Why is the ffmpeg signal missing?

Question

YouTube

I use the following streaming code

ffmpeg -i "rtmp://server" -vcodec libx264 -x264opts "keyint=3:min-keyint=2:no-scenecut" -preset veryfast -maxrate 1984k -bufsize 3968k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 96k -ar 44100 -f flv -s 1920x1080 rtmp://b.rtmp.youtube.com/live2?backup=1/ID

The quality of the stream is high for the first ~10 seconds, but then it becomes "NO DATA" and the error "
Unable to receive data from the video encoder. Check its parameters in the broadcast settings." appears, although ffmpeg continues to work.

Answer 1

The problem was that ffmpeg didn't have time to convert the data. With the transition to a more powerful system and a wider channel, the problem was solved.
