Hi Moritz, I forgot to write my full command down, because I do this already: ffmpeg -i rtmp://localhost/live/stream -s 512x288 -c:v libx264 -crf 23 -preset slow -g 25 -c:a copy [...] -f flv rtmp://output1 -c copy -f flv rtmp://output2 With this command output2 is a bit faster in time then output1. When I transcode both outputs it would be sync.
