Can you help me optimize my FFMPEG settings for streaming?

I want to optimize settings in ffmpeg for streaming. This is what I am currently running however I've basically copied and pasted different things I've found. I probably have some duplicate settings overlapping. Could a more experienced user please confirm if this is good?

sudo modprobe snd-aloop pcm_substreams=1

FFMPEG=ffmpeg

GIF=

STREAM_KEY=

URL=rtmp://a.rtmp.youtube.com/live2/$STREAM_KEY

FPS=30

KEYINT=$(expr $FPS * 3)

TEXT=/tmp/current_song.txt

COLOR="0xFFFFFF"

BCOLOR="0x000000"



$FFMPEG -thread_queue_size 512 -f alsa -ac 2 -i hw:Loopback,1,0 -fflags +genpts -ignore_loop 0 -r $FPS -i $GIF 

-vf drawtext="fontfile=/usr/share/fonts/truetype/freefont/FreeSans.ttf:bordercolor=$BCOLOR: borderw=1: fontcolor=$COLOR:textfile=$TEXT:reload=1:y=10:x=5" 

-vcodec libx264 -x264opts keyint=$KEYINT:min-keyint=$KEYINT:scenecut=-1 -b:v 5000k 

-preset veryfast -s 1920x1080 

-c:a libfdk_aac -b:a 128k -ar 44100 

-f flv $URL

And here is the log dump

Why the duplication? It's hard to answer your question without knowing the context of what you are trying to do.

3 mbps max bitrate seems a bit low for 1080p. Are you happy with the quality you get at that bitrate? Do you have some kind of slow DSL link you want this to work over, or some other reason for keeping the bitrate that low?
