+The decklink input device provides capture capabilities for Blackmagic
+DeckLink devices.
+
+To enable this input device, you need the Blackmagic DeckLink SDK and you
+need to configure with the appropriate @code{--extra-cflags}
+and @code{--extra-ldflags}.
+On Windows, you need to run the IDL files through @command{widl}.
+
+DeckLink is very picky about the formats it supports. Pixel format is
+uyvy422 or v210, framerate and video size must be determined for your device with
+@command{-list_formats 1}. Audio sample rate is always 48 kHz and the number
+of channels can be 2, 8 or 16.
