Configuration
It is relatively complex, because there are no setup program or even dialogs and configuration mainly relies on editing XML. Besides this, external components, as CasparCG or MySQL should be configured in its own way. Dont't hesitate to contact me until this.
If you want to setup a playout, you probably know, how many video input and output lines are required. Important, and specific to this playout concept is to have exactly two video outputs for every running channel. These are Program (PGM) and Preview (PRV). PGM is the main video output, PRV also plays everything in rundown simultaneously, but also allows to preview, check and trim clips that are ready to play. PRV can also act as Preset (PST) and display first frame of next clip ready to play.
If you plan to use live inputs, keep in mind that single input can be opened only once and must be serviced by the same instance of CasparCG as output. So, to play live on both - PGM and PRV (as it is required for full redundancy), you will need also 2 inputs. Among Decklink cards, currently only Extreme series are able to use input and output simultaneously. With all the other types you are required to have separate card instance for input and output (assuming that Decklink Duo is two-instance card). You shouldn't consider using one Decklink card with internal keying enabled as it's not intended to this purpose.
You have to configure CasparCG outputs (here named channels, what can be confusing) to be able to play individual files as well as live input. Caspar don't allow defining inputs, but we have to have direct 1:1 assignment between inputs and outputs. In fact CasparCG allows to play on its individual channel even several inputs simultaneously, but in this project it is limited to one (but can be extended if required). Refer to CasparCG wiki, setup it (or them - you can have separate machines for PGM and PRV) and record:
- CasparCG channel numbers for every output,
- live input device name assigned to every output for (e.g. DECKLINK 3 for CasparCG channel 1,
- IP address of the CasparCG machine, and port number (typically 5250) for AMCP control.
Information about CasparCG devices that application uses exists in database table tas.server. There is single record for each CasparCG available.
