I am using decklink quad 2 for output device...but have tried decklink 8k pro and others with the same result using FFMPEG.
Example code:
ffmpeg -re -rtsp_transport tcp -i
rtsp://xxxxxx/live/test -ar 48000 -probesize 32 -analyzeduration 40 -rtbufsize 0 -f decklink -pix_fmt uyvy422 -s 1920x1080 88:a3f351e3:00000000
Using OBS NVNEC @ 60 fps as streaming source to nimble server.... other encoder side settings do not have an effect as we get 4 seconds of latency...
I have also tried
rtmp streams and it has basically the same result.
I can use the same hardware and OBS streaming config and when using g
streamer we can get sub second delay. Also using OBS built in tools we get very low latency when using the BM decklink...it seems lots of people have the issue when doing a google search for FFMPEG and decklink...just have not found the soultion. thx
