As with any update there is a chance that your command could become

Both of these commands should still work although flv (the encoder)
won't give as good results as libx264 for flv (the container) output.

Many of your options are outdated, but if you wanted to use this
particular command an updated version would be something like:
ffmpeg -i input.flv -acodec aac -strict experimental -ab 128k -vcodec
mpeg4 -b 1200k -mbd 2 -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2 -s
320x180 -metadata title="X" output.mp4
"ffmpeg -h" will give you a massive list of the option names.

ffmpeg -i input.flv -b 768k -s 320x240 -vcodec libxvid -ab 128k -acodec
aac -strict experimental -ac 2 -ab 64k output.mp4
Alternatively you could replace "-acodec aac -strict experimental" with:
* "-acodec libfaac" or...
* "-acodec libvo_aacenc" if you compile FFmpeg to support these

Error messages are always more useful than, "this didn't work".
