-mode is highly dependent on that the clips are encoded correctly with frame-rate and interlacing meta-data. [true false] Buffering buffer-depth [2.] Buffer depth configures the depth of CasparCG Server's consumer buffers. Lower buffer-depth will decrease frame latency, however the software will be less tolerant to performance spikes.

Different consumers have different minimum buffer-depths to function properly. The buffer-depth setting should be set to the highest depth of any of the used consumers. It is recommended (but not required) to use a buffer-depth of 2 frames over minimum. Consumer Minimum buffer depth Bluefish 2 Decklink 3 Decklink + emb audio 4 Decklink + low-latency 2 Decklink + emb audio low-latency 3 Screen 2 Audio 3 pipeline-tokens [2.] The number of tokens that can be active in the rendering pipeline. Currently the pipeline has two parallel stages so for maximum performance you should have 2 tokens. Adding more than 2 tokens can provide buffering for hiding performance spikes. Each token causes a delay of 1 frame, so setting it to 25 causes the pipeline to render at maximum performance (since >=2) and then adds 23 frames of extra buffering.

Setting pipeline-tokens to 1 for a channel reduces the delay from input to output by 1 frame. Please note that reducing the delay/buffering can have impact on performance and spike tolerance. Channels Configuration The resolution and frame rate of the channel must be specified.
