[FFmpeg-user] Is there a better way to do this

I am using:
ffmpeg -async 1
       -f alsa
       -ac 1
       -i hw:1,0,0
       -f x11grab -s 1920x1080
       -r 25
       -i :0.0
       -acodec libmp3lame
       -ar 22050
       -ab 64k
       -qscale:video 4

Works reasonably well. But in the man page I do not see the parameter
'-ab' described. Should I use something else for this?

I also get:
[swscaler @ 0x13d3100] deprecated pixel format used, make sure you did set range correctly

What am I doing wrong here?

And if I could do this otherwise better I would like to hear about it.
