  How do I add subtitle in an image with decklink SDI?

  Posted by Robert Pattinson on March 25, 2012 at 8:42 am

  I am using decklink SDI to display video.

  I use IDeckLinkOutput::DisplayVideoFrameSync method to display each image.

  Now I need to add subtitle in images, how can I do it?

  I found IDeckLinkOutput::CreateAncillaryData method in Blackmagic Decklink SDK.pdf, but there is no example code for it, I don’t know what ancillary data can do, neither how to.

  So, how can I add subtitle to images when I display them?
