Hi there,
I have successfully compiled FFmpeg with the decklink SDK. FFmpeg list successfully all the inputs but when I try to capture using the command below, it returns an error : Decklink Quad (1): Device not configured. Still I have configured the card with the Desktop Video Setup (all connectors are inputs) and the 1st has a input signal.
Do I miss someting? Should "configure" the card in a way upfront?
The command: ffmpeg -format_code Hp25 -f decklink -i 'Decklink Quad (1)' -c:v libx264 -preset fast -video_size 1920x1080 -framerate 25 -an truc.mp4
The trace:
