Depends on the length/quality/willingness to spend. If it's short, you can use 
SWF (ffmpeg can do this), that has an upper limit of 15,000 frames IIRC. 
ffmpeg can also encode to flv, however I don't know what codec it uses when 
doing that, but I expect it's the older one (vp3 maybe?). If you don't mind 
going closed-source, you can buy a library from On2 that does vp6 (again, I 
think that's the name) which is the higher quality one.

The audio the flash player expects is MP3, so you may have to do a custom 
build of ffmpeg to get that in there, it's not on in some distros by default.

Another option is to use the MS variant of DivX, which should play by default 
in WMP, I've done this with mecoder, but not recently, so I can't remember 
the command line options (there is an mecoder frontend I think though). The 
codec name is msmpeg4 or msmpeg4v2 (I don't know the difference between 
them).
