you are correct, ffmpeg produces FLV very quickly and I have done a
visual diff sx theora dx flv and I have noted that flv has less frame
during camera motion but, globally, it's quite comparable with Theora
even more crisp; more FLV is produced in  30-40% less time than theora
using always ffmpeg. (internal theora codec)

ffmpeg2theora instead uses more time to do the same.

So two order of doubt about latest ffmpeg release
1) why ffmpeg->FLV encoding is so quickly compared to ffmpeg->theora 
2) why ffmpeg->theora is quite quikcly compared to ffmpeg2theora from J.

I think this is not a poor question as time encoding is more than 5-10% 

do you have a clue ?
