I have posted a revised and extended version of my “Introduction to CasparCG Graphics System” document. I have added descriptions of the mixer tools, receiving and outputting SDI and data-rate reduced streams, and how to use the call facilities in some of the producers.
The document is in PDF format to allow for download and use when network access is not available. It can accessed at https://github.com/amwtech/CasparCG_Documentation.
I hope this will help new CasparCG users get more out of their installations.
