need batch video transcoding to flv apis (preferrably for unix)

I am looking for APIs to help batch conversion of various video formats into .flv. I would prefer these APIs be for UNIX/FreeBSD. The problem I have is a video provider ftp'ing video files to my server and I want to have scripts that automatically convert the video into .flv for my site rather than using Sorenson or Flix by hand to convert the video.

Thanks - Bill

Hi.
The Flix Engine does that, but it runs on Windows.
