You need to choose those options for yourself. The FLV format supports
multiple video and audio codecs, you will need to choose codecs for
both audio and video and tune the options so that the right size and
quality of transcode is produced.

Purely as an example, FLV supports H264 and AAC audio, so this might
work, depending upon the source file:

ffmpeg -i source.wmv \
  -codec:v libx264 -crf 18 -preset veryslow -tune film \
  -codec:a libfaac -ab 128k out.flv

For more details on what options you can use, you can refer to the documention:
