Description

I want to display incoming stream on a Decklink card and do it with the following command:

$ ffmpeg -y -i "udp://IP:PORT?overrun_nonfatal=1" -f decklink -pix_fmt uyvy422 -s 720x576 -r 25000/1000 'DeckLink Quad (1)'

This issue hard to reproduce as it can work a long time without any problems, but need await and I'll start to receive the following errors:

After that these errors fall down constantly. I think it's a bug as this issue easy to fix using the FFmpeg restart. This is not an isolated case, I found the same problem at the stackoverflow
