Hi, In my setup I have two decklink cards, 'DeckLink SDI Micro' and 'DeckLink Mini Monitor 4K' I'm trying to get "DeckLink Mini Monitor 4K" to work with ffmpeg but it doesn't seem to be detected by ffmpeg.

Mini Monitor is an output only card, and you are listing the input devices. For output devices you should do something like:
ffmpeg -i test.avi -f decklink -list_devices 1 dummy The manual gives this example as well.
