Hello, I'm using ffmpeg's - format Code to set the video output format. I want to output video in I format through blackmagic. I set the format Code hi50, but the video display format is P50, and there is no error. Here is my test instruction:

ffmpeg -protocol whitelist "file,udp,rtp" -loglevel debug -re -i " udp://192.168.15.19 :1234?overrun onofatal=1&fifo size=50000000" -vcodec v210 -pix fmt yuv422p -c:a libfdk aac -max muxing queue size 1024000 -f decklink -format_ code Hi50 -s 1920x1080 -r 50 "DeckLink 8K Pro (1)"

Hey,

I had a similar problem with FFMPEG and Decklink before and just stumbled about your Issue. Unfortunally the Decklink Card doesn't care about the Output Type in FFMPEG. You must set the Output-Type in the Blackmagic Desktop Video Tool to pSF instead of progressive Output.
