Convert AVI to Flash Video (FLV)

I need to convert a standard AVI (both audio & video) to a flash video file (FLV). The program will be run from the command line; the input will be a .avi file and the output will be a .flv file. If possible I would like to be specify the type of flv file in the command line arguments (progressiveo or not, compression size, etc). Please specify in your bid what variables can and can not be set when creating the FLV. Right now I prefer using the sorenson codec, but if you have a better codec i'm open to change. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
