I don't know if it's supposed to have that as a feature or not. Probably 
not, since there are other tools to do it.
Or it may be that it supports it already, but I just don't know how to 
make it do it.

I suppose it would be a nice feature since ffmpeg is a major player for 
converting video to flv for streaming but there are other tools so it's 
not really a big issue at all.

To clarify, the flv files which ffmpeg creates are perfectly playable. 
They don't need a keyframe list in the /metadata/ area to be played. The 
keyframe list is just to help streaming players know where (in bytes) to 
seek to in order to find a keyframe -- even if that byte offset has not 
been loaded over the network yet.
