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.
