FLV is a format, H.264 is a codec. The FLV container can hold H.264
video, and ffmpeg's multiplexer does support that.

And I'm sure ustream's FAQs recommend H.264 as a codec.

So if it must be FLV _format_:
  -c:v libx264 -f flv
or in your case:
  -c:v copy -f flv

That _should_ work, at least from ffmpeg's perspective, and probably
from ustream's as well.
