First, please note that I do not yet have any Blackmagic products -- I am investigating them with the view to possibly using them in a product (this means that at the moment any understanding I can have of the DeckLink API SDK can be purely theoretical; I cannot at present experiment to see what things do). Second, I am entirely new to the field of video capture, so I am not entirely sure what the questions are that I should be asking and I may not quite have the correct terminology.
The scenario is as follows: I am working on a training device that will present an instructor with 6 - 8 displays of what students are doing / seeing on the training device. (All these displays are generated via a Windows 10 PC at the instructor station.) One of the screens will be an Ultra HD display. During a training exercise we need to record the screens plus an audio channel so that the instructor can play back (including rewind / fast forward / jump to markers etc) after the training exercise to review it with the students.
To implement this record and playback functionality we are thinking of using a number of Intensity Pro 4K or DeckLink cards. We are intending to use an API to control recording and playback via the cards. Looking at the SDK documentation I saw that there are "IDeckLinkDeckControl::StartCapture" and "IDeckLinkDeckControl::CrashRecordStart" methods (section 2.5.26.28 and 2.5.26.31). However I notice that at the start of 2.5.26 that the IDecLinkDeckControl is for controlling interfaces via RS422 (which is not applicable for the cards I am considering). Can I use these methods to set these cards recording and if not what methods should I be using?
It could be that I am completely up the wrong tree, if so please can someone point me in the right direction for what I am trying to achieve.
Many thanks,
Andrew Ch.
