[ffmpeg] What are the best settings for flv encoding?

[masterpingouin]

Hi guys,

I'm using ffmpeg for a while, in order to convert wmv videos into flv, but i still have a lot of macroblocks :

Here's my setting to encode a 512x384 video :

ffmpeg.exe -i videoinput.wmv -acodec mp3 -ab 48 -f flv -s 512x384 -ar 22050 -ac 1 -aspect 4:3 -g 12 -b 800 -qmin 2 -qmax 10 -r 25 -y videooutput.flv

So what should i do?
(By the way, i want to keep the bitrate)
