What parameters are you currently using?
Try this:
/usr/bin/ffmpeg -i /path/to/your/input.avi -f flv -acodec mp3 -vcodec flv -ab 56 -ar 22050 -r 15 -s 320x240 -qmin
4 -qmax 10 /path/to/your/output.flv
play with qmin/qmax to adjust the variable bit rate. Have a look also at http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC15

i am using these:
/usr/bin/ffmpeg -i /path_to_file -s 480x360 -deinterlace -ab 32 -r 15 -ar 22050 -ac 1 /path_to_flv
i will add your parameters to see the difference and i will tell you the result...
i will take a look also to the link.
thank you for your time...

With that string you will be using the default video bitrate as you haven't set -b (in bits per second)
I think the default bitrate is 200kbit (i.e -b 200k) which is quite low for a clip of that size.
