Dear ffmpeg community, I am using ffmpeg in an nginx environment to reencode Livestreams on Ubuntu.
So there are 2 Livestreams with the exact identical options going into the reencode. Both are streaming to a server in germany - one comes from germany, the other comes from the US eastcoast. So I have the problem, that Twitch moans after some time about the Keyframe Interval of the stream coming from the US. This is the line I am using to reencode: exec_push ffmpeg -i rtmp://localhost/input/$name -c:v libx264 -preset slow -profile:v main -b:v 2175k -minrate 2175k -maxrate 2175k -bufsize 2175k -r 40 -g 80 -c:a aac -strict -2 -b:a 160k -f flv rtmp://server \-c copy -f flv rtmp://server; Does anybody have a clue what could cause this and how to prevent it? Changing x264 cpu preset on the machine where the stream comes from to something faster doesn't work, and the reencode-server is just at ~50% usage with 'slow' as well.
