Detailed Description
This class uses the Blackmagic Decklink libraries, to send video streams to Blackmagic devices.
This requires special hardware manufactured by Blackmagic Designs. Once the device is acquired and connected, this reader returns openshot::Frame objects containing the image and audio data.
