Stream lags for high fps scenes.. FLV to RTMP

[SmokeKush]

Greetings.

I am streaming a flv file to an rtmp destination. For most stuff it works perfect... tv, baseball, etc. But it seems for very high framerate stuff like hockey, there is tiny lag between frames. Even if I increase re-stream framerate, it still happens.

Not many complain... there is still 1500+ ppl who watch, but it bothers me.

Anyone have suggestions? This is my command. Thank you.

ffmpeg -re -i input.flv -vb 600k -minrate 600k -maxrate 700k -bufsize 1600k -aspect "16:9" -s "640x360" -c:v libx264 -profile:v "Main" -level "3.1" -r 30 -g 30 -keyint_min 60 -x264opts "keyint=60:min-keyint=60:no-scenecut" -c:a libmp3lame -ab 128000 -ar 44100 -ac 2 -f flv "rtmp://destination/key"
