What format/syntax is needed for ffmpeg to output the same input to several different "output" files? For instance different formats/different bitrates? Does it support parallelism on the output?

I use
ffmpeg -f lavfi -re -i 'life=s=300x200:mold=10:r=25:ratio=0.1:death_color=#C83232:life_color=#00ff00,scale=1200:800:flags=16' \
-f lavfi -re -i sine=frequency=1000:sample_rate=44100 -pix_fmt yuv420p \
-c:v libx264 -b:v 1000k -g 30 -keyint_min 60 -profile:v baseline -preset veryfast -c:a aac -b:a 96k \
-f flv "rtmp://yourname.com:1935/live/stream1" \
-f flv "rtmp://yourname.com:1935/live/stream2" \
-f flv "rtmp://yourname.com:1935/live/stream3" \
I have done like that
ffmpeg -re -i nameoffile.mp4 -vcodec libx264 -c:a aac -b:a 160k -ar 44100 -strict -2 -f flv \
-f flv rtmp://rtmp.1.com/code \
-f flv rtmp://rtmp.2.com/code \
-f flv rtmp://rtmp.3.com/code \
-f flv rtmp://rtmp.4.com/code \
-f flv rtmp://rtmp.5.com/code \
