Has anyone ever setup a encode/decode pair using FFMPEG and Decklinks? (or any other software?). The end goal is to bring in a remote camera feed into the studio switcher so quality and low latency is important. There is a private ethernet network already setup between the two studios.
I'm testing using this on the encoder (10.40.0.100)
and on the receiving computer (10.40.0.111) I'm just trying to playback using ffplay (eventually this will output to another decklink)
but the playback is unstable and I get all these errors. I'm sure I have some settings wrong but no idea what.
Any guidance would be appreciated.

ffmpeg -f decklink -video_input 'sdi' -i 'DeckLink SDI (1)' -f mpegts udp://10.40.0.111:8090
