[Red5] ffmpeg-php and the like

[red5 at allwebnow.com]

  Does anyone know of a "more developed" opensource or commercial ffmpeg
  (or the like) browser based program (php or java) that would let our
  clients use to convert their mpegs,wmv,avi,mp3 into flv's and fix
  corrupt flv's.  Without having to download and pay for software in a
  fairly coherent web panel?  Any links or direction on this would be
  great.

  Thanks,
  Ben
