Hello All,
I want to develop Linux based video loop-back application which captures 10-bit uncompressed sdi video from Decklink quad card, insert caption into the captured RAW video frame and display it on sdi output port.
What should I do ? I am familar with "Blackmagic_DeckLink_SDK_9.7" APIs and played with Capture demo and created (& tested) Display demo which reads 10-bit uncompressed frame data from RAW video file and display it on SDI output.
What can be my next step? I have gone through APIs like "GetBufferForVerticalBlankingLine" by which I can have pointer to video ancillary data but I don't know what to do next !!
Thanks,
ALM
